body: <p>How to determine an android device whether supports "android.hardware.camera.autofocus"?</p>
  
  <p>From where I can get a feature list supported by this android device?</p>
  
  <p>I want to use feature in my app, but I don't know if the phone supports or not.</p>
  
  <pre><code>&lt;uses-feature
      android:name="android.hardware.camera"
      &gt;
  &lt;/uses-feature&gt;
  &lt;uses-feature
      android:name="android.hardware.camera.autofocus"
      android:required="true"
      &gt;
  &lt;/uses-feature&gt;
  </code></pre>
