In this episode of Fragmented, Donn digs into three things that every Android developer needs to know.
In this short fragment, Kaushik explains how you can trace network requests from your app by adding a special header. Easily trace an HTTP request all the way from a client to your backend web process.
In this episode, Donn and Kaushik talk about productivity tools for developers. As developers, what are some additional tools and utilities that really up your game. If you wanted to see how they tweak their development environments and workstations in general, this is a good episode to listen. Also introducing a Fragmented Discord Chat server!
In this mini fragment, Donn and Kaushik share some thoughts on real world testing with Android development - a favorite topic of theirs.
Kaushik recently ran into a case where an espresso test fails because the UI stops performing. It's an interesting discussion on figuring out what matters when you write your tests. They dive into strategies and techniques around testing. What makes a good test, what should you be testing?
They then talk about why Hermetic testing is pretty hard on mobile and ideas around a simple solution that could be provided out of the box. They then round it up talking about TDD and it's role in today's world.
In this mini fragment, Donn and KG talk about Impostor syndrome. Most of us developers are plagued by this. Does this feeling ever go away? How do we deal with this? Listen to this short episode to find out more.
We all know of ProGuard, we want to use it and like it. But let's face it proGuard ain't pretty. In this episode we have Jeb walk us through the magic of ProGuard.
We talk to Jeb Ware of American Express. Jeb works as an Android developer and has given some great talks on ProGuard. He walks us through what ProGuard is, how it works, advancements with R8 and more.
By the end of this episode, you should have a new found appreciation for proGuard and bravely approach adding proGuard to your projects.
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.
In this mini fragment, Donn asks KG about a recent hackathon side project that he worked on with Kotlin scripting.
We go into kotlin scripting (using kscript), pros cons, setting it up and more. We've added links some interesting resources, so you want to make sure you check out the shownotes for this one, so you too can explore kotlin scripting and see if it's a fit for you.
In this episode, DF and KG decompress. They start off talking about ideas around KISS vs DRY in software engineering. They move on then to talk about a dear topic - functional vs unit testing and then dive into some of the woes of having a testing infrastructure spun up. Also announcing our youtube channel !
In this fragment episode, Donn talks about Kotlin extension functions. He discusses what they are, how to build them, why they're useful, how to organize them, visibility and how to call them Java and much more.
Donn's on a roll again this week and talks to us about his experience having developed Android for a while. In the early days of Android development, as app developers we felt like we had a decent grasp of everything you needed to know to pump out decent apps.
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.
Donn gives his 2 cents on this subject.
In this episode, Donn talks about how you can get effective help with your coding problems with an SSCCE - a Simple, Self-Contained, Correct (Compilable), Example.
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.
In this mini fragment Kaushik talks about dealing with the Money object. With money we need decimals, but the obvious solution of using a float or double may not work as advertised. Listen to this episode to find out why and how you can go about dealing with this.
We live in a time of booming AR (and VR). We wanted to talk to someone who’s worked with it and would know a thing or two about the subject. Then we found Yuliya – also known as the walking wizard of ARCore. In this episode, she teaches Kaush and Donn about ARCore, the differences between AR/VR, the fundamental building blocks of ARCore, some of the newer concepts introduced like Sceneform. An action packed episode to say the least. Listen on !
In this episode, we resume our conversation with Airbnb's Gabriel Peal. If you haven't listened to part 1, you really really should go back and do that. In that episode, we kicked it off by first trying to understand the goals and the story behind why React Native was chosen as the code sharing technology/tool.
If you haven't heard, Airbnb has decided to move away from React Native. Friend of the show Gabriel Peal wrote an in-depth series of blog posts about this. We had so many questions around this that we asked him to come on the show and he graciously accepted to answer some of our questions.
It's always a pleasure listening to his insights and this episode is no exception!
In today's episode, we are joined by Sam Bobra - engineering manager @VSCO, android fangirl and gRPC magician (some would go so far as to say evangelist !) to talk about gRPC on Android. Super informative episode!

In today's episode, we sit down with Caren Chang from June to talk about audio engineering for Android. More specifically, how stoves can use audio to send notifications.
In this episode, we continue with Part 2 of this GraphQL series. If you haven't listed to episode 125 already, it might make sense to first listen to that one cause we go into the basics of GraphQL.
In this episode, we dive into the specifics of Apollo and how Mike went about creating a GraphQL client for Android. Let's get on with Part 2.
In this episode, we talk about GraphQL. Friend and GDE Mike Nakhimovich helped create the library Apollo for Android, which is the defacto official GraphQL client for Android.
In this first part of two, we take a step back and first try to understand what GraphQL is, why one would use it, how Mike set out to create and contribute Apollo for Android and his journey and satisfaction with open sourcing it when he worked at the New York Times.
If you've ever been interested in GraphQL, this is a good show to get you up to speed.
In this episode of Fragmented, Kaushik talks to Chiuki & Huyen from Android Dialogs and Russell & Philip from Pocket Casts. Fresh after IO we huddled in a room to talk about our first impressions and what we thought were some of the highlights for us Android developers. Hope you enjoy the show! (if you want to see a behind the scenes crossover special, make sure to subscribe to Android Dialogs!)

With good –most of the time– also comes the bad. In this episode, Kaushik and Donn chat about the small annoying things about being an Android developer, or more aptly - "Micro Frustrations".
We usually cover the new, latest, greatest and awesome developments. But it helps to step back and also point out the things that are broken and the 1000 cuts so to speak.
Sit back and enjoy this hearty rant!

In this episode of learning kotlin, we look at the
typealias keyword. The
typealias keyword allows you to provide alternate names for existing types and and function types. Learn how, why and when you can use it in this episode
In this episode of Fragmented, we wrap up another 2 part series. We dive into the details of the Arrow library with this one. Arrow is a library in Kotlin that helps bring many of the functional paradigms of programming to your daily development. We talk to the team about how it all started, the history of the library, why we even need arrow, how Arrow is structured, some of the pitfalls, and in the end some resources on getting us started with Arrow.
In this episode of Fragmented, we kick off another 2 part series. This time it's with the Kotlin Arrow team! In the first part, we talk to Jorge, Raul and Paco about Functional programming in general, some core FP concepts, do we already use functional programming today, what are pure functions, do I need to know complicated math to do FP, Immutability, Referential transparency and so much more. These are all pretty daunting words, but the Arrow team break it down and make it really simple for us to understand.
In part 2 of this series,
To help us understand Flutter in-depth we talk to Flutter's GDE Eugenio Marletti. In Part 2 of this 2 part series, Eugenio helps us understand what flutter is, why it was created, how it works, some really cool features with Flutter and why an AndroidDev today should really give Flutter a good look.
We got so carried away in conversation, that we were forced to break this episode into two parts. If you missed part 1 but want to go back and listen you'll find it here: 118: Flutter and cross-platform development with GDE Eugenio Marletti - Part 1
In this episode, we dive into one of our most requested topics and highly anticipated ones - Flutter.
To help us understand Flutter in-depth, we talk to Flutter's GDE Eugenio Marletti. In Part 1 of this 2 part series, Eugenio helps us understand what flutter is, why it was created, how it works, some really cool features with Flutter and why an AndroidDev today should really give Flutter a good look.
We got so carried away in conversation, that we were forced to break this episode into two parts. Stay tuned for Part 2.

In this episode, Donn and Kaushik sit down to talk about multi-module builds with Gradle. They talk about how you can separate your build into multiple different modules and how you might go about implementing it.
In this episode of learning kotlin, we look at 3 important keywords - inline, noinline and crossinline. The inline keyword is super common and you've probably run across this one at some point. What does it mean and when is it useful? We also look at the related but seldom used variants noinline and crossinline.
In this episode, we talk about the different parts of Android architecture components. We've had episodes on Room and the paging library, so in this one, we thought we'll touch a little on Lifecycle Owners & Observers, ViewModels, and LiveData. Akshay Chordiya helps break it down. Listen on!
In this episode, we talk to Patrick Nikoletich from Microsofts App Center team. We explore the intricacies of the Continuous Integration server system on the App Center platform.
In this episode we catch up with a highly energetic but sick Christina Lee about the delightful details in the Pinterest app, delving with the dark side (Swift), giving live coding presentation talks and touching on some Kotlin details like covariance and contravariance. Listen on for a power-packed 40 minutes.
In this mini-fragment episode, Donn talks about Item #9 of the Effective Java (Third Edition) book - Prefer try with resources to try finally.
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.
In this mini-fragment episode, Donn talks about Item #5 of the Effective Java (Third Edition) book - Prefer Dependency Injection to Hardwiring Resources.
In this episode of Fragmented, we talk about CI, CD and CD services. That's Continuous Integration, Continuous Delivery, and Continuous Deployment.

This is the 100th episode of Fragmented. We do things a little differently for our 100th episode and field a bunch of listener questions that came in. We're going a little meta and talking about our experience starting Fragmented, our process, how we pick guests and topics, our setups, our favorite Android libraries and classes (?!).
Thank you so much for being a listener. We cannot express how grateful we are to have you.
In this episode, Donn talks about Item #17 from the Effective Java book: Design and Document for inheritance or else prohibit it. Learn how you should be documenting your code that is built for inheritance when you should not call overridable methods and much more.
In this episode, Donn is at Droidcon NYC 2017. He sits down to chat with Dan Kim about Kotlin, Gabriel Peal about React Native, Scott Alexander-Bown about Android Security, Jose Alcérreca about the Android Architecture Blueprints and Kevin Galligan about the history of Droidcon NYC and his new library - Doppl.
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.
In this episode, Romain Guy from Google gives us the lowdown on a bunch of Hardware related stuff.
He starts off by explaining how the refresh rates on screens matter, what it would mean to have something like a 120Hz display for Android screens, how things like V-Sync and double buffering work, using different screen technologies, how much work is done by the CPU and GPU and so much more.
This was one of those episodes where we tried so hard to hold back for fear of recording for another 2 more hours. Romain is clearly one of the most knowledgable and interesting engineers to talk to today in the hardware land of Android. What a blast!
In this episode, we talk to Florina from Google about the recently released Database library Room. Room was introduced as part of the Android Architecture components and has been picking up a lot of steam in the community.
Room focuses on being a beautiful api layer to Sqlite. Florina explains to us how we can use Room to create a database, creating entities and how them map to tables, using DAOs to access data and even observe them
Listen on for the details!
In this episode of Fragmented, Donn talks about a common problem almost all software engineers face in their career - Design Patternitis.
In this episode of Fragmented, our friend and RxJava paragon of the Android - Dan Lew, returns for a record 3 and 1/2 time.
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?
Listen on to find out more!
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?
Listen on to find out more!
In this decompress episode, DF and KG kick it off with a brief discussion of the highlights from the recent reddit AMA that the Android Engineering folk conducted. What were the interesting things they learnt or were surprised by etc.? They then go on to briefly discuss two topics they've always chatted about (off-air) packaging by feature (not layer) and most recent thoughts on testing. Listen on to find out more:
At I/O '16 Google announced the super cool new feature "Instant Apps". It's only at this IO, have we started to see real world examples and third parties pull off this feature.
In this episode, we talk to GDE Zarah Dominguez who's company "Domain" was one of the partners for this program.
What is the Instant Apps feature? What are some usecases where this comes in handy? How does it actually work internally? What does it take for a developer to implement this feature in their own app? Listen on to find out!
In this mini Fragment, KG talks about his journey learning Kotlin as a newb. Given that Kotlin is most likely going to be the de-facto language for most developers, it makes sense to deepen our understanding of the language (as we have strived with Java over the years).
"Properties" in Kotlin are a first class language feature. But what does that actually mean? What are the nifty features we get with properties? 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:
In this episode of Fragmented we talk to our friend Piwai from Square.
Piwai's a pro at testing and breaking apps (he built LeakCanary - so not terribly unexpected). He teaches us some strategies on debugging app crashes and briefs us on this concept he calls "offensive programming" which has helped him a lot with his Android development.
It's good stuff and we hope you enjoy the show.
In this mini-Fragment episode, Donn talks about Item #16 of the Effective Java series - Favor Composition over Inheritance. You'll learn why using inheritance is not always a great idea and how you can use composition in place of it to make your code more anti-fragile, resilient and clean.
In this mini-Fragment episode, Donn talks about Working Effectively with Legacy Code. He doesn't just talk about the book itself, but he talks about how to approach a legacy code base and start delivering value as soon as possible, yet with confidence. If you've recently started a new job, moved to a new team, started working on an existing code base, then this episode is bound to help you.
In this episode, we talk to Dan Kim about Kotlin. Dan is an Android developer at the company Basecamp and has some great Kotlin posts on the company's famous blog Signal Vs Noise. He was pretty early, on the Kotlin train and has been working with the new language for quite sometime now.
Instead of trying to go into every single detail about Kotlin, the nuances of the language, it's syntax etc. we take a more general approach and talk about starting out on Kotlin, how does on go about migrating an Android codebase to Kotlin, what are things we should watch out for when using the language. This and a whole lot more!
This was truly one of the most memorable IOs Google has ever conducted. In keeping with tradition, Donn and Kaushik talk with a bunch of awesome #AndroidDev and get their opinions/thoughts on IO and Android in general. As always, these are super fun episodes.
