How can I enable or disable the home button on Android?

Question

How can I enable or disable the home button on Android tablets?

Its like an `emergency` button for the user. Why would you want to take that away from them? — Shobhit Puri, Jul 13 '13 at 07:03

There is no way to detect the HOME button pressed. One way you can handle it is that if your transaction is on UI thread, then you can check in `onPause()` method if the person is trying to pause the activity or sth. Other way which I can think of it to start a background process and do that transaction thing from there. — Shobhit Puri, Jul 13 '13 at 07:25
http://stackoverflow.com/questions/17183905/how-to-disable-home-button-in-android/17183967#17183967. you cannot disable home button. If you want to handle the HOME button, implement a home screen. — Raghunandan, Jul 13 '13 at 07:41

By implementing Overided methods onAttachedToWindow() and onKeyDown() it's work fine.

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


    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {

        if (keyCode == KeyEvent.KEYCODE_HOME) {
            Log.d("Home Button", "Clicked");
        }
        if (keyCode == KeyEvent.KEYCODE_BACK) {

            finish();
        } 
        return false;
    };

Without overriding onAttachedToWindow method KEYCODE_HOME doesn't work.

Note:Home key press is handled by the framework and is never delivered to applications.

This is a flaw in version <4.0 and is not working from ICS.

Try this code.

@Override
public void onAttachedToWindow() {
    Log.i("TESTE", "onAttachedToWindow");
    this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);
    super.onAttachedToWindow();
}
