[Request] Please, move AndroidJNI.h into a public section

I’m trying integrate some java sdk into UE4. I succeed with library integration, but for now, because GetJavaEnv is hidden, can’t access to this lib without rewriting engine sources and engine recompilation. If you don’t plan to make android plugins for a while, at least move JNI-dependent stuff into public, Also, extending JNI_OnLoad with some kind of “OnLoad” event may be useful.

P.S. Solved for now with “extern” local defenitions.
