Fragmented - Android Developer Podcast

We kick off 2017 talking to Uber Engineer Gautam. In first part of this 2 part series, Gautam talks to us about the Uber Android app, the complexity in the architecture, the scaling challenges, the pain points Android developers faced working on such a massive app. He then goes on to explain how his team (Android Developer Experience) at Uber have approached these challenges and come up with elegant solutions. We then dive head deep into Buck - the build system for Android development, it's advantages and the benefits that the folks at Uber have observed having migrated.

In this episode, Donn talks with Xamarin cofounder on how one can use Xamarin for Android development. They start off chatting about using Xamarin just for business logic sharing. This Joseph tells us was the original intention for use. They also touch on Xamarin forms which allows you to additionally build UI elements cross platform. Even if you don't use Xamarin or plan to use Xamarin right away, this was a fantastic insight into the platform, from the creators directly. They touch on advantages, how to really leverage the platform and potential downsides.

In this episode we talk to Ty Smith about all things Developer Platform. Currently a tech lead at Uber, Ty has quite the illustrious career having worked on some of the biggest names you've heard like Uber, Twitter(Fabric), Evernote, Zagat etc. Unlike regular client app development, Developer Platform spans a variety of interesting topics like building consumable SDKs, building libraries with good APIs, creating Android integrations and App to app communication via components like Content Providers, AIDL Integrations, Intent APIS and deep links. We ask Ty how he got started in this field, how one should go about thinking about it and the interesting challenges that one would run across in this intriguing field.
