Fragmented - Android Developer Podcast

In this episode, we talk to our friend Matt Logan. Matt took some time off and worked on an indie app called Sessions. He built this for both Android and iOS. In this episode we talk to him about his experience building apps on both platforms, techniques, advice and other good stuff.

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?

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. 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.

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. Download Contact @fragmentedcast [twitter.com] @donnfelker and +DonnFelker @kaushikgopal and +KaushikGopalIsMe

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. Using an SSCCE provides others with a quick, concise way to examine the problem without extraneous libraries, UI toolkits and various other parts of your application that do not matter to the problem at hand. Donn breaks down each component of the SSCCE so you can wrap your head around what you need to get help quickly.

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. Show Notes Danny's slides (DI in a Kotlin world) talk Koin Toothpick how to pronounce reified Service Locators vs Dependency Injection Your application is aware it's using a Service Locator, but your application should be totally un-aware that it's using a Dependency Injection Container.

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. After two years, 220 screens, and 120,000 lines of javascript, Gabriel tells us why they're moving away from React Native.

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 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.

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.
