Generating a signed build using Android Studio Arctic Fox version 2021.3.1 seem to be a tricky thing to do. I spent several hours just to figure out where the issue is and at the end, I still don’t know what is the exact reason for signing to not work.

Recently I played around with the integration of Google Cast inside Exoplayer and I was really amazed to see how bad it is and how much it sucks. I decided to write this post with the idea it will help someone else who is also struggling with the Google Cast integration for exoplayer.
Requirements
So the requirements I had for the integration of Google Cast are quite simple:
- Play an item on cast
- Play a list of items – when you press Next you go to the next item
- Forward / Backwards with 30 seconds – so you can skip through the track
- Play / Pause support
- Switch between lists of items – you can player item 2 of List A, you should be able to switch to item 3 of List B
- Switch between phone playback and cast playback – switch from cast to app and from app to cast
- Update the progress when casting – time elapsed should also be updated
- Volume up/down are supported
Migration from Gson to Moshi – small tricky parts

Recently I played around with a library that is used in multiple projects. This library has a huge list of dependencies like: coroutines, rxjava, navigation library from Google, material library, custom edit texts that come from 3rd party libraries and many more. Basically this library has also a rich set of screens available to the users that open given certain conditions. But our issues was bigger.

The RxJava approach
I am currently working on an app where the devs before me took this strange decision in regard to the refresh token mechanism – have a single entry point of the app which is called every time whenever you need to have a fresh token. What I mean is this:

Problem
Each Android app has an authentication mechanism or at least most of them do. What this auth mechanism does is that it refreshes an access token using a refresh token every N minutes. In our case these N minutes are 7. And now the question is: How do I implement this?

Testing data classes in Kotlin
As we all know, data classes are final by default on Kotlin and if you try to use Mockito and mock such a class, you will get an exception. What you need to do is add this file:
