also line compiling successfully!

compile 'com.github.satyan:sugar:1.4' 

i don't know why fatal error occurred? mistake?

sync gradle , build.

just download package not generate com.orm.sugarapp. gradle sync generate class , before syncing, appears lint error in androidmanifest. unfortunately cannot captured compiler error , results in runtime error get.
