irrlicht/source/Irrlicht/Android/CKeyEventWrapper.cpp
cutealien cc428473cc - Handle Android keyboard input in the engine.
- Extend example to show/hide a soft keyboard
- Extend example to use fake mouse-events for gui (as it's probably going to take a long time until I get to working on a better solution)
Input-handling needs some JNI calls. I've put that in a new jni namespace (check CKeyEventWrapper files). 
The general idea is that every time we add a jni wrapper to Irrlicht we create a wrapper class which wraps just those functions which are needed internally.
