I still doesn't understand why people choose to use RxJava (Kotlin in this case), I'm not here to start a flame war, b/c I really never used it but read some articles about it and didn't found it useful or easy to use

@norman784 Rx is really usefull when you have a data stream and need to tranform this data (moreover transform it in background)

selfishly, it makes jumping between threads, synchronizing actions, and managing lifecycle dirt simple once you get past the rx syntax

you've probably set up an observable pattern in an app before, Rx just provides a standard API around that. it might not seem worth it for simple scenarios, but once your data flows become non-trivial, it really helps to think of your problem within the framework

It also makes async operations easier to orchestrate
