I had fixed my problem,by this solution..hope it will help:

check throughly all of the .xml files(in layout,in menu,in values .in drawable folders etc.),one of them may have some error,as this is the big reason to remove r.java file.If any xml file may have any error fix that error, then build your project again.. R.java again visible in "gen" folder
