Music player for Android

The release variant is signed in a special way. You need to create a file called signing.properties and place it in the app folder. The content of the file must be like:

storePassword=pass1243 keyPassword=pass1243 keyAlias=debug storeFile=../app/signing/debug/debugjks.jks 

This is just a stub and of course you can use you own keystore.

• The code is divided into modules, but there is still a lot of code in the app module. At least implementations from the di package could be moved.
• Change the player implementation: currently android.media.MediaPlayer is used as the engine, which has many issues and limitations. Worth a try ExoPlayer or something.
• Application consumes a lot of memory at runtime.
• Headsets are just... argh!!! Just need to implement a normal handler that will handle clicks for all headsets.
• A lot of the code is still in Java. Need to rewrite in Kotlin.
