Player Occasionally Crashes on Bluetooth Disconnect #91

Closed smithdtyler closed 9 years ago

smithdtyler commented 9 years ago

To replicate: turn off bluetooth headset while playing. Player continues playing and the GUI is largely unresponsive.

Here's a log trace from the issue occurring:

In the non-error case, the "internal/external state mismatch corrected" is not displayed:

Sigh, looks like this is a common issue:

When the crash occurs, the app doesn't crash entirely. UI events keep getting passed to the playback service, which attempts to handle them but apparently fails to take action.

Adding some additional logging, I can see that the error causes the player to think it is paused when it isn't.

07-29 19:45:13.954  18480-18480/com.smithdtyler.prettygoodmusicplayer I/MyService﹕ Received start id 5: Intent { cmp=com.smithdtyler.prettygoodmusicplayer/.MusicPlaybackService (has extras) }

This error does not seem tightly correlated with the bluetooth headset itself, the headset disconnect is just the source of the message.

Perhaps I can just do a "pause" and catch the exception?

Just a reminder, I still experience this crash on Android 6.0 (Cyanogenmod 13) with Pretty Good Music Player 3.3.2.
