Instead of

stopForeground(true)

calling,

stopForeground(false)

should retain the notification as it is (without ongoing state) unless it is dismissed by user/removed programmatically.
This also should prevents notification flashing since I am not recreating the notification.

But it does not work. stopForeground(false) has the same behavior of stopForeground(true).

This is a sample project:

public class AudioTestService extends Service {

private static final String CHANNEL_ID = "TestChannel";

private static final int NOTIFICATION_ID = 14;

Notification mBuilder;



public AudioTestService() {

}



@Override

public IBinder onBind(Intent intent) {

    // TODO: Return the communication channel to the service.

    // throw new UnsupportedOperationException("Not yet implemented");

    return null;

}



@Override

public void onTaskRemoved(Intent rootIntent) {

    stopForeground(true);

    super.onTaskRemoved(rootIntent);

}



@Override

public int onStartCommand(Intent intent, int flags, int startId) {



    Intent intentA = new Intent(this, MainActivity.class);

    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);

    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intentA, 0);



    Notification mBuilder = new NotificationCompat.Builder(this, CHANNEL_ID)

            .setSmallIcon(R.mipmap.ic_launcher)

            .setContentTitle("Titolo")

            .setContentText("Descrizione")

            .setContentIntent(pendingIntent)

            .setOngoing(false)

            .setPriority(NotificationCompat.PRIORITY_DEFAULT)

            .build();

    this.mBuilder = mBuilder;

    createNotificationChannel();

    startForeground(NOTIFICATION_ID, mBuilder);



    return START_STICKY;

}



private void createNotificationChannel() {

    // Create the NotificationChannel, but only on API 26+ because

    // the NotificationChannel class is new and not in the support library

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {

        CharSequence name = CHANNEL_ID;

        String description = CHANNEL_ID + "Description ";

        int importance = NotificationManager.IMPORTANCE_DEFAULT;

        NotificationChannel channel = new NotificationChannel(CHANNEL_ID, name, importance);

        channel.setDescription(description);

        // Register the channel with the system; you can't change the importance

        // or other notification behaviors after this

        NotificationManager notificationManager = getSystemService(NotificationManager.class);

        notificationManager.createNotificationChannel(channel);

    }

}



@Override

public void onDestroy() {

    stopForeground(false);

    //NotificationManagerCompat.from(this).notify(NOTIFICATION_ID, mBuilder);

    super.onDestroy();

} }

The activity, easily handle the button click event:

public class MainActivity extends AppCompatActivity implements View.OnClickListener {

@Override

protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);



    Button startService = findViewById(R.id.startService);

    Button stopService = findViewById(R.id.stopService);

    Button stopNotification = findViewById(R.id.stopWithNotification);



    startService.setOnClickListener(this);

    stopService.setOnClickListener(this);

    stopNotification.setOnClickListener(this);

}



@Override

public void onClick(View v) {

    switch (v.getId()) {

        case R.id.startService:

            ContextCompat.startForegroundService(this, new Intent(this, AudioTestService.class));

            break;

        case R.id.stopService:

            finish();

            break;

        case R.id.stopWithNotification:

            stopService(new Intent(this, AudioTestService.class));

            break;

    }

}}

If you look at the Service's onDestroy() method I set

stopForeground(false);

instead of the method onTaskRemoved() that should remove the notification when the app is cleaned from the task list.

What am I doing wrong?

Please do not mark this as duplicated, I am looking for a solution for days...

Instead of calling stopForeground(false); from onDestroy(), send a broadcast from activity (with action) for stop service. Change your onStartCommand code to check action in intent and do startForeground or stopForeground(false);
