I have requiremt something like this. Suppose my application is installed in device (though it is not in running mode. may be it is pause state.) Now if user gives long press on back button application's activity should get awake and start working what ever I whave written in it.
How to make this possible. Any idea from where should I start. I know this is possible.
And if you are not clear with my question you can ask me for further details.
