how can find out how many BroadcastReceiver registered on the phone

Question

I'm on sms application that should find out how many sms receivers registers in user phone. I googled and find this link but it seems that you can just get your package receivers with:

  List<ResolveInfo> myList = getPackageManager().queryBroadcastReceivers(i,0);

Answer 1

The Intent you pass in the queryBroadcastReceivers() call needs to match up with the <intent-filter> of the Receivers you're looking for. In your case, you simply need to create the Intent with the SMS_RECEIVED action.

Intent i = new Intent("android.provider.Telephony.SMS_RECEIVED");
