Drawables need to be defined in the app module, which has the vector
compat library enabled. When enabling the library for the core module,
the app breaks on API 19.
The lock button controls whether tracks in the queue can be reordered
and swiped. Since swipe works regardless of the "keep sorted" setting,
the button to disable swipe should always be available.

context menu open. Pressing items crashed the app.
