I haven't ever wrote an Android app (just toyed around and patched a few projects, but never had an idea and a necessity to do a full one from scratch), but what's the limitation here?

Can't a native library call just anything from the Android/Java world?

I mean, NDK library has JNIEnv* pointer and it can call FindClass/GetMethodID/Call*Method. And it can create objects/functions if it needs to be called back. Of course this isn't fun in the raw form, but don't see any reason it can't be well sugared.

You don't gain anything except a huge debugging pain and a large loss of performance. Debugging JNI and performance loss of translation makes not using JVM downright madness.
