title: Error "The connection to adb is down, and a severe error has occurred."
body: <p>I've spent days trying to launch any Android program. Even "Hello World" gives me the same error:</p>
  
  <blockquote>
    <p>"The connection to adb is down, and a severe error has occurred".</p>
  </blockquote>
  
  <p>I'm running Eclipse&nbsp;v3.5 (Galileo), Google APIs 2.2.8, on a Windows XP machine.</p>
  
  <p>I've used all the tricks I can find on the web: the command line "adb kill-server", the DDMS "reset ADB", I started the emulator both before and after Eclipse, and searched for ports being used by other programs.</p>
  
  <p>What is going on here? Is there a magic combination of versions of Eclipse, Java, ADB, emulator, and whatever else that works?</p>
