title: TouchScreenKeyboard.area on Android with Unity3D
body: <p>Anyone using Unity3D has tried to solve the problem that TouchScreenKeyboard.area isn't supported on Android devices? This is because for Android you can't get the size of the soft keyboard. By looking into the issues deeper, I figure out that you have to write your own java code for this. Then the problem is there is no native interfaces for this.</p>
  
  <p>My question is: what's the best way to get the area(size) of the TouchScreenKeyboard on Android devices?</p>
