Android Question Start activity on the lock screen
You must have seen many times that in WhatsApp, someone calls us and our phone screen turns on and the call activity is started! I want to implement exactly this feature in my program. (The user's phone may or may not be locked ...) please guide me. Thankful❤️- HassanProgrammer
