Hardly Comprehensive Introduction to RxJava: Observable Types, Backpressure, and Error Handling

RxJava is an ever increasing-in-demand tool for developers of many platforms even beyond Android.

Getting Started with Firebase Performance Monitoring on Android

We are on the LAST installment in our ‘Getting Started With’ series and it is on performance monitoring! Now there’s a reason why this was the last for me to cover, and probably the last that many of you would pay attention too (but please, correct me if I’m wrong).
