  <pre><code>Failed to resolve: com.android.support:design-v7:23.0.0 
  </code></pre>
  
  <p>I have updated all skd tools required (like android support library, repository) but when i sync the project it shows Error. Even on clicking "Install Repository and sync project" nothing happens.</p>
  
  <p>I've checked other questions already but they did not work for me.</p>
