QUESTION: Fake Media Player

[ricardojlrufino]

I need interact with bluetooth media buttons (miband4), but not for audio playing, but for another purpose. It is possible ? Sorry for unrelated question.

My test: The media Metadata is showing in external bluetoth (miband). But then i clink in play or pause, this not catching events.

My log shows:

2020-01-30 22:40:35.180 2021-2968/? D/MediaSessionService: Sending KeyEvent { action=ACTION_DOWN, keyCode=KEYCODE_MEDIA_PLAY, scanCode=0, metaState=0, flags=0x0, repeatCount=0, eventTime=66885018, downTime=66885018, deviceId=-1, source=0x0 } to the last known PendingIntent PendingIntent{a867d3e: PendingIntentRecord{160679f com.google.android.youtube broadcastIntent}}

After making a simple play song, now events are send to my app

mPlayer = MediaPlayer.create(this, R.raw.beep_02); mPlayer.start();

2020-01-31 01:03:31.350 3230-3230/? V/Avrcp_ext: recordKeyDispatched: KeyEvent { action=ACTION_DOWN, keyCode=KEYCODE_MEDIA_PAUSE, scanCode=0, metaState=0, flags=0x0, repeatCount=0, eventTime=74663823, downTime=74663823, deviceId=-1, source=0x0 } dispatched to io.opendevice.miband

But it is no getting this event: On main activity i tried: onKeyDown(int keyCode, KeyEvent event) and public boolean onKeyUp(int keyCode, KeyEvent event)
