SOLVED::How to run/build cpp tests on android studio

Can any one explain me how to run/build cpp tests on Android Studio for windows 8.1 OS.
I am trying to build it but not getting to execute it and getting error

Using Eclipse project : E:\sid\soft\cocos2d-x-3.7\tests\cpp-tests\proj.android
Android platform not specified, searching a default one…
Can’t find right Android-platform for project : ‘E:\sid\soft\cocos2d-x-3.7\tests
\cpp-tests\proj.android’. The Android-platform should be equal/larger than 20.
Build dynamic library for project [ E:\sid\soft\cocos2d-x-3.7\build…\tests/cpp
-tests ] fails!

I am working with following configuration:
OS-Win 8.1
VS2013 update4
android-studio-bundle-141.2456560
sdk platform 23 and 22

I need it urgent.
Thanx in advance.
