title: How to downgrade NDK to r8e
body: <p>I migrated an android project from Eclipse to Android Studio, and updated the NDK. When I build the solution I had this error: </p>
  
  <blockquote>
    <p>Error:(61, 2) error: format not a string literal and no format arguments [-Werror=format-security]</p>
  </blockquote>

  <p>I can't find any solution, so I am thinking that I have to downgrade the NDK.
  Is there another way to resolve this? If not, how can I downgrade my NDK to r8e?</p>
