title: After installing Android ADT 14: "R cannot be resolved"
body: <p>After updating to ADT 14, my project which formerly built fine now is full of errors. Everywhere I reference "R" (R.string.mystring, etc.) it says "R cannot be resolved".</p>
  
  <p>I do not have android.R imported anywhere.</p>
  
  <p>There is nothing in my "gen" folder.</p>
  
  <p>"Cleaning" the project just revealed ALL the places I reference "R" by flagging them with an error.</p>
  
  <p>Any suggestions?</p>
