Question

I have an activity that starts a service like that:

    Intent youtubeIntent = new Intent(this, YoutubeFeedService.class);
    service = startService(youtubeIntent);

and to detect when the service stops I use a broadcast receiver:

@Override
public void onResume() {
    IntentFilter filter; 
    filter = new IntentFilter(YoutubeFeedService.NEW_VIDEO_CELL); 
    receiver = new FeaturedReceiver(); 
    registerReceiver(receiver, filter);
    super.onResume();
}

@Override public void onPause() {
    unregisterReceiver(receiver); 
    super.onPause();
}



public class FeaturedReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        String title = intent.getStringExtra("title");


        if (title.equals("-1") || title.equals("1")){
            //stopService(new Intent(FeaturedActivity.this, service.getClass()));
            try {
                Class serviceClass = Class.forName(service.getClassName());
                stopService(new Intent(FeaturedActivity.this, serviceClass));
            } 
            catch (ClassNotFoundException e) {}

        }

    }
}

I first tried to kill the service with

stopService(new Intent(FeaturedActivity.this, service.getClass()));

but this didn’t work, so instead I used

try {
                Class serviceClass = Class.forName(service.getClassName());
                stopService(new Intent(FeaturedActivity.this, serviceClass));
            } 
            catch (ClassNotFoundException e) {}

And it did work! Can anyone explain what’s the difference?

Thanks

Answer 1

stopService(new Intent(FeaturedActivity.this, service.getClass()));

In this case, service is a ComponentName. Hence, service.getClass() will return ComponentName.class. Your service is YoutubeFeedService.class.

Class serviceClass = Class.forName(service.getClassName());
stopService(new Intent(FeaturedActivity.this, serviceClass));

It would seem simpler to call:

stopService(new Intent(FeaturedActivity.this, YoutubeFeedService.class);
