Getting crash on build() method:

GPlayMusic api = new GPlayMusic.Builder().setAuthToken(authToken).build();

When running on Android Phones with OS versions below Nougat as 'build()' method contains following code:

Optional optional = gPlay.getRegisteredDevices().toList().stream()

and java 8 streams are available from Android Nougat.

i am aware of that problem, but this library is using quite a lot of java8+ dependent code and i have no plan to change that.

You could try to use Retrolambda or force the compiler to emit java7 bytecode (https://stackoverflow.com/a/22610424) to create a java7 compliant version, but i am not sure how good the result will be.
