NotificationCanceler

এই অ্যাপটি সব বিজ্ঞপ্তি বাতিল করে।

This app cancels all Notifications that don't have FLAG_NO_CLEAR and FLAG_ONGOING_EVENT by using NotificationListenerService#cancelNotification() while this app is permitted to access Notifications by Settings.

This is basically for development purpose or demo purpose (It is desirable not to show Notifications during the demo).
