../include/mem.h not found while building using Android Studio

[Syamala Dasi]

I am building a native app using Android Studio. I installed ndk-bundle and I cannot find mem.h in there. 

Here is the error i get while building the project: 

C:\Users\pvenkatayogi\AppData\Local\Android\sdk\ndk-bundle\sources\cxx-stl\stlport\stlport\mem.h Error:(40, 14) '../include/mem.h' file not found

C:\Users\pvenkatayogi\AppData\Local\Android\sdk\ndk-bundle\sources\cxx-stl\stlport\stlport\stl\config_android.h Information:(59, 39) expanded from macro '_STLP_NATIVE_C_HEADER'

NDK version in your ${NDK_ROOT_DIR}\source_properties?  in the format of:
  Pkg.Desc = Android NDK
  Pkg.Revision = 14.0.3843981
