title: Android: Error when many package use R.java
body: <p>I have two package, for example, <code>packageA</code> and <code>packageB</code>.
  in packageA I has a class named <code>classA</code> that take resource from <code>R.java</code>: example: </p>
  
  <pre><code>TextView textView = (TextView) findViewById(R.id.textView);
  </code></pre>
  
  <p>same with package B. I has a class named <code>classB</code> that take resource from <code>R.java</code></p>
  
  <pre><code>EditText editText = (EditText) findViewById(R.id.EditText);
  </code></pre>
  
  <p>When I want android to run <code>classB</code>, I must change <code>Android Manifest file</code>, change default package from <code>com.packageA</code> to <code>com.packageB</code>, so classA will be notice error at above line. The same when I reverse.</p>
  
  <p>So, How can I fixed this problem: use multi packages and many of them use <code>Resource data</code>. Please help me.</p>
  
  <p>thanks :)</p>
