AS 指定特定版本NDK

在使用最新的AS编译ndk代码时，抛出以下错误：

CMake Error at C:/Users/Administrator/AppData/Local/Android/Sdk/ndk-bundle/build/cmake/android.toolchain.cmake:250 (message):
stlport_static is no longer supported.  Please switch to either c++_shared
or c++_static.  See
https://developer.android.com/ndk/guides/cpp-support.html for more
information.

C:/Users/Administrator/AppData/Local/Android/Sdk/cmake/3.6.4111459/share/cmake-3.6/Modules/CMakeDetermineSystem.cmake:98 (include)
CMakeLists.txt

问题原因 ，Ad使用了ndk 20版本，将其改为原来的14版本

//local.properties文件中添加
ndk.dir=C\:\\Users\\Administrator\\AppData\\Local\\Android\\Sdk\\ndk\\android-ndk-r14b
