已在Android中注册BroadCast接收器

Question

Is there a way to "Scan" All Apps for registered BroadCastReceiver for a specific Action & get the class Name, for example Action Screen On/Off(if root is needed no problems) ?

Thanks

Answer 1

Create the desired Intent . Use PackageManager and queryBroadcastReceivers() to find out who all responds to that Intent , at least for manifest-registered receivers. I do not know if PackageManager returns receivers registered via registerReceiver() , and since that's the only type of receiver that works with ACTION_SCREEN_OFF and ACTION_SCREEN_ON , you might not be able to get data for those specific actions.
