Activity_KeyPress in service intent combination?

Hello everybody,

I have the next code, it is working fine. my idea is detect when the user press too much time the hardware button (Volumen UP) and trigger the toasMessageShow("EUREKA",true).

That is working fine when the APP is running. Now the question is, how can I put the APP to work that feature KeyPress, when the APP executed the Activity.finished. It is not running so the KeyPress will not running neither of course .

will I need to put a service? mmm that will...
