Android Toast doesn’t show up

I am using a Samsung Galaxy Note 8 with Android 8.0.

My Toast message (which was working) does not show up

Toast.makeText(this, "ABC", Toast.LENGTH_SHORT).show();

getApplicationContext(), getBaseContext() are not helping instead of this. Using this in an activity.

Answer

Go to your app settings -> Notifications and check if notifications are turned on. This action is possible in newer android versions

Even though a Toast is not a notification, it seems that NotificationManagerService.java will not show Toast if Notifications are disabled.
