title: Android emulator not starting at all
body: <p>Today I tried to launch my Android app from within eclipse but nothing happened. Everything worked fine yesterday. I tried a few things like adb kill-server, adb-start-server. At some point I got the "user data image is used by another emulator" error, so I went about deleting the .lock folders in the avd image but to no avail. </p>
  
  <p>I created a new avd and the emulator doesnt even start with this image. I tried to start it with </p>
  
  <pre><code>emulator -avd avdname
  </code></pre>
  
  <p>->nothing. No error. emulator.exe is running in Taskmanager. </p>
  
  <p>Windows 7
  Android SDK Tools, revision 7</p>
  
  <p><strong>Update:</strong> Now I know when I get the error </p>
  
  <blockquote>
    <p>emulator: ERROR: the user data image is used by another emulator. aborting</p>
  </blockquote>
  
  <p>it's when I try to run the application again after the emulator.exe is already dangling in Taksmanager.</p>
  
  <p><strong>Update:</strong> waited for 20mins. emulator.exe is just sitting there with 00:00:00 cpu time. </p>
