title: Duplicated element in AndroidManifest.xml with Cordova
body: <p>The build process ends with the following error:</p>
  
  <pre><code>BUILD FAILED in 3s
  (node:8976) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: cmd: Command failed with exit code 1 Error output:
      \platforms\android\app\src\main\AndroidManifest.xml:20:5-60 Error:
              Element uses-feature#android.hardware.camera at AndroidManifest.xml:20:5-60 duplicated with element declared at AndroidManifest.xml:19:5-84
  </code></pre>
  
  <p>The problem is that i have these two lines in my AndroidManifest.xml:</p>
  
  <pre><code>&lt;uses-feature android:name="android.hardware.camera" android:required="true" /&gt;
  &lt;uses-feature android:name="android.hardware.camera" /&gt;
  </code></pre>
  
  <p>The only plugin installed is <em>phonegap-plugin-barcodescanner</em> (version 7.0.2) and here are the versions used:</p>
  
  <ul>
  <li>Cordova: 8.0.0 </li>
  <li>Android: 7.0.0</li>
  </ul>
  
  <p>How can I remove the duplicated entry in the XML file? Even if I remove it manually it obviously comes back after the next build process.</p>
