title: How to update gradle in android studio?
body: <p>I installed Android Studio 0.1.9.  Today I got and update to version 0.2 and of course I updated. After the installation I restarted Android Studio but now I get this message:</p>
  
  <blockquote>
    <p>Project is using an old version of the Android Gradle plug-in. The
    minimum supported version is 0.5.0. Please update the version of the
    dependency 'com.android.tools.build:gradle'</p>
  </blockquote>
  
  <p><strong>How do I do that? I can't find any update tools for the gradle plugin in android studio.</strong></p>
