App won't close (Glass, Unity3d)

Question

I have an Android Studio project, generated from a Unity3d Project.

I wanted to run my project on a Google Glass so I followed this tutorial (http://forum.unity3d.com/threads/how-to-build-for-google-glass.219558/).

Everything works fine so far, but I can't close the app via swipe down, even though I added this to the UnityPlayerActivity.java:

@Override public boolean onKeyDown(int keyCode, KeyEvent event)   {
    if(keyCode == KeyEvent.KEYCODE_BACK){ finish(); }
    return true;
}

Again, everything else works just fine.

1st UPDATE:

I tried the application on a tablet - like on the Glass, "Back"-button does not work.

Then I implemented this in Unity:

if(Input.GetKeyDown(KeyCode.Escape)){
    Application.Quit();
}

Now it works on the tablet, but the Glass-situation did not change.

2nd UPDATE:

This also didn't work: this.finishAffinity();

3rd UPDATE:

I tried to close my Unity Application using this Coroutine in the Start()-Method:

IEnumerator waitAndExit(int sec)
{
    yield return new WaitForSeconds(sec);
    Application.Quit();
}

This successfully shuts down my application, so the problem appears to be this:

Unity does not recognize swiping down on Google Glass as a keyEvent in Input and the UnityPlayer object seems to get ALL input from android.

How can I stop that?
I wan't to handle touchpad events with java, but my original idea - overriding onKeyDown - did not work.

4th Update:

I tried to recognize a gesture like in this answer and added this to my onCreate():

mUnityPlayer.setFocusable(false);
//mUnityPlayer.requestFocus();

Unfortunately it did not help.

Did you debug to see whether the method is called with the parameters you expect? If `finish()` is called, what does it do? — Thomas, Oct 05 '15 at 15:07
log your code and check what happen there or if it really gets there. Are you sure that swipe gesture calls "KEYCODE_BACK"? — Mariano Zorrilla, Oct 05 '15 at 15:08
@Thomas I am 100% sure `finish()` works, as I tested it seperately and `Toast.makeText(...).show()` also won't work. — 000000000000000000000, Oct 08 '15 at 09:41
@MarianoZorrilla According to the GDK docs, yes! And I also tried to detect a gesture (s. my 4th Update of the question). It did not work. — 000000000000000000000, Oct 08 '15 at 09:43

This is not really a solution, but rather a work-around:

Using contextual voice commands works fine, even with the UnityPlayer-object blocking touchpad input.

I now close my app via "OK glass - quit".

If anybody figures out how to solve it properly - I'll test, verify and accept your answer.
