// For
//     com/google/vr/internal/controller/NativeCallbacks

// Local modification includes:
// 1. Remove all implementaiton, only keep definition.
// 2. Use absolute path instead of relative path.
// 3. Removed all helper functions such as: Create.
// 4. Removed external functions that don't have implementation in shim file.
// 5. Replace all nativeHandle to handle. This is because jni_generator.py
// require jni functions start with "native" prefix. So we add the prefix to
// generate the file. But the real jni functions in the static library
// doesn't have the prefix.
// 6. Added function RegisterNativeCallbacksNatives at the end of this file.
