BlackBerry Unable to close camera using EventInjector for touch screen

So I believe I have found a way to make this work consistently. My
Issue was not the permissions, as all along I was testing with
Proper permissions set (or by prompting hte user to set them).
Solution I found is to put a Thread. sleep (500) between the two injected
ESCAPE events as follows:

 

 

EventInjector.KeyEvent inject = new EventInjector.KeyEvent(EventInjector.KeyEvent.KEY_DOWN, Characters.ESCAPE, 0);
                inject.post();
                sleep(500);
                inject.post();

I'm
Not exactly sure why this works, and I'm not saying that it's the right
Way to solve the problem, but it works for me. I tried shorter sleep
Times but 500 ms was the shortest that I cocould get to consistently work.
Also, this didn't work when I used the EventInjector. invokeEvent ()
Method, only with the post () method. Hope this helps some people out.
