title: Unsupported method: InstantRun.getRestartDexFile() - Android Studio
body: <p>I have Android Studio 2.0 Beta 6<br>
  and the Gradle version in build.gradle is <em>classpath 'com.android.tools.build:gradle:2.1.0-beta1'</em><br>
  (I updated it today only, earlier I was at gradle:2.0.0-alpha9).<br>
  Now when I try to Run my app I keep getting this  Message.</p>
  
  <blockquote>
    <p><em>UnsupportedMethodException<br>
    Unsupported method: InstantRun.getRestartDexFile().<br>
    The version of Gradle you connect to does not support that method.<br>
    To resolve the problem you can change/upgrade the target version of Gradle you connect.<br>
    Alternatively, you can ignore this exception and read other information from the model.</em></p>
  </blockquote>
  
  <p>Everything was running fine before the upgrade (including Instant Run).<br>
  Please help.</p>
