Android UIAutomation Instrumentation NoSuchMethod Exception

Question

Any idea why I get this exceptions. Its supposed to be very straight forward and simple. It compiles without any errors or warnings. At run time it throws exception.

            Instrumentation im = new Instrumentation();
            UiAutomation myVar = im.getUiAutomation();
            myVar.injectInputEvent(evntDown,false);

Here's the exception.

UIAutomation was included in API 18. NoSuchMethod Exception occurs when you try to access/use a class/method that is not supported on OS/API version you are currently running the app on.
