android - How to detect app removed from the recent list?

Question

I'm working on a music app, and I want stop the service when user removes the application from the recent list and not when the first activity is destroyed(because when user clicks back back until app minimizes, in that case first activity is also getting destroyed). Please help.

I want stop the service when user removes the application from the recent list.

Yes, you can either do that using stopWithTask flag as true for Service in Manifest file.

Example:

<service
    android:enabled="true"
    android:name=".MyService"
    android:exported="false"
    android:stopWithTask="true" />

OR

If you need event of application being removed from recent list, and do something before stopping service, you can use this:

<service
    android:enabled="true"
    android:name=".MyService"
    android:exported="false"
    android:stopWithTask="false" />

So your service's method onTaskRemoved will be called. (Remember, it won't be called if you set stopWithTask to true).

public class MyService extends Service {

    @Override
    public void onStartService() {
        //your code
    }

    @Override
    public void onTaskRemoved(Intent rootIntent) {
        System.out.println("onTaskRemoved called");
        super.onTaskRemoved(rootIntent);
        //do something you want
        //stop service
        this.stopSelf();
    }
}

Hope this helps.
