You have to this in the Android OS, PhoneWindowManager, this is where the HOME button is handled.

Specificly: http://androidxref.com/4.1.1/xref/frameworks/base/policy/src/com/android/internal/policy/impl/PhoneWindowManager.java#1761

To change that you have to change and build the AOSP. And flash this on you device. Therefore for app developers this is not possible.

If homekey is pressed in the activity it will come to

@Override
    protected void onUserLeaveHint() {
        // TODO Auto-generated method stub
        super.onUserLeaveHint();
    }

put the counter and when it reached to 3 perform the action.

i want to capture home key from home screen of android phone – Ajay S Nov 29 '12 at 10:39
so where is your application is running? is it a widget? or service? – Dinesh Prajapati Nov 29 '12 at 10:41
then it's not possible because it's in the background UI less thing which is not affected with home key press. – Dinesh Prajapati Nov 29 '12 at 10:46
is there any way rather than service – Ajay S Nov 29 '12 at 10:50
Depends on what are you doing with service? – Dinesh Prajapati Nov 29 '12 at 10:51
