title: Error running MyActivity: Gradle project sync failed. Please fix your project and try again
body: <p>I am new to Android Studio and I have just created a new project with only one Activity with fragments(Android studio created that), and when I ran the MyActivity.java , error occurs:</p>
  
  <pre><code>Error running MyActivity: Gradle project sync failed. Please fix your project and try again.
  </code></pre>
  
  <p>Nothing more in my event log.</p>
  
  <p>I have no idea why it is, and <a href="https://stackoverflow.com/questions/21066598/android-studio-0-4-2-gradle-project-sync-failed-error">This link</a> did not helps.</p>
  
  <p>One clue is that Gradle project sync in progress is flowing all the time , just after I restart the Studio.</p>
