I can send MMI using the approach described, for example. Call Forwarding . After sending the MMI, a response usually appears such as “Call Forwarding Activated Successfully” or something like that.
- Is it possible for activity to start trying to access this answer (especially for MMIs that request status messages, such as Call Forwarding?)?
- Is it possible that my activity would not allow the system to directly display the response to the user? I mean this in the sense of "Do not disturb the user unnecessarily," and not "furtively do things behind the back of the user"; that is, I don’t care if the user interface displays status icons, etc., I just don’t want the user to have to check a large message field each time.
- If not normal, what about the root phone?
If it depends on MMI, I am interested in MMIs who set up, request or cancel call forwarding.
