In this episode, Donn talks about Kotlin Lambda Expressions. He explains the syntax and how to build a couple of simple lambda expressions with and without type inference and declaration. We wrap up with a small example of passing a small lambda with multiple values to a function. See the show notes below for more info. This is part 1 of a multi-part series on Lambda Expressions in Kotlin.
In this episode, you’ll learn all about Kotlin Sealed classes. Donn walks you through what they are, how to create them, how to use data classes, objects and regular classes to create a restricted type hierarchy.
In this episode, Donn talks about Item #20 in the Effective Java book (third series) by Joshua Bloch. He discusses why you should think about using interfaces over abstract classes, how they can add mixin like behavior to retrofit existing classes with new behavior, default methods, skeleton implementations and more.

With the release of Android Q we now have the settings panel and all its glory. This panel, while most likely overlooked as a minor feature, is actually a diamond in the rough.
Why?
Simply because it’s going to lower the abandonment rate of your app and increase the engagement of your app at the same time. Donn talks about this in depth in this episode.

Growing as a developer is important for you, your career and your future. One of the best ways to grow your career is to start writing.
Donn recommends starting a blog or contributing to a blog. The process of writing will expose your weak points in your comprehension of a topic. Refining your communication skills through writing and putting thoughts out into the universe via a blog will broaden your skills as a developer.
Ultimately, writing is about communication and communication is the cornerstone of success in much of anything. In this episode, Donn walks you through why you should start writing to help you grow as a developer.

In this short fragment episode, Donn explains how you can clean up your RxJava 2 streams and ensure no memory leaks are occurring by using the AutoDispose library from Uber.
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 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.
Hope you enjoy this one!
