[Android Keyboard Height] Page is pushed outside of screen when opening the keyboard after rotation #807

Hi,
First of all I must say that I love this plugin, you have done an amazing job and keep supporting it which makes it even more impressive, thanks man.

I have a problem with the calculation of the keyboard height on android.
If I load the page in portrait mode and then rotating to landscape opening the keyboard will push the page outside of screen.

I feel its a same issue as #729 but there its a full screen.

I tried to debug and I think its because mWindowVisibleDisplayFrameHeight is only calculate once (in init()) and not when changing orientation.

I added the calculation code from the init() in SetMargin() and the problem was solved.

Thanks
