            .setContentIntent(pendingIntent)
            .setSound(defaultSoundUri).setAutoCancel(false)
            .setLargeIcon(BitmapFactory.decodeResource(GlobalController.context.getResources(), R.drawable.modem))
            .setColor(Color.argb(255, 255, 152, 0))
            .setPriority(Notification.PRIORITY_MAX);

          CustomNotification customNotification = new CustomNotification();
          customNotification.notifiaction(message);
          startForeground(1, customNotification);

    return Service.START_STICKY;
  }

  public void onTaskRemoved(Intent rootIntent) {
    Intent restartService = new Intent(getApplicationContext(),
      this.getClass());
    restartService.setPackage(getPackageName());
    PendingIntent restartServicePI = PendingIntent.getService(getApplicationContext(), 1, restartService, PendingIntent.FLAG_ONE_SHOT);
    AlarmManager alarmService = (AlarmManager) getApplicationContext().getSystemService(Context.ALARM_SERVICE);
    alarmService.set(AlarmManager.ELAPSED_REALTIME, SystemClock.elapsedRealtime() + 5000, restartServicePI);

Answer 1

On Android 10, you MUST call setSmallIcon on your notification, otherwise the notification will be ignored. (The same is not true on Android 11, where it works regardless of whether you set the small icon.) If you fail to set the small icon, instead of your notification you will see a canned Android notification instead of your own:

This code with setSmallIcon works:

                new Notification.Builder(getApplicationContext(), channelId)
                        .setSmallIcon(Icon.createWithResource(this, R.drawable.myicon))
                        .setLargeIcon(Icon.createWithResource(this, R.drawable.myicon))
                        .setContentTitle(title)
                        .setContentText(text)
                        .setCategory(Notification.CATEGORY_CALL)
                        .setExtras(extras)
                        .setAutoCancel(true)
                        .addAction(android.R.drawable.ic_menu_call, "Accept", piAcceptIntent)
                        .setFullScreenIntent(pendingIntent, true);

This code without setSmallIcon causes the problem:

                new Notification.Builder(getApplicationContext(), channelId)
                        .setLargeIcon(Icon.createWithResource(this, R.drawable.myicon))
                        .setContentTitle(title)
                        .setContentText(text)
                        .setCategory(Notification.CATEGORY_CALL)
                        .setExtras(extras)
                        .setAutoCancel(true)
                        .addAction(android.R.drawable.ic_menu_call, "Accept", piAcceptIntent)
                        .setFullScreenIntent(pendingIntent, true);

In the comments above, @royas and @Flamychandayo found this solution. I am adding this as an answer to help make the solution more clear to those who come across this question.
