Question

After reading the android dev-guide and some posts here, I have implemented a simple solution to capture a HEADSET UNPLUG event in my tablet running Android 2.3.3.

Unfortunately it seems I’m missing something since the onReceive() event never gets captured.

Bellow is the implemented code:

public class MusicIntentReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {

        if (intent.getAction().equals(android.media.AudioManager.ACTION_AUDIO_BECOMING_NOISY)) {
            Toast.makeText(context, "Headphones disconnected.", Toast.LENGTH_SHORT).show();
        }

    }


}

And in the android manifest file:

<receiver android:name=".MusicIntentReceiver">
            <intent-filter>
                <action android:name="android.media.AUDIO_BECOMING_NOISY" />
            </intent-filter>
        </receiver>

What am I missing?

Answer 1

The NOISY filter gets triggered when audio output sources change, and might cause funky stuff.

The correct filter for headset plug should be:

IntentFilter commandFilter = new IntentFilter();
commandFilter.addAction(Intent.ACTION_HEADSET_PLUG);

The Manifest should read:

 <intent-filter>
            <action android:name="android.intent.action.HEADSET_PLUG" />
 </intent-filter>
