method to call when home button clicked?

Question

In My android application, currently one of my activity is focused on the screen. If the user clicked on "HOME" button, which activity method gets invoked.

"Home button is reserved for the OS as a "last chance" escape for the user from any app. Developers cannot override it, this way ensuring that the user will always have the possibility to leave the app." -> http://stackoverflow.com/questions/6226001/handling-home-button-in-android — Tiago Babo, Jun 22 '11 at 12:37

You cannot override anything about the Home activity. You can only use the Home intent category.

See this other question for more info:

There is no way to handle "Home" button click. And this is by design.

Read great post by CommonsWare: Please Ignore the HOME Button. Also see this and this threads on Android Developers group.

Works for me..

@Override
public void onAttachedToWindow() {
    super.onAttachedToWindow();
    this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);
}

Then

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if(keyCode == KeyEvent.KEYCODE_HOME){
        // Your code here.
        return true;
    }
    return false;
}

Works for me on Android 2.3. However it seems to be a hack rather then intended use of API and does not work for me on Android 4. – Miriam Apr 10 '13 at 16:36
