As mentioned in JmeHub thread : [Do we support real mouse device in android?](url)
We need support mouse hardware in Android.

Thanks for opening the issue, in regards to mouse support, there is this API:

• View.onGenericMotionEvent

which could be adapted to produce a JME touch event here:

• AndroidInputHandler

I will see what I can do.
