Question

How can I detect which key combination is being pressed?

For example I want to recognize Back and Menu button being pressed simultaneously or any key combination.

I would like to open my application on the basis on which key is being pressed.

I did a simple research and found this solution and it may work. You can detect Menu key pressed by the following code.

public boolean onKey(View v, int keyCode, KeyEvent event) {
        if (keyCode == KeyEvent.KEYCODE_MENU && event.getAction() == KeyEvent.ACTION_DOWN) {
            //Start a new thread here and run a while loop for listening to "back pressed" and trigger the event you want if the back button is pressed 
        } else {
            //stop the started thread above
            return false;
        }
    }

Hope this might help you. Thnks.
