title: Select target API in the Android Studio layout design preview
body: <p>My application targets API 17 but the min Sdk version is the 8. In the layout design preview page I can se how my layout appears on an API 17 version, but if I click on the API selector drop down menu, I can't choose any other API level.
  Obviousely I can run my application in a 2.3 Android version and on a real device I can see the result, but is there a way to test in also in the design preview page?</p>
  
  <p>My manifest snippet:</p>
  
  <pre><code>    &lt;uses-sdk
      android:minSdkVersion="8"
      android:targetSdkVersion="17" /&gt;
  </code></pre>
