As it often happens in Android Developer "Documentation", the description of this function is ridiculously vague:
Requests feedback interruption from all accessibility services.
Does anybody know exactly what it does, what are its effects and how long it will last? For example, with TalkBack and Explore On Touch enabled, will this interrupt the current utterance that is being spoken, or will it shut down the service for the rest of the activity lifecycle?
Also, what does "request" mean? Does it mean that the request might not be satisfied? If so, in which cases, and how do you check whether it was succesful?
