Android Studio – broadcast receiver for ACTION_HEADSET_PLUG not getting called

i’m having a broadcast reciever:

private final BroadcastReceiver mediaReceiver = new MediaChangeReceiver(this);

and i’m adding filters to it

IntentFilter filter = new IntentFilter();
filter.addAction(AudioManager.ACTION_SCO_AUDIO_STATE_UPDATED);
filter.addAction(BluetoothHeadset.ACTION_CONNECTION_STATE_CHANGED);
filter.addAction(Intent.ACTION_HEADSET_PLUG);
context.registerReceiver(mediaReceiver, filter);

and I have listener to listen for that calls

@Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        switch (action) {
            case Intent.ACTION_HEADSET_PLUG:
                //do something
                Log.e ("test", "headset plug has been called");
                break;

            case BluetoothHeadset.ACTION_CONNECTION_STATE_CHANGED:
                //do something
                Log.e ("test", "ACTION_CONNECTION_STATE_CHANGED has been called");
                break;

            case AudioManager.ACTION_SCO_AUDIO_STATE_UPDATED:
                //do something
                Log.e ("test", "ACTION_SCO_AUDIO_STATE_UPDATED has been called");
                break;

            default:
                //do something
                Log.e ("test", "default been called");
                break;
        }
    }

but when I’m connecting BT headphones (after the broadcast receiver has been called)
I don’t get any of the broadcast receiver intents called

here is the full broadcast receiver class

public class MediaChangeReceiver extends BroadcastReceiver {

    private static final String LOG_TAG = MediaChangeReceiver.class.getName();
    private MediaChangeListener mListener;

    public MediaChangeReceiver(MediaChangeListener listener) {
    super();
    mListener = listener;
    }

    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        switch (action) {
            case Intent.ACTION_HEADSET_PLUG:
                //do something
                Log.e ("test", "headset plug has been called");
                break;

            case BluetoothHeadset.ACTION_CONNECTION_STATE_CHANGED:
                //do something
                Log.e ("test", "ACTION_CONNECTION_STATE_CHANGED has been called");
                break;

            case AudioManager.ACTION_SCO_AUDIO_STATE_UPDATED:
                //do something
                Log.e ("test", "ACTION_SCO_AUDIO_STATE_UPDATED has been called");
                break;

            default:
                //do something
                Log.e ("test", "default been called");
                break;
        }
    }
}

here is my intent in the manifest

<receiver android:name=".MediaChangeReceiver"
            android:exported="false">
            <intent-filter>
                <action android:name="BluetoothHeadset.ACTION_CONNECTION_STATE_CHANGED" />
                <action android:name="Intent.ACTION_HEADSET_PLUG" />
            </intent-filter>
</receiver>

what am I doing wrong? can anyone help?
