i am trying to catch the physical button events on a motorola ht820
bluetooth headset and it i cannot seem to trap those events.
the media player on the device *is* able to catch those events.
based, on what I've read and googled for, it seems like this should do
the trick --
rec = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
KeyEvent event = (KeyEvent) intent.getParcelableExtra
(Intent.EXTRA_KEY_EVENT);
if (event != null && event.getAction() ==
KeyEvent.ACTION_DOWN) {
switch (event.getKeyCode()) {
case KeyEvent.KEYCODE_HEADSETHOOK:
case KeyEvent.KEYCODE_MEDIA_PLAY_PAUSE:
getInstance().playpause();
abortBroadcast();
break;
case KeyEvent.KEYCODE_MEDIA_STOP:
getInstance().stop(true);
abortBroadcast();
break;
case KeyEvent.KEYCODE_MEDIA_NEXT:
getInstance().next();
abortBroadcast();
break;
case KeyEvent.KEYCODE_VOLUME_UP:
AudioManager audioMgrUp = (AudioManager)
getSystemService(Context.AUDIO_SERVICE);
audioMgrUp.adjustStreamVolume(
AudioManager.STREAM_MUSIC,
AudioManager.ADJUST_RAISE,
AudioManager.FLAG_SHOW_UI);
break;
case KeyEvent.KEYCODE_VOLUME_DOWN:
AudioManager audioMgrDown = (AudioManager)
getSystemService(Context.AUDIO_SERVICE);
audioMgrDown.adjustStreamVolume(
AudioManager.STREAM_MUSIC,
AudioManager.ADJUST_LOWER,
AudioManager.FLAG_SHOW_UI);
break;
}
}
}
};
// Use a separate receiver for ACTION_MEDIA_BUTTON broadcasts,
// since we need to manually adjust its priority (to make sure
// we get these intents *before* the media player.)
IntentFilter intentFilter = new IntentFilter(
Intent.ACTION_MEDIA_BUTTON);
but it does not seem to work.
Here's what I'm seeing in the logcat.
any ideas? tia.
