Undefined reference to AAssetManager_fromJava

My mistake. I didn't have "android" library added to the linker. I have actually setup NDK dev environment on Visual Studio Express and "android" library wasn't added to my project by default.

If you are using makefiles, be sure to add -landroid to your LOCAL_LDLIBS when using native AssetManager.

Android Studio developers, İf you have ExternalNativeBuild file which is called "CMakeList.txt" you must append this code to the file CMakeList.txt

find_library( # Sets the name of the path variable.
          android-lib

          # Specifies the name of the NDK library that
          # you want CMake to locate.
          android )
target_link_libraries( 
                   ${log-lib}
                    ${android-lib})

if you also have native lib you can add easily like this

target_link_libraries( native-lib
                   ${log-lib}
                    ${android-lib})

It should work!
