title: Install old system image with Android Tools R21
body: <p>I'm stumped after doing a fresh install of Android Development Tools r21. <a href="http://developer.android.com/sdk/index.html" rel="nofollow noreferrer">http://developer.android.com/sdk/index.html</a></p>
  
  <p>I've installed this and I am looking to create an AVD for Android 2.1 (API 7) to test some things, but I cannot find an option to install the Android 2.1 system image. In fact, nothing prior to Android 4.0 is an available system image for an AVD.</p>
  
  <p>I've installed the SDK Platform but it doesn't include the system image. Based on the <em>Official Add-on Sites</em>, I tried to go to <a href="https://dl-ssl.google.com/android/repository/sys-img.xml" rel="nofollow noreferrer">https://dl-ssl.google.com/android/repository/sys-img.xml</a> but this is essentially an empty XML file.</p>
  
  <p>I've also checked the ADT Known Issues <a href="http://tools.android.com/knownissues" rel="nofollow noreferrer">http://tools.android.com/knownissues</a></p>
  
  <p>Finally, from <a href="https://stackoverflow.com/questions/7877361/how-install-old-adt13-in-eclipse">How install old ADT13 in Eclipse</a> I gleaned the possible add-on site of <a href="https://dl-ssl.google.com/android/repository/repository.xml" rel="nofollow noreferrer">https://dl-ssl.google.com/android/repository/repository.xml</a>, but that doesn't pull anything into the SDK Manager either.</p>
  
  <p>Does anyone know how to get this working?</p>
