title: Android NDK C++ 'wstring' support
body: <p>I have source code/lib written in C++ - now i would like to compile and use the same in Android NDK project (NDK 6). I am able to compile most of the C++ files except "std::wstring" based functionality. </p>
  
  <p>In Application.mk when i specify <code>APP_STL: = stlport_static</code> then it compiles <code>std::wstring</code> based code but when i specify <code>APP_STL: = gnustl_static</code> it fails to compile. I do not know how to resolve <code>std::wstring</code> related issue with <code>APP_STL: = gnustl_static</code></p>
  
  <p>Any pointer or help on this would be greatly appreciated.</p>
