title: How to set NDK Build path in Windows for Android studio
body: <p>According to the  openFrameWorks instructions, I import an example project, and the first error is this: </p>
  
  <blockquote>
    <p>gradle version 2.2 is required. current version is 2.10</p>
  </blockquote>
  
  <p>After changing it to "gradle version 2.2", I get this error:</p>
  
  <blockquote>
    <p>NDK directory is invalid. Check NDK_ROOT path in paths.make</p>
  </blockquote>
  
  <p>If I change <code>NDK_ROOT</code> to <code>path_to/android-ndk-r10e</code> following Google, it doesn't help either.</p>
  
  <p>Any help would be appreciated.</p>
