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

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

Edit:

I don't want to call onDestroy() explicitly. I want to remove notification when I remove my app from the device menu of running applications. Because when I stop my application, onDestroy() don't call and my notification remains in the status bar.

I have started my service with this code.

Intent playin = new Intent(this, MusicService.class);
startService(playin);

Do you mean that you want to log when the application crashes? — Wolfish, Jul 18 '14 at 12:53
Do you want to call the onDestroy() of the service or do you want to know when the service crashes so you can get rid of you notification. — DrkStr, Jul 18 '14 at 13:11
How are you starting your service? is it bounded server or unbounded? — Ashwin N Bhanushali, Jul 18 '14 at 13:13

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.

Will `stopSelf()` invoke `onDestroy()`? – IgorGanapolsky Jul 08 '16 at 14:05

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).

Reference:

1) Service onDestroy().

2) how-to-check-if-a-service-is-running-in-android.

So should `stopSelf()` be called instead of `onDestroy()`? – IgorGanapolsky Jul 08 '16 at 14:06 — IgorGanapolsky, Jul 08 '16 at 14:06

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.

You should use Foreground service. In your case, I think it would be the best choice.

Foreground services show a status bar notification, so that users are actively aware that your app is performing a task in the foreground and is consuming system resources. The notification cannot be dismissed unless the service is either stopped or removed from the foreground.

To work with foreground service you first need to declare permission <uses-permission android:name="android.permission.FOREGROUND_SERVICE"/> in your manifest. It is a normal permission so doesn't requires user action.

then, you can start the service for you Activity or other component using applicationContext.startForgroundService(intent). this is to tell the system that this will be a foreground service.

You need to start the foreground service from within your service(usually in onStartCommand()) using startForeground(int, Notification) and stop the service foreground service using stopForeground(boolean)(it takes a boolean asking whether you want to remove the notification or not)

after starting foreground service, if you close your app or the service stops itself, the notification will be remove too.

Note: when you manually want to stop the service, you should call stopSelf() or stopService() as calling stopForeground() is not enough, it merely remove the notification from the status bar.

Call onDestroy() of Service
