065: Developer Platform engineering with Ty Smith

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.

Kaushik Gopal: I was talking to one of my colleagues who works on our iOS applications the other day. We started off the conversation talking about advantages and disadvantages of the different local database options—like Realm and SQLite.

Then he mentioned something that blew my mind. A parent-child relationship is a typical use case in any marginally complex system, and we were talking about how to model them in a local database. Then he said, “Yeah, you’ve got to be extra careful with those relationships. You don’t want retain cycles.” This sounded a lot like a memory leak to me, so I probed a bit further, and that led me to the idea behind this mini-Fragment episode: the world of garbage collection and reference counting.

Donn Felker: Today, I’m going to talk about Item #13 from Effective Java, by Joshua Bloch. For those of you who are just joining us, Kaushik and I are covering all of the items inside this book in relation to how they apply to Android developers. We’ve already gone through the first 12, so I’ll be talking about #13: Minimize the accessibility of classes and members.

Joshua puts this very well right out of the gate, so I’m going to read this verbatim:

062: Effective Java for Android Developers – Item #12: Consider Implementing Comparable

In this mini-Fragment episode, Donn talks about Item #12 of the Effective Java series – Consider Implementing Comparable. You’ll learn about how you can use the Comparable interface to give your code the extra sorting boost it needs. Work with Arrays.sort(), Collections utilities and even sorted data structures.
