I want to log voice call and video call. I must distinguish them. Where is the difference between the intent for ACTION_NEW_OUTGOING_CALL of video call and the intent for ACTION_NEW_OUTGOING_CALL of voice call?
回答1:
There is no difference, because there are no video calls in Android at the time of this writing. Any video chat application will not be using ACTION_NEW_OUTGOING_CALL in all likelihood, so all broadcasts of ACTION_NEW_OUTGOING_CALL are for voice calls.
