title: RecyclerView is missing
body: <p>I just installed the new SDK tools (Android L Developer Preview), and I'm trying to use <code>RecyclerView</code> but it seems to be missing.</p>
  
  <p>From my understanding I should include the <code>v7</code> support library, but I can't seem to do that...</p>
  
  <p>I can't seem to find the v7 library in the SDK folder (I did install the Android Support Library from the SDK Manager).</p>
