Check if Android correctly handles play/pause for BT devices

User report:

```
I have a 2019 audi e-tron where I use android auto to play pocketcasts.

When I use youtube music, I'm able to pause and unpause the music with the steering wheel button. However, with pocketcasts, I can only pause it. It does not resume playing when I press the button again on the steering wheel; I have to resume playback by pressing a button on the screen.

No Android file or test is named. Start by locating the Android Bluetooth or media-session remote-control entry point, then compare its play/pause handling with the iOS behavior quoted here and reproduce the reported steering-wheel interaction; done means the button can pause and resume Pocket Casts playback.
