title: Eclipse DDMS not showing Emulator on restart
body: <p>I'm running Eclipse: Helios. Here's the issue. When I leave my Android Emulator running for about 20 minutes while I'm programming, if I try to install and run my application, I receive this error in the console:</p>
  <blockquote>
  <p>[2011-07-12 12:27:55 - DatePrinter] Failed to install DatePrinter.apk
  on device 'emulator-5554': Connection refused: connect</p>
  <p>[2011-07-12 12:27:55 - DatePrinter] java.net.ConnectException:
  Connection refused: connect</p>
  <p>[2011-07-12 12:27:55 - DatePrinter] Launch canceled!</p>
  </blockquote>
  <p>If I close the emulator and run the project again, a new emulator launches and the console shows the emulator starting but the app does not install and the emulator does not show up in DDMS.</p>
  <p>If I go to the terminal and type in <code>adb devices</code>, I get this error message</p>
  <blockquote>
  <p>ADB Server didn't ACK</p>
  <p>*failed to start daemon*</p>
  <p>error cannot connect to daemon</p>
  </blockquote>
  <p>The only way I can fix it that I've found is to close eclipse, kill the adb.exe process and restart eclipse.</p>
  <p>Any ideas what could be causing this error/how to debug it?</p>
  <p><strong>Edit</strong>: Starting the emulator through SDK manager does not yield any positive results either.</p>
  <p><strong>Edit 2</strong>: Running adb kill-server and adb start-server yields the same message &quot;ADB Server didn't ACK&quot; although it prints a <code>&quot;daemon not started, starting it now on port 5037&quot;</code> right before that.</p>
