  <p>I have done extensive research in order to fix the issue but my efforts have been in vain. So far I have attempted to:</p>
  
  <ul>
  <li>Create new projects.</li>
  <li>Import projects from Eclipse</li>
  <li>Reinstall the JDK </li>
  <li>Reinstall the Android SDK</li>
  <li>Wipe all relevant Android Studio data (including Gradle).</li>
  </ul>
  
  <p>I am currently running Java Version 1.8.0_25 on Mac OSX Lion and building this app for Android Lollipop. Android Studio is currently on v1.0.1</p>
  
  <p>Any project that is run from ADT works correctly without the above error.</p>
