title: Zxing library cannot be resolved
body: <p>I am developing app with zxing library. I imported the <code>zxing</code> project into my work place. When i importing there were some problems i faced.</p>
  
  <ol>
  <li>Compile the project by <code>java 1.7</code>. I done it.</li>
  <li><code>CameraConfigurationUtils</code> was missing. I copied from the <code>library source</code>.</li>
  <li><code>Resource id's</code> cannot be used to check in the <code>switch case</code>. I changed it to <code>if else</code>. </li>
  </ol>

  1. <code>emailResult.getTos()</code> was not resolved in <code>EmailAddressResultHandler</code> 
  2. Then i built the project there comes the problem <strong><code>R.java</code></strong> cannot be resolved throughout my application.</p>
