Original GitHub issue: https://github.com/devgianlu/librespot-android/issues/11

It seems that the player gets stuck here:
github.com/devgianlu/librespot-android@3278d3db61/app/src/main/java/xyz/gianlu/librespot/android/MainActivity.java (L184)

Internally librespot-java uses a CompletableFuture which may not be supported on Android 6, even with desugaring.

Hmmm, this might be an endless game. But maybe it's simple to solve? As said, i don't know what's worth the effort and what not.

I could also write an hackish piece of code that checks if the player is ready in a loop, but I think your solution would be better because the same issue could appear in other parts of the code.

I would rather shy away from using retrofix. It is too hacky for my taste. I have this nagging thought of "why is Google not backporting completeable futures and the likes?" -there might be subtleties not easy to get right. Android 7 support is already great from my point of view.
