AttachCurrentThread JNIEnv** instead of void**?

[amos-yau]

thanks for providing this auto binding way, to save writing JNI bridge effort (and I'm not familiar with c++).

But I hit this error when compiling:
ktbind.hpp:453:54: error: cannot initialize a parameter of type 'JNIEnv **' (aka '_JNIEnv **') with an rvalue of type 'void **'

I'm writing an Android app, NDK version 21.4.7075529, see if any more detail need to be provided?

Android appears to have a different signature for the member function AttachCurrentThread; while standard JNI has type void** as the first function parameter, Android has JNIEnv**, thus the type mismatch. Simply removing the reinterpret_cast should make the compiler succeed:

if (_vm->AttachCurrentThread(&_env, nullptr) == JNI_OK) {
