KeyEvent.getCharacters() returns null instead of KEYCODE_UNKNOWN

[derenio]

While testing the RST_editor example (https://github.com/kivy/kivy/tree/master/examples/RST_Editor) on HTC Desize Z I've tried to scroll loaded rst file with my trackpad and got this exception:

the culprit line:
https://github.com/kivy/python-for-android/blob/master/src/src/org/renpy/android/SDLSurfaceView.java#L1004

The problem might be that according to http://developer.android.com/reference/android/view/KeyEvent.html#getCharacters() the trackpad's event is an ACTION_MULTIPLE and event.getCharacters() should return KEYCODE_UNKNOWN String, instead it returns null.
This might be an issue with the Android NDK itself, in that case someone more familiar with it could post this bug on a proper tracker.
