Answer 1

You need to set a custom intent action, not the AudioPlayerBroadcastReceiver component class.

Create a Intent with custom action name like this

Intent switchIntent = new Intent("com.example.app.ACTION_PLAY");

Then, register the PendingIntent Broadcast receiver

PendingIntent pendingSwitchIntent = PendingIntent.getBroadcast(this, 100, switchIntent, 0);

Then, set a onClick for the play control, do similar custom action for other controls if required.

notificationView.setOnClickPendingIntent(R.id.btn_play_pause_in_notification, pendingSwitchIntent);

Next, register the custom action in AudioPlayerBroadcastReceiver like this

Finally, when play is clicked on Notification RemoteViews layout, you will receive the play action by the BroadcastReceiver

public class AudioPlayerBroadcastReceiver extends BroadcastReceiver{
    @Override
    public void onReceive(Context context, Intent intent) {

        String action = intent.getAction();

        if(action.equalsIgnoreCase("com.example.app.ACTION_PLAY")) {
            // do your stuff to play action;
        }
    }
}

EDIT: how to set the intent filter for Broadcast receiver registered in code

You can also set the Custom Action through Intent filter from code for the registered Broadcast receiver like this

    // instance of custom broadcast receiver
CustomReceiver broadcastReceiver = new CustomReceiver();

IntentFilter intentFilter = new IntentFilter();
intentFilter.addCategory(Intent.CATEGORY_DEFAULT);
// set the custom action
intentFilter.addAction("com.example.app.ACTION_PLAY");
// register the receiver
registerReceiver(broadcastReceiver, intentFilter);
