Custom ContactsDirectoryProvider is not called for some operations

Question

I\'ve implemented custom ContactsDirectoryProvider which works fine when Contacts or Dialer applications are searching for contacts using URIs of the form content://

Answer 1

A workaround that we are using is to use a BroadcastReceiver to listen to incoming calls:

Then in the onReceive method of the BroadcastReceiver you can get the incoming number:

intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER)

(This requires the READ_CALL_LOG permission starting with Android Pie)

Then you can use the incoming number to match a person and show a toast and or notification
