I think you also mentioned that you want to make over-panning always enabled in
multi-window mode. Is this something you want to do later?

IIUC change of soft keyboard's visibility will always trigger a
SystemUiVisibilityChanged event, right?

Definitely later, we cannot compile against the N SDK yet.

Yes it will.

             mSystemUiScreenSize.set(parameter.left, parameter.top,
                     mRenderData.screenWidth - parameter.right,
                     mRenderData.screenHeight - parameter.bottom);
