title: Android Studio accuses Google Repository is not installed in the SDK Manager
body: <p>I am trying to add Google Maps on my Android project and I was following this instructions:
  <a href="http://developer.android.com/google/play-services/setup.html" rel="nofollow noreferrer">http://developer.android.com/google/play-services/setup.html</a></p>
  
  <p>However, when I try to add </p>
  
  <p><code>compile 'com.google.android.gms:play-services:5.0.77'</code> </p>
  
  <p>to my <code>build.gradle</code>, AndroidStudio says</p>
  
  <pre><code>Dependency on Play Services, but the SDK installation does not have the "Extras &gt; Google Repositories" installed. Open the SDK Manager and install it.
  </code></pre>
  
  <p>The problem is that I have it installed already:

  <p>I have already checked on File > Project Structure > Android SDK location and I am using the correct SDK path. </p>
  
  <p>Any ideas?</p>
