title: Starting the Android emulator in SDK tools, revision 12
body: <p>I updated the Android SDK tools from revision 11 to revision 12, and the emulator now fails to start.  When I try to run emulator.exe, I get:</p>
  
  <blockquote>
    <p>invalid command-line parameter: Files\Android\android-sdk\tools/emulator-arm.exe.<br>
    Hint: use '@foo' to launch a virtual device named 'foo'.<br>
    please use -help for more information</p>
  </blockquote>
  
  <p>The path to emulator.exe is <em>C:\Program Files\Android\android-sdk\tools</em>.</p>
  
  <p>How do I fix it?</p>
