 <p>I fixed it by doing the following: <em>(this was done using the ADT version of Eclipse, but should be applicable)</em></p> <ul> <li>Project Properties > Java Build Path > Libraries (tab) <ul> <li>Remove each Library</li> <li>Then click Add Library </li> <li>Select the Android Classpath Container</li> <li>Click Next or Finish</li> </ul></li> </ul>
