title: Android Studio 2.2 in Ubuntu 14.04 LTS gives Error : "Gradle sync failed: Cause: error=13, Permission denied"
body: <p>I have installed android 2.2 in ubuntu 14.04 LTS but when I try to run an android app it shows immediate error:
  <strong>"Gradle sync failed: Cause: error=13, Permission denied. Consult IDE log for more details (Help | Show Log)".</strong></p>
  
  <p>When I looked into the terminal while I tried to run the android app, it gives below message in terminal:
  <strong>WARN - roid.tools.ndk.GradleWorkspace - NDK support for project 'MyApp' is disabled because the project doesn't contain any valid native configurations.</strong> </p>
  
  <p>I have tried every possible solution on google/stackoverflow but nothing was helpful. Any help/suggestion would be appreciated. Thanks.</p>
