title: The sample projects mentioned in Android Developer Official website cannot be found
body: <p>I have been reading the Android official <a href="http://developer.android.com/guide/topics/graphics/2d-graphics.html#on-view" rel="nofollow noreferrer">Canvas &amp; Drawable</a> document, there it mentioned a sample project :</p>
  
  <pre><code>For a sample application, see the Snake game, in the SDK samples folder: &lt;your-sdk-directory&gt;/samples/Snake/. 
  </code></pre>
  
  <p>I opened my Android Studio 1.0.1, chose <strong>File --> Import Sample ...</strong> , but I can not find the sample project from the window. </p>
  
  <p>In the document, it also mentioned another sample project:</p>
  
  <pre><code>For a sample application, see the Lunar Lander game, in the SDK samples folder: &lt;your-sdk-directory&gt;/samples/LunarLander/
  </code></pre>
  
  <p>I am not able to find it either. Why the document mentioned samples are not available in Android Studio "<strong>Import samples...</strong>" option? </p>
  
  <p>(I opened my SDK manager double checked that I have installed all the samples from API 15 to API 22.)</p>
