Serenity for Android 1.9.0-M1 is available for testing. There are a lot of under the hood changes happening in the 1.9.0 branch. So plan on seeing multiple milestone releases for this one. If you use Serenity for music playback, please check this version out, as I did end up touching portions of that code. No new functionality here, just migrating to using Dagger for a dependency injection framework, and getting things setup so I can migrate to using the new RecyclerView and possibly some of the new Android 5.0 features for the ADT-1 and Android TV devices.
You can find the latest development version for testing at the link below.
