Answer 1

If R is not genereated correctly make sure none of ur java or xml files got error in them. Try Clean ur project.

Answer 2

Really annoying error, I've just had a very similar thing and wanted to re-iterate the importance of checking your XML files for anything odd! In the end mine was an activity that wasn't even in use anymore so going through and 'pruning' your project of obsolete files can help
