How to use c++11 feature in ANE in Android

I have a c++ project uses unordered_map, when packaging the windows ANE works fine but when packaging the android ANE it gives the #3500 error "The extension context does not have a method with the name".

Creating the android ANE first compile c++ source code with Android NDK r10e with enabling c++11,and stl features to generate the so file.

Removing unordered_map from code leads ANE to work.

What is the problem here.

Sorry for my english.
