Fragmented - Android Developer Podcast

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. 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 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.

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 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 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. They discuss build performance with incremental compilation, isolation of features, code ownership and how to handle cross-cutting concerns like persistence and networking.

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.
