Aaaargh! I don\'t know what\'s going on, but suddenly I can\'t launch my app. I\'m using IntelliJ and I keep getting this error. I thought maybe there was a typo somewhere i
Also double check the package and activity name. I got a similar error caused by a missing dot in front of the activity name (e.g. "package.Activity" instead of ".package.Activity" ). IntelliJ didn't mark it as wrong so it was easily overlooked.
