title: Eclipse giving error, missing R.java file after recent update
body: <p>I have updated my <code>SDK</code> and <code>ADT</code> to the latest version, I have also update the <code>Eclipse</code> to <code>Kepler</code> the latest one after <code>Juno</code>. </p>
  
  <p>My <code>ADT</code> version is <code>22.0</code>. After this update when I create a new project, I'm getting error, stating <code>R cannot be resolved to a variable</code>. I have imported <code>import android.R;</code>, but it is showing as unused import stating <code>Don't include android.R here; use a fully qualified name for each usage instead</code>. </p>
  
  <p>Same thing is happening with Mac OS also with the latest update. I have tried renaming <code>activity_main.xml</code> to other name, but still my <code>R.java</code> is not generated. </p>
  
  <p>Tried all the things which are possible. Cleaned the project, build the whole workspace. Nothing helping.</p>
  
  <p>I think <code>ADT</code> or <code>Eclipse</code> compatibility is having problem after the update.</p>
  
  <p>I have updated my whole SDK, here is the screenshot, but same problem is there.</p>
