Call onDestroy() of Service

Question

I want to call

onDestroy()

method of Service in android.

I already searched a lot on internet and many answers are like if

service force stop or somehow its onDestroy() will never call.

But I really need to know when service is stop.

My project is about music player.

So it uses service and there is ongoing notification. I need to find out when service stop? and need to stop music and remove notification.

But it never show any log of onDestroy(). Can anyone help me what is the alternative for it? if not onDestroy() then which method and how?

Edit:

I dont want to call ondestroy explicitly. I want to remove notification when i remove my app from device menu of running application. Because when i stop my application, ondestroy dont call and my notification remains in status bar.

I have started my service with this code. Intent playin = new Intent(this, MusicService.class); startService(playin);

Answer 1

From within the Service class, call:

stopSelf();

From within another class, like your MainActivity for example:

Intent i = new Intent(this, ServiceName.class); stopService(i);

Both of these will stop your service. Make sure you are returning START_NOT_STICKY so that the service doesn't start back up again.

Answer 2

When you want to stop your service then simply fire an intent to stop the service as shown below.

Intent intent = new Intent();
intent.setClass(getApplicationContext(), YourService.class);
stopService(intent);

This is to stop service forcefully.When you stop service in this manner it's guaranteed that onDestroy method is called by android framework.

Hope this helps to solve you issue.

Answer 3

I want to call onDestroy() method of Service in android.

• Do not call this method directly

public void onDestroy ()

Called by the system to notify a Service that it is no longer used and is being removed. The service should clean up any resources it holds (threads, registered receivers, etc) at this point. Upon return, there will be no more calls in to this Service object and it is effectively dead. Do not call this method directly.

However you can check if the service is running or not.

I need to find out when service stop? and need to stop music and remove notification.

Use the following way -

private boolean isMyServiceRunning(Class<?> serviceClass) {
    ActivityManager manager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
    for (RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
        if (serviceClass.getName().equals(service.service.getClassName())) {
            return true;
        }
    }
    return false;
}

Then call it using - isMyServiceRunning(MyService.class).
