how to show a AlertDialog while Pressing the HomeButton

Hi I have written the following code:

public boolean onKeyDown(int keyCode,KeyEvent event) {
    if (keyCode==KeyEvent.KEYCODE_HOME) {
        showDialog(MY_DALOG);
        return  true;
    }
    return true;
}

But when I press the HOME BUTTON, it doesn't call the line if(keyCode==KeyEvent.KEYCODE_HOME) when debugging.

On the other hand, it calls the onPause(). I have put my code in onPause() but still, it shows a SuperNotFound exception in Logcat.

Any idea how to display a dialog by pressing the HOMEKEY?

KeyEvent.KEYCODE_HOME is not for the developers. Android has made it safe for themselves. So that no application would force the user to stay inside their application.

The Home Button will be handled by the PhoneWindowManager in the Android framework. It will be sent to the Launcher application. No other application will receive it in their Activity.

This is actually possible. But you have to make your own 'home screen replacement' app, and let the user set your app as the user's new home screen. But this is probably a much more complicated solution than what you are looking for...

Sorry. you can show alert dialogue by pressing back button of device.

But, you can't implement those feature with HOME Button pressed. Because, Android is designed as automatically launch home page without consider about anything happening right now on UI, While pressing it.
