title: Strange CardView issue: ("Failed to find: com.android.support:cardview-v7:21.0.+" Error)
body: <p>I have Android 5.0 and the most current version of the Android Support Libraries (21.0.2). I am trying to access the CardView and the RecyclerViews in Android. When I add:</p>
  
  <pre><code>compile 'com.android.support:cardview-v7:21.0.+'
  compile 'com.android.support:recyclerview-v7:21.0.+'
  </code></pre>
  
  <p>to the app's build.gradle dependecies, I get the errors:</p>
  
  <pre><code>Failed to find: com.android.support:cardview-v7:21.0.+
  </code></pre>
  
  <p>and</p>
  
  <pre><code>Failed to find: com.android.support:recyclerview-v7:21.0.+
  </code></pre>
  
  <p>I'm not sure why this is. This is the only way I have seen people do it (and it's the way suggested on Google's website <a href="http://developer.android.com/training/material/lists-cards.html#Dependencies" rel="nofollow">here</a>). After this, I cannot make CardViews or RecyclerViews in my project.</p>
  
  <p>I have also checked my android sdk folder:</p>
  
  <pre><code>C: &gt; ... &gt; android-sdk &gt; extras &gt; android &gt; support &gt; v7
  </code></pre>
  
  <p>and both the 'cardview' and 'recyclerview' directories are there with all the files in them.</p>
  
  <p>I'm not sure why this is so...
  If you have any questions please ask and any suggestions or answers would be greatly appreciated!</p>
