title: How to add requirement of having a back facing camera in Manifest File?
body: <p>I need to exclude devices which do not have a rear facing camera from installing the app. I am aware in AndoirdManifest.xml I can mention :- </p>
  
  <pre><code>&lt;uses-feature
          android:name="android.hardware.camera"
    android:required="true" /&gt;
  </code></pre>
  
  <p>But this will still allow devices with no back facing camera(but they do have front facing camera) to install the app.</p>
  
  <p>I read in android docs that we can mention subfeature requirement to have front facing camera</p>
  
  <pre><code>android:name="android.hardware.camera.front".
  </code></pre>
  
  <p>But is there a way I can mention the back facing camera as requirement. Something like </p>
  
  <pre><code>android:name="android.hardware.camera.back"
  </code></pre>
  
  <p>Also is there a way to test if this requirement will work before releasing it to play store. I tried to test this on emulators &amp; devices but the application always gets installed from the eclipse even when they don't have any camera at all.</p>
  
  <p>Thanks !!
