Cannot forward declare "public static" methods, since this is "extern", which
conflicts with "static" declarations produced by JNI Generator.  Filed this
issue as  http://crbug.com/382985 .

Why does it have to be public? It will only be used inside of this class to call
ime_adapter_android.cc so you can make it private.
