title: Android device appears offline despite plugging in USB and switching on USB debugging
body: <p>I'm trying to run my Android app on a Samsung Galaxy Ace. Despite plugging in the USB and enabling debugging, when I try to run the app, Eclipse prints out a message saying </p>
  
  <pre><code>[2012-07-14 22:56:19 - Cricket] Android Launch!
  [2012-07-14 22:56:19 - Cricket] adb is running normally.
  [2012-07-14 22:56:19 - Cricket] Performing nikhil.android.cricket.MainActivity activity launch
  [2012-07-14 22:56:19 - Cricket] No active compatible AVD's or devices found. Relaunch this configuration                     after connecting a device or starting an AVD.
  </code></pre>
  
  <p>I'd like to add that I've been trying a lot but am unable to do anything. I tried killing adb and restarting it. Same error. Also, I am able to run it instantly when I connect my friend's Samsung Galaxy Note. But it won't run on  my Samsung Galaxy Ace. I'd appreciate any help I can get on this.</p>
