This tries to control the last player that played a (new) song.
It is very limited since we cannot get the source of an intent.
Instead we try to guess from the Action.
The problem is that we cannot support players that use only the action "com.android.music.XXXX" and not something own.
Also try to blindly support getting spotify metadata (for testing #112)
- model package contains mostly shared interfaces (UI+service), not named GB*
- impl package contains implementations of those interfaces, named GB*
the impl classes should not be used by the service (not completely done)
- the service classes should mostly use classes inside the service and deviceevents
packages (tbd)
Every device now has two packages:
- devices/[device name] for UI related functionality
- service[device name] for lowlevel communication
