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 

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);
