Subclassing NativeActivity makes two things possible. Firstly, we can implement an InputConnection to offer good support for IMEs, necessary for good keyboard support. Secondly, we can use it to overlay WebViews onto the NativeActivity. But to sublcass NativeActivity, we need to compile Java. To keep the toolchain go gettable, this is done with go generate. While here, check the exception after FindClass. Apparently it can throw an exception. Updates golang/go#9361. Updates golang/go#10247.
