Conversion to Dalvik format failed with error 1

I started google android development today, after downloading SDK and loading it into eclipse just like how google guide “hello android” has listed.

no classfiles specified
Conversion to Dalvik format failed with error 1
pops up as I try to run it for the very first time.

How you fix it is
Go to Project -> Clean and it should solve the problem.

Good luck on your “Hello Android Application”
