title: ADT Plugin disappeared in Eclipse
body: <p>..I was trying to install the Google Cloud Messaging for Android Library, from the Extra in Android SDK Manager. </p>
  
  <p>Since it did not appear, I updateded the Android SDK Tools and the Android SDK Platform-Tools to the last release (as shown here: <a href="https://stackoverflow.com/questions/11241756/how-google-cloud-messaging-service-in-android-works">How Google Cloud Messaging Service in Android Works?</a>).</p>
  
  <p>Once updated both, I still could not find any Extras--> Google Cloud Messaging for Android Library (just "Intel Hardware Accelerated Execution Manager"). So I updated Eclipse (version 3.6) too (Help->Check for Updates), but nothing happened except for the fact that <strong>the ADT plugin was not there anymore</strong>: no Android menu under Preferences, no possibilty to create Android projects and so on.</p>
  
  <p>I uninstelled the plugin, removed the files from the plugin directory, installed another version of Eclipse (3.8) with the addition of the plugin but <strong>nothing changed</strong>.</p>
  
  <p>Any ideas?</p>
  
  <p>I'm working on a Mac OS X Leopard.</p>
