Note this call

+        return pwa;
     }

It's not clear who will be calling createForActivity()

Please see my comment in window_tree_host_platform.cc. It can be done through
WTHAndroid.java. I didn't create that class - wanted to make sure the approach
is ok first, but it should be pretty straightforward.

Oh sorry, missed that. Added a comment there.
