title: android eclipse problem with R.java
body: <p>Suddenly my Android app is compiling with loads of errors in Eclipse.   When I use Project-Clean the console shows it processing until 'Writing symbols for class R'  then it pauses for  around a minute and finishes with 'Nothing to pre compile'   This behaviour follows adding several new strings to my strings.xml and replacing strings in the code with :-                          </p>
  
  <p>getResources().getString(R.string.name of string);</p>
  
  <p>Any ideas?   Would it be safe to delete the R.java file to force it to rebuild perhaps?</p>
