Android - onKeyDown won't work with KEYCODE_MENU

Question

Using onKeyDown with KEYCODE_MENU do nothing but it work with KEYCODE_SEARCH

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    switch(keyCode){
        case KeyEvent.KEYCODE_MENU:
            Toast.makeText(this, "Menu key pressed", Toast.LENGTH_SHORT).show();
            return false;
        case KeyEvent.KEYCODE_SEARCH:
            Toast.makeText(this, "Search key pressed", Toast.LENGTH_SHORT).show();
            return false;
    }
    return super.onKeyDown(keyCode, event);
}

I think there is something handling the menu key so it won't listen to my code i have tried disbling onCreateOptionsMenu like this:

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    return true;
}

But still won't work..
So, any ideas to make the menu button listen to onKeyDown??

This may be a bug in appcompat v22. See https://code.google.com/p/android/issues/detail?id=159795

The workaround as posted in that thread is to override dispatchKeyEvent :

    @Override
    public boolean dispatchKeyEvent(KeyEvent event) {
        int keyCode = event.getKeyCode();
        int action = event.getAction();
        boolean isDown = action == 0;

        if (keyCode == KeyEvent.KEYCODE_MENU) {
            return isDown ? this.onKeyDown(keyCode, event) : this.onKeyUp(keyCode, event);
        }

        return super.dispatchKeyEvent(event);
    }

Edit: Please see Upgraded to AppCompat v22.1.0 and now onKeyDown and onKeyUp are not triggered when menu key is pressed

Even in use of Setup Box and Android TV you can use dispatchKeyEvent in Activity and after that detect any key you want

@Override
public boolean dispatchKeyEvent(KeyEvent event) {
    int code = event.getKeyCode();
    int action = event.getAction();
    boolean isDown = action == 0;

    if (code == KeyEvent.KEYCODE_MENU) {
        Toast.makeText(this, "Menu Is Selected", Toast.LENGTH_SHORT).show();
    }

    return super.dispatchKeyEvent(event);
}

What device and OS are you on ?

You may want to update your compat library to the latest .. 23.0.0
