I tried various forums but no luck I couldn't figure out what's wrong with it

I tried several options but still no luck I will try on eclipse just to see if there is something wrong with the Android studio and update the thread thanks for the help

The last time I had an error like this, I think it was something I changed in one of the many XML files. Dummy me didn't have a backup, rollback in place and I had to delete that activity and create it again. Better than a total wipe out.
