title: R cannot be resolved to a variable - Deleted Appcompat_v7
body: <p>Today I deleted by mistake appcompat_v7 and few of my apps got this error: </p>
  
  <pre><code>R cannot be resolved to a variable
  </code></pre>
  
  <p>I tried with importing my package name, but eclipse changes it by default to <code>import android.R;</code>
  Is there anything I can do? I did clean project several times it didn't work. </p>
