Crash in deleteNotificationChannel in Android 11

In my app I use Foreground Service to show a notification when the app goes in background. I created a Notification Channel in the following way:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        CharSequence name = getString(R.string.app_name);
        int importance = NotificationManager.IMPORTANCE_DEFAULT;
        NotificationChannel channel = new NotificationChannel(TransactionsUtil.getNotificationChannelId(this), name, importance);
        channel.setDescription("some description");
        NotificationManager notificationManager = getSystemService(NotificationManager.class);
        notificationManager.createNotificationChannel(channel);
    }

    Notification notification = new NotificationCompat.Builder(this, TransactionsUtil.getNotificationChannelId(this))
            .setSmallIcon("some icon")
            .setContentTitle("some content")
            .setContentText("some content")
            .setContentIntent(pendingIntent)
      .setChannelId(TransactionsUtil.getNotificationChannelId(this))
            .build();
    startForeground(NOTIFICATION_ID, notification);

The I delete the notification channel in this way:

private void terminateService() {
    stopForeground(true);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        NotificationManager notificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.deleteNotificationChannel(getNotificationChannelId(this));
    }
    stopSelf();
}

Recently, I'm having some crashes in my app releated to this; in particular, I have the following error:

Fatal Exception: java.lang.SecurityException Not allowed to delete channel "channel name" with a foreground service

The problem is releated to the function terminateService, in particular in deleteNotificationChannel.

Caused by android.os.RemoteException Remote stack trace: at com.android.server.notification.NotificationManagerService$11.enforceDeletingChannelHasNoFgService(NotificationManagerService.java:3859) at com.android.server.notification.NotificationManagerService$11.deleteNotificationChannel(NotificationManagerService.java:3872) at android.app.INotificationManager$Stub.onTransact(INotificationManager.java:1813) at android.os.Binder.execTransactInternal(Binder.java:1170) at android.os.Binder.execTransact(Binder.java:1134)

It happens only in Android 11 devices. Does someone has a solution or suggestion, please?

You don't need to delete the channel, you can share the channel with your normal notification channel. You get crash because stopForeground is binder call through ActivityManagerService, it cross process, same as the deleteNotificationChannel through NotificationManagerService, if the NotificationManagerService goes fast, the method enforceDeletingChannelHasNoFgService will return true, which is added from android-11.0.0_r38, and you will get a crash.
