Cannot build my app after added the lib

[robsoncardozorebel]

After adding the lib I could no longer build my app only if I disable shrink and minifyEnabled. Anyone can help?

`FAILURE: Build failed with an exception.

• What went wrong:
  Execution failed for task ':app:minifyProdReleaseWithR8'.

Unfortunately, I don't have much experience with code minification.
Are you able to reproduce this with the example app within this repo?

Hey @robsoncardozorebel, did you made any progress regarding this library and code minification?

@lschmierer
add to proguard file
-keepattributes Exceptions, Signature, InnerClasses, LineNumberTable

@RationalEgoism thank you, will check it out later.
Can you elaborate what it does (how did you came up with these specific attributes to keep)?

Edit: Especially LineNumberTable sounds kinda specific to your project?
