309 - Background Agents

contact@fragmentedpodcast.com (Kaushik Gopal) — Wed, 1 Apr 2026 00:00:00 +0000

Andrej Karpathy says the goal is to maximize how long an agent runs without your intervention. But there's a false summit most teams hit first: individual speed goes up while system speed stalls, your laptop roars under four parallel Gradle builds, and review queues back up. Kaushik and Iury trace the full arc — from local multitasking to cloud-hosted async work to fully autonomous agents that fire on repo events and put PRs in your inbox.

249 - Java and the JDK: Powering the Android Landscape with Michael Bailey

contact@fragmentedpodcast.com (Kaushik Gopal) — Mon, 10 Jul 2023 10:45:00 +0000

In this episode of our podcast, we explore the diverse landscape of Java versions within the Android ecosystem. Our guest is Michael Bailey, a seasoned Java expert who has been a frequent presence on our show since the early days of our podcast. We kick off with a solid foundation, discussing the differences between JDK and JRE, as well as the distinctions between the available Java JDKs. We also guide listeners through Android Studio settings, exploring how to select a suitable JDK, its utilization, and how it relates to JAVA_VERSION on one's home path/terminal.

As we dig deeper, we start to unpack some of the crucial Android app settings. From compileOptions to sourceCompatibility/targetCompatibility, we shed light on why these versions are important. We also demystify the compileSdk vs minSdk vs targetSdk, and how they interconnect. Drawing from Kaushiks's recent experience in building a new app, we provide real-life examples that can better clarify these topics for our listeners.

We conclude the episode by providing some valuable resources for further understanding and exploration. This episode is designed to be a comprehensive guide to understanding and navigating the intricacies of Java versions in Android development.

In this edition of Fragmented, we're thrilled to host Ishan Khanna, a software engineer at Tinder who possesses great enthusiasm for feature flags and A/B testing. Donn discusses why he invited Ishan on the show, highlighting Ishan's passion for feature flagging and A/B testing. The conversation kicks off with an insightful story from Ishan about feature flagging at Booking.com, leading to a discussion on the difference between A/B Testing and Feature Flags, when and why to introduce feature flagging, and how to measure its effectiveness. The show also focuses on the benefits and risks of feature flagging, along with ways to manage potential complexities in the codebase.

We then delve deeper into the topic of feature flagging, covering how to get started, what to look for in a tool, and the role of testing. Discussion points include the best practices for rollout percentages, considerations for multi-platform implementation, and the specifics of targeting in feature flagging. The conversation wraps up with an exploration of available tools for those looking to introduce feature flagging or A/B testing frameworks into their operations, examining when it might be necessary to build a bespoke solution.

The episode offers a wealth of resources for listeners, including links to an array of feature flagging and A/B testing tools, such as Firebase Remote Config, Optimizely, and LaunchDarkly. For more insight into the topics discussed, Ishan recommends his Droidcon Berlin talk on 'Customer Driven Development' and Stuart Frisby’s talk on A/B Testing.

247: The Art of App Modularization with Siggi Jonsson

contact@fragmentedpodcast.com (Kaushik Gopal) — Mon, 12 Jun 2023 05:00:00 +0000

In this episode, we talk to, Siggi Jonsson. Siggi helps guide us through the complex and often confusing world of Android app modularization. Our conversation will begin by shedding light on the importance of modularization, what triggers the need for breaking projects into multiple modules, and how modularization relates to team size, feature teams, and code ownership. This discussion is aimed at demystifying how and why developers often choose to modularize their applications.

As we move forward, we'll dive into more advanced aspects of modularization, such as the challenges of scaling and the potential missteps in over-modularization. Drawing on real-world experiences, we'll examine the red flags that signal a need for revising your modularization strategy. This part of our discussion will also highlight some specific tools and techniques that can help manage and visualize your project's modularization, and Siggi will share his own experiences and insights into how these tools have assisted in his modularization strategy.

In the final part of the episode, we'll touch on the benefits and strategies of proper modularization. Siggi will share practical advice on how to tackle big projects, fix issues with modularization, and make a smooth transition from monolithic to modular structures. We'll also talk about some tools that can be handy in this process. Before closing, Siggi will offer his top tips for developers embarking on their modularization journey and share some valuable resources to help them. Siggi will also provide updates on his latest work and how listeners can reach out to him.

246 - Dependency Injection: Kotlin Inject with Fred Porciúncula

contact@fragmentedpodcast.com (Kaushik Gopal) — Mon, 29 May 2023 05:00:00 +0000

In this podcast episode, we have the pleasure to host Fred Porciúncula, a Google Developer Expert (GDE) known for his work with Kotlin Inject and his invaluable contributions to the Android development community. Fred offers his expertise on Dependency Injection (DI), Kotlin Multiplatform (KMP), and how they intersect.

We kick off the conversation by discussing Dependency Injection (DI), its importance, and the options available to developers, including Dagger, Hilt, Anvil, Koin, and Kotlin-Inject. Fred explains the use and impact of DI in the Kotlin Multiplatform (KMP) world, considering Dagger’s current lack of KMP support and debating whether one should use separate DI tools for Android apps and KMP components.

Delving further into Kotlin-Inject, we explore its features, usage, and how it differentiates itself from other DI solutions. Topics discussed include its unique handling of Scopes, its support of constructor injection, and its utility in building dependency graphs. Furthermore, we examine the timeless debate of Dependency Injection versus Service Locator.

Toward the end of the episode, Fred presents his thoughts on the advantages and disadvantages of exclusively using Kotlin-Inject throughout an application. We also tackle the concept of “Vanilla Injection” - refraining from using DI libraries at all.

For further learning, we recommend resources like Fred's insightful article on transitioning from Dagger/Hilt to Kotlin-Inject, a Dagger issue discussing KSP support, and a Kotlin-Inject discussion on Anvil-like features. Links to these resources, among others, are provided below. Don’t miss out on this engaging and informative episode with Fred Porciúncula!

contact@fragmentedpodcast.com (Colin White) — Mon, 15 May 2023 05:00:00 +0000

In this episode, Donn and Kaushik talk to an old friend of the show, Colin White, about Treehouse, a combination of the Redwood and Zipline libraries.

Colin is a Staff Engineer at Cash App (Block).

Redwood is a multiplatform Compose library that allows you to target multiple UI toolkits on various native platforms. Ultimately this allows you to share presentation logic.

Zipline is a multiplatform JavaScript engine for Android, iOS, and the JVM, which uses Kotlin for calls in/out of the JavaScript land. This allows you to update the application logic of your apps without the traditional song and dance of the app store approval and release process.

Treehouse is the combination of both libraries, Redwood and Zipline. Listen in to learn more ...

242 - Kotlin Code Formatting with ktfmt and spotless

contact@fragmentedpodcast.com (Kaushik Gopal) — Mon, 20 Mar 2023 05:00:00 +0000

In this episode, Donn and Kaushik talk about one of the age old bike shedding topics - code formatting, and how you can solve it with automation and tools.

Code formatting can turn into an endless debate amongst peers and teams, and what Kaushik and Donn have found is that this can be delegated to a tool and automated. Freeing you and your team of having to worry about proper indentation, bracket placement, etc. By relying on a well defined tool and some automation you can clean your code up, make it much more uniform and easier maintain.

We talk about ktfmt, a Kotlin code formatter that was released by Facebook. We dive into ktlint, detekt and more. We also dive into spotless which can help you by integrating ktfmt into your gradle build pipeline.

241: The Pressure to Ship. Fear, Uncertainty and Doubt

contact@fragmentedpodcast.com (Kaushik Gopal) — Tue, 10 Jan 2023 13:30:00 +0000

In this episode, Donn and Kaushik talk about the fear of shipping, some impostor syndrome and how it contributes to uncertainty and doubt in your capabilities as a software developer.

Recently Donn embarked on a mission to come up with an idea and ship it within 24 hours (which he did do). The end result was a net benefit of confidence, speed and skill acquisition. This helped reduce any doubt, uncertainty and ultimately fear of shipping a product faster.

That's what this conversation is about ... how to doing a project like the 24 hour MVP can remove fear, uncertainty and doubt and help you ship your side project/products faster.

239: Require PR Reviews with CODEOWNERS

contact@fragmentedpodcast.com (Kaushik Gopal) — Mon, 28 Nov 2022 16:00:00 +0000

In this short episode, Donn talks about the CODEOWNERS file and how it can help you ensure teams review the code that they are responsible for before merging.

The CODEOWNERS file is a file that you drop into the root of your project (or into the /docs or .github/ directory) that tells GitHub (or whatever git host you're using) to require a review for any code changes that match the patterns as defined in the CODEOWNERS file. You'll specify a matching pattern and users, or teams that own that pattern of files and they will be required to review the PR before it can be merged. This helps prevent unwanted changes to files that may or may not be owned by one team or another. This is useful as teams grow larger and need more control over the changes in their application codebase.

232: Frustration, Flow State and "The Madness"

contact@fragmentedpodcast.com (Kaushik Gopal) — Mon, 13 Jun 2022 05:00:00 +0000

In this episode Donn and Kaushik talk about frustration, finding "flow state" and how it's known as "the madness" and how to deal with it.

We originally were going to talk about an other topic, but during the off air banter Donn brought up how he was frustrated with losing/burning so much time on a task that he had for his side project. He only meant to spend a little bit of time on it and then spent WAY more time than he meant to. He got to the point where he had to stop working on the project, yell at himself for not time boxing it and then he had to refocus. This piqued Kaushik's interest and they decided to hit record to talk about this topic as its something they both deal with and have also hear many other developers deal with too.

The "Madness" is when you get consumed by your work and you're so passionate that you lose track of time, eating and more. You've become consumed ... you have "The Madness". This happens to all developers, and Donn and Kaushik talk about how to not let this derail your day when you have other responsibilities as well as life and work. We hope you enjoy today's off the cuff developer discussion.

230: Feeling Like an Idiot

contact@fragmentedpodcast.com (Kaushik Gopal) — Mon, 30 May 2022 05:00:00 +0000

In this episode Donn talks about that pit of the stomach feeling we all get when we feel like we should know something but we don't. It's that voice in our head as developers that makes you feel like an idiot even when you're not.

Donn gives examples of how even senior engineers are subject to this feeling and how they are often the ones to not speak up about it simply because of their experience level and seniority.

This episode talks about why we get this feeling and how to combat it going forward.

229: Native Where You Need It with Turbo (Launch Your Side Projects Faster)

contact@fragmentedpodcast.com (Kaushik Gopal) — Mon, 23 May 2022 12:15:00 +0000

In this episode, Kaushik peppers Donn with questions about his foray into Android Turbo, Hotwire, and the concept of "Native Where You Need It".

Donn recently launched Android Jumpstart, the Android client for the Jumpstart Rails trifecta. Jumpstart Rails allow you to launch your SaaS business much faster than if you were to do it from the ground up.

The Android client for Jumpstart Rails builds on top of Turbo and Hotwire, two technologies that help power the Hey email client and Basecamp (the project management app). By using Turbo and Hotwire you're able to get very fast response times and speed with "HTML Over the Wire" (aka Hotwire) with Websockets and much more. This allows your web app to be super fast and when packaged with Android Turbo, allows your web app to live within a native shell. HOWEVER, this doesn't mean its simply a web wrapper. With Android Turbo you can specify which URL routes you'd like to be as native and which ones you'd like to remain web-based. This means you can choose to use Native when you need it, and delegate back to the web for everything else.

This is the solo founder, indie-hacker, and startup SaaS dream come true. You can come to market faster, iterate with a smaller team and get native benefits when and where you need it, all while also allowing your application to be flexible in a web manner.

If you're thinking about building a SaaS app that needs a web presence, Android and iOS presence but want fully native experiences in certain areas then this will be the episode for you.

216: Code Conventions - Why It's Important to Follow Them

contact@fragmentedpodcast.com (Kaushik Gopal) — Wed, 23 Jun 2021 17:51:29 +0000

In this episode, Donn talks about the importance of following code conventions and coding styles in codebases.

You'll run into various different coding conventions throughout your career. Sometimes it's as an employee, sometimes it's as a freelancer or consultant or just a small side project. The number of coding "styles" that you'll see will blow your mind as you work through your career. The big question is ... should you adhere to the current coding convention that is used in the app/file/etc or should you use your own favorite or an industry standard?

In this episode, I'll help explain the differences so you can make an informed decision going forward.

211: Why Learning React is Good For You as a Developer

contact@fragmentedpodcast.com (Kaushik Gopal) — Tue, 18 May 2021 05:00:00 +0000

In this episode Donn talks about why you need to learn React (or Flutter) - so you can truly understand the Unidirectional data flow pattern in a framework that was built for that purpose alone.

Working with other frameworks which bolt on a custom unidirectional data flow is often hard to understand. When you work with React and learn how it works, the concept of Unidirectional data flow starts to make much more sense as that is the default way to implement UI's in technologies like React (and Flutter).

This exposes you to the pattern and helps you understand it. In turn, this will help you become a better developer.

208: Developing Software at Startups with Jason Roberts

contact@fragmentedpodcast.com (Kaushik Gopal) — Mon, 26 Apr 2021 05:00:00 +0000

This is the original story of how Uber was built ... this is a fascinating story. You don't want to miss this. Donn talks to Jason Roberts. Jason was chosen to be Uber's CTO when the company was in its infancy (but didn't accept the offer). Jason shares the story of developing the code that eventually ran Uber from a couple of cars to a highly distributed system with an impressive amount of rides.

We talk about building what is needed when it's needed, the tools that he chose to build Uber's platform on. Early startup learnings, and how Uber originally ran on PHP before he chose to move it to Node.js.

Jason shares his story of how he met Travis (Uber's CEO who took it from a small company to a huge international corporation), how they built the systems, and team and much more. You'll learn how networking, working on interesting things, and seizing the moment and luck played into him landing his role at Uber.

Finally, we wrap up by chatting a bit about how being a generalist in an early-stage startup is beneficial (vs being a specialist).

We interrupt our regular programming for this extremely important message.

We stand with our black sisters and brothers against the evil that is racism. The recent events of police brutality and oppression against black people have been truly horrifying.

Please take the time to listen to the audio snippet on the #BlackLivesMatter movement from today's episode. It is a TedX talk by the far more eloquent Kennedy Cook who's voice and words are more powerful than ours.

We've never been very vocal about political issues at Fragmented. But that doesn't mean we don't care about these issues. On the contrary! We do our best to have our actions speak louder than our words and let others with first hand experience speak out. Then importantly we aim to listen.

But these aren't regular times are they? The horrifying brutality we're seeing against people of color is nauseating. The Covid-19 outbreak has made action particularly difficult so for today we will start with these words.

197: .git internals with Gordon 🔧

contact@fragmentedpodcast.com (Spec) — Mon, 4 May 2020 05:00:00 +0000

OK, If you really want to know how git works, this is the episode for you.
KG talks with his longtime colleague and mentor Gordon McCreight. Gordon is a
wiz in general but his knowledge of git goes deep. So in this episode, KG goes
solo and really dives in-depth about how git works.

Buckle up and listen on; you'll come out on the outer side with a much
sounder understanding of git.

Shownotes

Objects which are no longer referenced can be evicted with git prune; though this is a low-level operation which is often called from git gc. By default it will not remove commits newer than 2 weeks old, and of course the commits that are reachable from that; so provided the branch (or tag) deleted has recent commits, it will stay around in the git repository for up two a fortnight afterwards.

182: Where do I put DB objects in a modularized Android app?

contact@fragmentedpodcast.com (Spec) — Mon, 18 Nov 2019 05:00:00 +0000

App Modularization has plenty of benefits and a lot of Android devs today are starting to modularize their android app.

A common problem though that most folks will start to run into is - how do you manage your database objects in these modules? do you create a single module with all your database dependencies (modularize by layer), do you do the right thing and modularize by feature so each module has it's own database file etc.?

In this episode Kaushik grapples with that question and tries to come up with an answer.

176: Kotlin's !! Operator is a Code Smell

contact@fragmentedpodcast.com (Spec) — Mon, 30 Sep 2019 05:00:00 +0000

Kotlin isn't a magic bullet that prevents NullPointerExceptions.

Not at all.

What Kotlin does do is force you to think about how you want to handle your nulls. through Kotlin forcing you to think this through, the hope is that you'll avoid NullPointerExceptions. The only problem is, Kotlin has the !! operator, also known as the "Not Null Assertion Operator". This operator basically says "Hey Kotlin, trust me, I'm a pro, I know what I'm doing ... I KNOW THIS WON'T BE NULL".

This... is a code smell.

In this episode, Donn walks through why Kotlin's Not Null Assertion Operator (!!) is a code smell and what you can do to alleviate it.

One question that Kaushik and I get all the time is this ...

I'm starting to learn how to build Android apps, which language should
I learn? Kotlin or Java?

In this episode Donn answers this question and gives valid points on why both languages are valid options and why you might want to consider one over the other.

He provides caveats to why you might want to use one language over another and some of the trade offs of Java and Kotlin and how they operate together.

172: Coil Image Loading Library with Colin White

contact@fragmentedpodcast.com (Spec) — Mon, 12 Aug 2019 05:00:00 +0000

In this episode Donn and Kaushik sit down with Instacart Engineer Colin White to discuss a new image library he has created called Coil.

Coil is a Kotlin-first image library that focuses on ease of use, simplicity and extensibility. In this episode we ask him the question you're probably wondering ... "Why create an image library, isn't this a solved problem already?" and then move onto the details of how the library works, and what it offers developers.

From Donn's perspective - It's an interesting library and gives you what you need with minimal footprint but offers you the extensibility that you'd want in the future. Its a good balance of "just enough" and "I might need this".

Enjoy

171: Jetpack Compose with Leland Richardson

contact@fragmentedpodcast.com (Spec) — Mon, 29 Jul 2019 05:00:00 +0000

This week Donn and Kaushik talk to Leland Richardson from the Android team at Google about Jetpack Compose.

Jetpack Compose is declarative component-based UI runtime for Android. With compose you can build your UI with functions in Kotlin to easily "compose" what your UI would look like.

We dive deep in this episode. We talk about the background and influence React had on the project, we dive deep into some of the decisions made regarding the library and much much more...

We hope you enjoy ...

168: Learning Kotlin: Lambda Expressions Part 2

contact@fragmentedpodcast.com (Spec) — Mon, 8 Jul 2019 05:00:00 +0000

In this episode, Donn continues his talks about Kotlin Lambda Expressions. He explains how you can use lambda expressions as function parameters and as return types for functions.

This is a very dense episode - if you get lost look at the code snippets below or view on them on fragmentedpodcast.com


class LogReader {
    fun processFile(file: File, processLine: (String) -> Unit = {}) {
        file.forEachLine {
            println("Number of Chars: ${it.length}")
            processLine(it)
            println("Line Done Processing")
        }
    }

    fun processFileWithHandlers(file: File, logHandler: LogHandler) {
        file.forEachLine {
            println("Start of Processing")
            logHandler.handleLine().forEach { handler -> handler(it) }
            println("Line Done Processing")
        }
    }
}

interface LogHandler {
    fun handleLine(): List<(String) -> Unit>
}


val reader = LogReader()
val textFile = File("/Users/donnfelker/scratch/lorem.txt")

// Process with single lambda
reader.processFile(textFile, { println("First 10 Chars: ${it.substring(0..9)}") })

val logHandler = object : LogHandler {
    override fun handleLine(): List<(String) -> Unit> {
        return listOf<(String) -> Unit>(
            { line -> println("${line.substring(0, 1)}") },
            { line -> println("${line.substring(2, 4)}") },
            { line -> println("${line.substring(5, 10)}") }
        )
    }
}

// Process with multipe handlers via the logHandler

Kaushik decides to hit record on a skype call he has with friend of the show Jesse Wilson. They start off by discussing building features across different platforms today. Jesse talks about a clever mechanism of using javascript to change logic on the fly across the Square cash app, that's worked out pretty well. They then go on to discussing how one can try and converge across platforms in terms of business logic, architecture, naming etc. They then wind it down by discussing the state of Flutter, Kotlin multiplatform and reaching the promised land.

165: Learning Kotlin: Lambda Expressions Part 1

contact@fragmentedpodcast.com (Spec) — Mon, 17 Jun 2019 05:00:00 +0000

In this episode, Donn talks about Kotlin Lambda Expressions. He explains the syntax and how to build a couple of simple lambda expressions with and without type inference and declaration. We wrap up with a small example of passing a small lambda with multiple values to a function. See the show notes below for more info. This is part 1 of a multi-part series on Lambda Expressions in Kotlin.

The basic syntax of a lambda expression:

val myLambda : Type = { argumentList -> codeBody }

The codeBody is the only section that is not optional.

Double lambda expression (doubles an integer) with type inference

val double = { number: Int -> number * 2 }
val result = double(4)
// result = 8 now

Double string multi-line lambda with type inference.

val doubleString = { number: Int -> 
	// codebody
	val doubleResult = number * 2
	doubleResult.toString() 
	// Kotlin knows this will return a string
}

Type declaration in a lambda

val myLambda: (String, Int) -> String  = { str, int -> 
	"$str - ${int.toString()}" // "Donn - 32" 
}
val result = myLambda("Donn", 32)
// result = "Donn - 32"

Preview of next week … passing a lambda to a function

fun doWork(name: String, favoriteNumber: Int, someLambda: (String, Int) -> String) {
    // Do some processing, this is a contrived example
    val repeatedString = "$name$name"
    val result = someLambda(repeatedString, favoriteNumber)
    println(result)
}

// Usage
doWork("Donn", 32) { str, int ->
    val someNewValue = "$str is my parameter and so is $int"
    someNewValue.length.toString() // this is returned
}

// '37' is printed via println

// Or use it like this, the lambda code body is what can change, this is where the power is at
doWork("Donn", 32) { name, count ->
    var result = ""
    for(i in 1..count)  { result += "$name" }
    result // this is returned
}

// loops over and concatinates "Donn" until the favorite number (aka count) is met. 
// Output looks like: "DonnDonnDonnDonnDonnDonn..." and so on...

In this mini-episode dutifully does the yak-shaving for you and discusses what some options are and what the community has been gravitating towards.

Enjoy.

Shownotes

yak-shaving

Upday's convention:

Options

// option 1
fun getUser(): Single
// yuck

// option 2
fun user(): Observable
// but what does this mean?

// option 3
fun user(): Single
fun userUpdates(): Observable
// or
fun userStream(): Observable
// this is looking good

// option 4 (upday style)
fun userOnce(): Single
fun userStream(): Observable
fun userOnceAndStream(): Observable

Stay tuned for a future episode, where we discuss more details and more complicated cases to handle (like emitting a list of user, policies for fetching the first user as quickly as possible etc.).

Code Samples

Java

myObservable
	.map(...)
	.as(AutoDispose.autoDisposable(AndroidLifecycleScopeProvider.from(this)))
	.subscribe(...)

Kotlin

myObservable
	.map(...)
	.autoDisposable(AndroidLifcycleScopeProvider.from(this))
	.subscribe(...)

With Scope Event Provided

myObservable
	.map(...)
	.autoDisposable(AndroidLifcycleScopeProvider.from(this, Lifecycle.Event.ON_DESTROY))
	.subscribe(...)

Testing

// File: CustomerService.kt
class CustomerService @Inject constructor(...) {
	lateinit var scopeProvider: ScopeProvider
}

// Usage in Fragment/Activity/etc
val service = CustomerService(...).apply {
	scopeProvider = AndroidLifecycleScopeProvider.from(this)
}

// Usage in Test
val service = CustomerService(...).apply {
	scopeProvider = TestScopeProvider.create()

139: Static code analysis with Manu Sridharan

contact@fragmentedpodcast.com (Spec) — Wed, 24 Oct 2018 18:00:00 +0000

In this episode, Donn and Kaushik talk to Uber's Manu Sridharan on static code analysis. Manu's a badass who did his PhD on the subject! He explains how static code analysis works, how Uber leverages these tools in their app development pipeline and how we can use such tools to build high quality Android apps.

Note from Manu:

I found the story I was thinking about: Reed Hastings founded the company that built the Purify tool for debugging memory errors in C programs before founding Netflix. But, that's actually not a static analysis tool; it does dynamic analysis by adding extra metadata at runtime.

As far as the history of lint goes, from Wikipedia looks like Kaushik's guess was exactly right as to why it's called lint. Looks like the name goes back to the late 1970s.

But with the time, and the latest updates, that has become a tricky thing. This is a good problem to have for the ecosystem but it can make it seem very daunting for developers, both new and old.

133: Dependency Injection and Service Locators in a Kotlin world with Danny Preussler

contact@fragmentedpodcast.com (Spec) — Mon, 23 Jul 2018 05:00:00 +0000

A hotly debated topic at the moment is the use of a library like Dagger for dependency injection in the world of Kotlin. In this episode, we talk to Danny Preussler. Danny's a pro who's been around from the Java 1.0 days! He helps trace the history of dependency injection in Java all the way to today, in a Kotlin world where there exists alternatives like Koin and Kodine.

We dive into how some of these use a Service Loader/Locator pattern and the subtle differences with dependency injection. Listen on for an action packed episode.

111: Effective Java v3 - Item #5 - Prefer Dependency Injection to Hardwiring Resources

contact@fragmentedpodcast.com (Spec) — Mon, 29 Jan 2018 05:00:00 +0000

In this mini-fragment episode, Donn talks about Item #5 of the Effective Java (Third Edition) book - Prefer Dependency Injection to Hardwiring Resources.

Please note, this episode references the third edition of the Effective Java book that recently came out. Previously we were doing the entire series on version 2, but we are now upgrading to version 3 of the book. We will not be re-doing any of the existing lessons, but if one was inserted in the mix, then we will do that lesson. This is the case with Item #5. We did Item #5 previously for v2 of the book, but v3 introduced a new Item 5 (and bumped the previous Item 5 up to 6).

TLDR; Item #5 is new in the third edition of the Effective Java book. So listen closely. :)

109: Learning Kotlin - Sequences the new Iterables

contact@fragmentedpodcast.com (Spec) — Tue, 16 Jan 2018 05:00:00 +0000

In this episode of Fragmented, we go back to learning some Kotlin and look at the Iterable like data structure introduced called "Sequences". What is a sequence? How is it different from Iterable? When should I use it?

Show Notes

Eager/Lazy

Eager evaluation:

val lst = listOf(1, 2)
val lstMapped: List = lst.map { print("$it "); it * it }
print("before sum ")
val sum = lstMapped.sum()

// prints "1 2 before sum"

Lazy evaluation:

val seq = sequenceOf(1, 2)
val seqMapped: Sequence = seq.map { print("$it "); it * it }
print("before sum ")
val sum = seqMapped.sum()

// prints "before sum 1 2"

Source stackoverflow.com answer

Intermediate and terminal operations

Notice that at each chain operation, a new temporary list is created:

data class Person(val name: String, val age: Int)

fun main(args: Array) {
    val people = 
        listOf(Person("Chris Martin", 31), 
               Person("Will Champion", 32),
               Person("Jonny Buckland", 33),
               Person("Guy Berryman", 34),
               Person("Mhris Cartin", 30))
    
    println(people
            .filter { it.age > 30 } // new temp. list
            .map {                  
                it.name.split(" ").map {it[0]}.joinToString("")
            }  // new temp. list
            .map { it.toUpperCase() }) // new temp. list
}

Using a sequence:

println(people
        .asSequence()  // convert to sequence
        .filter { it.age > 30 } // lazy eval (intermediate op)
        .map {                  
            it.name.split(" ").map {it[0]}.joinToString("")
        }  // lazy eval (intermediate op)
        .map { it.toUpperCase() }  // lazy eval (intermediate op)
        .toList() // terminal operation
       )

Without a terminal operation, Sequences won't print anything:

val seq = sequenceOf(1, 2, 3)
println(seq) // prints address
println(seq.toList()) // [1, 2, 3]

You can't pick an index from a sequence:

println(seq[0]) // throws ERROR "No get method providing array access"
println(seq.toList()[0]) // 1

097 : Android Architecture Paging Library with Florina Muntenescu

contact@fragmentedpodcast.com (Spec) — Mon, 18 Sep 2017 05:00:00 +0000

In this episode Florina returns to talk to us about Google's recently announced paging library!

The paging library is a powerful take on implementing paging functionality in general, not necessarily linked to a paritcular technology or library. Florina breaks down the different components and explains what specific function each of them play.

We start off with DataSources, talk about when one would want to use "Tiled" or "Keyed" data sources, and then talk about making them work with RecyclerViews (which is really what 99% of us eventually want). Florina also explains the role of PagedLists, PagedListAdapters and so much more.

If you ever wanted to get an overarching veiw of Google's first take on implementing the paging library, this is a great starting point. Listen on so you can understand, try it out and then give feedback to Google, to participate in the making of this new library.

Micellaneous questions about Room (that we chopped off for lack of time)

Q: Does Room use reflection?

A: There's only 1 reflection call (at the time of finding the database implementation, when you call Room.builder). Most of the other stuff is generated code (with compile time verification!).

Q: Does Room provide compile-time SQL checks

A: Yes, Room was designed to provide compile-time checks.

Q: Does Room handle SQL injection attacks (security)

Yes ... for all practical purposes. See this post for times when it doesn't.

Q: Do we have tools to access the sqlite database file directly?

Nope, at the moment, adb is your friend. Use that to download the file manually from your device.

We've been using RxJava over the years now and have even talked to Dan about it in previous episodes.

How has our understanding of Rx use in Android changed over the years? We know some of the super standard usecases for RxJava in AndroidDev. But the important question to be asking is: when are the times we "shouldn't" be using RxJava? Are we over-complicating our code by shoe-horning it in different places. Concepts like functional programming and reactive state management have picked up steam again, how has this influenced our RxJava use?

In this second episode of our learning Kotlin series, we talk about Kotlin’s support for static members or … lack thereof. Kotlin as a language was designed so that there’s no such thing as a “static member” in a class but there are times when having static members can be useful.

So what do we do in those cases? do we just avoid static members? are there better alternatives? what are the costs with some of these approaches?

How are these resolved from a Java class when there's potential a name clash? What are some other gotchas and learnings from using properties? Listen on to find out:

046: okJesse - A deep discussion on okHttp, okio and Retrofit

contact@fragmentedpodcast.com (Spec) — Mon, 20 Jun 2016 03:00:00 +0000

Everyone loves Retrofit & okHttp. But how did they come about? Why ok? What was the need for such libraries? We went knocking on the doors of Square trying to find the answers to these question. We were lucky cause we found probably the nicest most brilliant Android/Java developer of our times - our good friend Jesse Wilson and without surprise, he crushes it!

He gives us the scoop on the origin stories of these amazing libraries and also gives us insight into okio and why it's such a game changer today.

045: Bluetooth (LE) with Dave (devunwired) Smith

contact@fragmentedpodcast.com (Spec) — Mon, 13 Jun 2016 05:00:00 +0000

We've always been curious about technology and the software surrounding embedded devices and the like. One such technology that's ubiquitous these days is Bluetooth (LE). In this show we talk with embedded technology expert and all round super smart AndroidDev Dave Smith a.k.a the wonderful devunwired.

We try to get a high level understanding of how Bluetooth works. From a developer's perspective, how does this tech work? Why should we as AndroidDevs be interested in this technology. What boundaries can we push? How can we effectively use this technology? In this episode we pick Dave's brain and try to answer some of these questions.

036: Working Remotely

contact@fragmentedpodcast.com (Spec) — Mon, 18 Apr 2016 05:00:00 +0000

In this mini Fragment we touch on a highly requested topic - working remotely. Donn talks about how to ease into remote working, tools for working remotely, tips and tricks for staying sane and productive while remote and he wraps it up by discussing the benefits employers have when hiring a remote workforce.

Show Notes

Remote work is best suited for information workers (programmers, designers, engineers, etc)
Read Remote by DHH and Jason Fried
- Great book that echoes what I feel about working remote.
- Tip: Listen to it on Audible, it's faster to consume.
How to ease into remote work at your current job
- Convince manager to allow a 1 day trial for one - three months.
- Remote day should be on Friday (fewer critical things happen on Friday, on average)
- After trial, if success, aim for 2-3 days of remote work. (Again, do this at the end of the week. Wed,Thu, Fri)
- Once successful, rally for full week of remote with an occasional in office visit (a day every week work two)

Staying sane while working remote

Donn's blog post on this topic
Create a work day schedule (5am-2pm, 8am-5pm, 10am-7pm, etc)
- When you're done, you're done. Leave work (your office/etc).
Schedule. Schedule. Schedule. Stick to a schedule.
- Get up at the same time
- Get dressed for work (no PJ's etc)
- Do your hair.
- Be presentable
- This is all mental
Prepare for the day
- Get coffee/tea/water and snacks
- Try to limit the opportunity of distractions
During the day
- Take a lunch, away from your desk.
- Go out for lunch with someone (significant other, friend, etc) at one to two times a week.
- Work out of the house a couple times a week, this increases our creativity.
Outside of Work
- You need social interaction, Cabin Fever is a real thing.
- Exercise 3-4 times a week if possible.
- Group classes are perfect for this.
  - CrossFit
  - Martial Arts
  - Yoga
  - Pilates
  - etc
Communication When Remote
- Put 3x-4x more effort into communicating than previous. You're not visible seen so you need to be more vocal.
  - Call
  - SMS
  - Blow up the Slack/Hipchat channel/etc
  - Objective - Clear your own path

Tools

For remote to work effectively, everything should be considered remote. If one employee is remote, then all meetings should occur as if the team is remote. This ensures that everyone can work effectively without missing anything.
Communication
- Group Chat
  - Slack
  - HipChat
- Video Chat
  - Google Hangouts
  - Skype
  - Join.me
  - Zoom.us
- Task Management
  - Trello
  - Jira
  - Asana
  - GitHub

Remote for Employers

Benefits from Remote workforce
- Much larger talent pool than the exhausted pool (or non-existent one that local). Higher quality employees/contractors/consultants for the same overhead.
- Remote creates much more loyal employees. You're giving them their life back and this is reciprocated.
- Your company becomes anti-fragile as you're able to adapt with the industry faster. You can hire in areas others cannot.
- On average, remote employees work harder and are more productive than their office counterparts.
- Less overhead! No need to pay for additional office space.

Show Notes

Effective Java (2nd Edition) - Joshua Bloch

Obey the general contract when overriding equals

When to not override equals:

Each instance of the class is inherently unique.
You don't care whether the class provides a "logical equality" test.
A superclass has already overridden equals, and the superclass behavior is appropriate for this class.

The equals method implement an equivalence relation which states it must be:

Reflexive
Symmetric
Transitive
Consistent
For any non-null reference x, x.equals(null) must return false.

A recipe for a high-quality equals method is as such:

Use the == operator to check for references to this object.
Use the instanceof operator to check if the argument has the correct type
Cast to the correct type.
Check all field types and corresponding field types.
Finally, when done, ask yourself - is this method symmetric, transitive and consistent?

Caveats

Always override hashcode when you override equals
Don't be too clever!
Don't substitute another type for Object in the equals declaration.

025: Effective Java for Android developers : Item 7

In this mini Fragment, we introduce Joshua's seventh Item and a momentous end to the first chapter: Avoid finalizers

Stay tuned for more items from our "Effective Java for Android developers" Fragment series.

Show Notes

Effective Java (2nd Edition) - Joshua Bloch

Avoid finalizers

If you don't know what they are, ignorance is bliss. If you know what they are, avoid them!
Finalizers in Java != destructors in C++ (C++ counterparts to constructors).
In C++ destructors
- you reclaim resources here (Java has GC)
- you also reclaim non-memory resources (use the try-finally block in Java)
(unpredicatable amt of time between object becoming unreachable and finalizer being executed) Never do anything time critical in finalizer!
- System.gc + System.runFinalization increase chances - no guarantee
- System.runFinalizersOnExit + Runtime.runFinalizersOnExit are the ones that do - but they are fatally flawed
Java 7 has try with resources, which is also interesting and auto-closeables. [Android] devs can only dream of these.
If an uncaught exception is thrown in a finalizer, it is ignored, and the finalization abruptly terminates.
Severe performance penalty for using finalizers - (one e.g.) time to create and destroy simple object goes from 5.6ns -> 2400ns
Only valid use: as a safety net or to terminate noncritical native resources.
[Android] you're probably better off using Android's lifecycle methods.

019: Effective Java for Android developers : Item 4

contact@fragmentedpodcast.com (Spec) — Thu, 15 Oct 2015 06:58:00 +0000

Singer and Android developer Donn Felker explores Joshua Bloch's fourth Item: Enforce noninstantiability with a private constructor.

Stay tuned, cause we got more of these quick ones coming.

Effective Java (2nd Edition) - Joshua Bloch

Enforce noninstantiability with a private constructor.

Examples where you don't want class to be instantiated

class that groups static methods and static fields (Util like classes think java.lang.Math/java.util.Arrays)
class that groups static methods (including factory methods) for objects implementing specific interfaces (think java.util.Collections)
class that group methods on a final class (vs. extending the class)

Considerations

Makes no sense to instantiate such "Util" classes
Private constructors prevent instantiation
Important side effect: prevents subclassing

018: Effective Java for Android developers : Item 3

contact@fragmentedpodcast.com (Spec) — Thu, 8 Oct 2015 17:49:00 +0000

In this mini Fragment, we introduce Joshua's third Item: Enforce the Singleton property with a private constructor or an enum type.

Stay tuned for more items from our "Effective Java for Android developers" Fragment series.

Show Notes

Effective Java (2nd Edition) - Joshua Bloch

Enforce the Singleton property with a private constructor or an enum type

Approaches

Create a public static final INSTANCE variable and privatize constructor
Same as 1 but privatize variable and expose access with provide factory method getInstance
Single element Enums

Considerations

First two approaches are open to Serialization attacks (deserializing creates new instance)
To protect from those declare the fields transient + provide readResolve method
Enums are concise, provide free serialization and ironclad Singleton guarantees and are functionally equivalent to first approach

Show Notes

Effective Java (2nd Edition) - Joshua Bloch

Consider a builder when faced with many constructor parameters

Patterns available for constructing object with parameters:

Telescoping Constructor Pattern - Provideconstructor with only required parameters, another with a single optional param, a third with 2 optional params... and so on.
- Advantage: Works well for small number of parameters
- Disadvantage: Does NOT scale well
JavaBeans Pattern - Callparameterless constructor to create the object; then call setter methods to set required parameter and each optional param of interest.
- Advantage: Scales well, easy (but wordy) to read resulting code
- Disadvantage: Allows inconsistency (if all required params not called); impossible to make classes immutable if using this pattern.
Builder pattern - winner!
- Advantage: Simulates named optional parameters; allows immutable objects to be constructed; flexible
- Disadvantage: more ceremony to actually construct the Builder Class and finally use.

Example usage from Android source:

AlertDialog Builder [androidxref.com]

Tip:

Use IntelliJ to generate your Builders easily

014: Effective Java for Android developers : Item 1

contact@fragmentedpodcast.com (Spec) — Mon, 10 Aug 2015 11:30:00 +0000

We've mentioned the book "Effective Java" by Joshua Bloch quite a few times on previous episodes. At this point, everyone knows they should have read this book (quadruple times). But it's a dense read and everyone could use a reading buddy. Also, what does Effective Java look like through the eyes of an Android developer?

In this second installment of our Fragment (a.k.a mini-episode), we thought we'll do our listeners a favor and help with that reading. We introduce the very first of these venerable "Items": Consider providing static factory methods instead of constructors.

Stay tuned for more items from our "Effective Java for Android developers" Fragment series.

Show Notes:

Effective Java (2nd Edition) - Joshua Bloch

Consider providing static factory methods instead of constructors

static factory method makeText for Toast class [androidxref.com]
ObjectAnimator [androidxref.com]:
- .ofInt [androidxref.com]
- .ofArgb [androidxref.com]
- .ofFloat [androidxref.com]

Advantages:

You can control the name and thus give it much more meaningful names
You are not required to create a "new" object each time they are invoked
You can even return an object that's a subtype of the return type (unlike constructors which only return class type)

e.g. Java Collections framework [grepcode.com]

Disadvantages:

Classes without public or protected constructors cannot be subclassed
Static factory methods are not readily distinguishable from other static methods

Takeaways

"Consider" using static factory methods (not always)
Use newInstance when creating Fragments [androiddesignpatterns.com]
Use newIntent static factory method for creating intents inside the target activity.

012: Continous Integration and Collective Code Ownership

contact@fragmentedpodcast.com (Spec) — Tue, 21 Jul 2015 18:09:00 +0000

In this episode we're trying something new. Everyone has requested more episodes of the podcast. In short, everyone wants a weekly show. So this week, we're introducing what we call a mini-episode ... or as we like to call them a "Fragment". Fragment episodes will be shorter in length but still packed with goodness. They will range from ~7-25 minutes in length and will showcase either Kaushik, myself (Donn) or both of us.

In the first "Fragment" installment we're going to talk about Continuous Integration (CI) and Collective Code Ownership (CCO). Donn talks about what CI is, why its important and how it benefits you and your team. He then dives right into CCO and how it can be facilitated through testing.

We hope you enjoy these new mini-episodes ... aptly named ... Fragments. :)

008: Pocket Casts Amazingness with Philip Simpson

contact@fragmentedpodcast.com (Spec) — Tue, 19 May 2015 11:24:00 +0000

In this episode, we talk to Philip Simpson, one of the rockstar developers of the amazing Pocket Casts Android Application. We learn about how Philip and his partner, Russell, started Shifty Jelly and how they grew their team from a two-person shop to a small staff all while creating one of top apps on Google Play, Pocket Casts. We also talk about some of the tools, tips and tricks that they've used to help them scale, grow and become more effective as indie app developers. We eventually hop into some deep talk about audio software and all kinds of tech in general. If you've always wondered what it takes to be an indie app developer then this is the episode for you - Philip does not let us down.

In the final part of this two-part segment, we continue our talk with Jake Wharton. We dive right into the topic of testing. Jake then talks about his approach to testing apps in Android and the different languages that he finds interesting. We then move on to RxJava, NotRxAndroid, SqlBrite and many other libraries and topics to round out this great second episode. Again, we'd love to thank Jake for joining us here on the Fragmented Podcast show; it has been an honor. We hope you enjoy it as much as we did.

005: Image libraries for Android

contact@fragmentedpodcast.com (Spec) — Fri, 17 Apr 2015 14:20:00 +0000

In this episode of Fragmented, Donn and Kaushik start off by discussing the tips and tricks available for efficiently loading images in an Android app. Good image libraries make use of these techniques and perform all the heavy lifting in the background. So they then discuss the different image library options available for Android developers.

Show Notes

Techniques/tips on effective image rendering in Android:

Bitmap sizes and allocation:

Displaying bitmaps efficiently [developer.android.com]
RGB_565, ARGB_888 and other different bitmap configurations[developer.android.com]
Android Camera2 apis [developer.android.com]
Chet Haase DevByte : Bitmap allocation [youtube.com] (bitmaps managed in Dalvik heap post 3.0; so large bitmaps implies large heap implies GC could happen more often)

Reuse bitmaps:

inBitmap option for Android 3.0 and later [developer.android.com]
before Android 4.4 only equal sized bitmaps with inSampleSize 1 supported[developer.android.com]
Reusing bitmap objects on Android[booking.com]

Downsample bitmaps

Load a scaled down version into memory [developer.android.com]
- see code for calculateInSampleSize

Caching

Cache Algorithms - see LruCache [wikipedia.org]
LruCache object in Android [developer.android.com]
JakeWharton DiskLruCache [github.com]
Don’t use Soft or Weak References for your Caches [developer.android.com]
Android Performance Pattern DevByte - why 60fps [youtube.com]

Image libraries for Android:

Picasso by Square [github.com]
- fetch introduced in V 2.5.0 (Changelog) [github.com]
- Picasso doesn’t do bitmap recycling
- Jake Wharton’s thoughts on Picasso not having a bitmap pool [github.com]
Glide [github.com]
- github issue where author explains tags being used to store metadata[github.com]
- Glide does bitmap recycling
Ion
- DeepZoom with Ion [youtube.com]
- Uses BitmapRegionDecoder to implement DeepZoom[developer.android.com]
Volley
- Ficus Kirkpatrick introduces Volley in Google.IO [youtube.com]
- Doesn’t come with an image caching mechansim out of the box[stackoverflow.com]
Fresco

In this episode of Fragmented, Donn and Kaushik continue their conversation with Dan Lew on RxJava. In the final part of this 2 part series, they talk about many useful RxJava operators and other intricacies of using RxJava in Android.

Show Notes

RxJava Operators:

Observable.just [reactivex.io]
Observable.from [reactivex.io]
Observable.defer [reactivex.io]
- Using defer to handle “Old, Slow Code” [blog.danlew.net]
Observable.map [reactivex.io]
Observable.flatmap [reactivex.io]
- map vs flatmap (alchemist and cheese shredding analogy [reddit])
Observable.zip [reactivex.io]
Observable.combineLatest [reactivex.io]
Observable. switchMap [reactivex.io]
Observable.distinctUntilChanged [reactivex.io]
Observable.lift explanation [reactivex.io]

Hot vs Cold observables - From the RxJs wiki [github.com]

uses js instead of java, but concepts are the same and this is the best explanation I’ve found so far.

RxJava wiki on Backpressure [github.com]:

Ring buffer size: System.setProperty("rx.ring-buffer.size", "128");
Issue with changing buffer ring size [github.com]
It’s 16 on Android, down from 1024 originally. :P So it’s actually 64x smaller.
