how to surcharge(disable temporary) talkback gesture in my app?

[fred38]

i explain i'll write an application:
- for blind people,
- they have Talkback activated for their current use of the phone
- my application is a calculator
-to enter a number or an operator we use a specific character recognition (we draw a number and it is interpreted by our program)

- Can I call this a gesture operation in the sense that the mean Android?

- Can I, in my application only redefine some "gestures" (function) of Talkback, they''ll not interpreted in my application when it is in the foreground.
And re-established them, when it is no longer in the foreground

Question:
if somebody called me while I use this calculator, I think the phone function has priority over my application (?) and passes it to the foreground.

I may need to check the address book to give to my interlocutor, an address or number. (talback it will work normally in this situation)

when I closed the address book, and hangs up, my calculator returns to the forefront with "gestures" defined by them and for them


my question is: are they the gestures global (to the system) and local (to the application)
Is it possible to specify the local or global character of a gesture?

thank you

Where do you see the API to suspend it?
