Android Build a Simple Android App (2014) Getting Started with Android Running the Fun Facts Project

My emulator doesn't show up. Message dialog brings a 'Resource id cannot be an empty string (at 'id' with value' @+id/')

I've got a different version of Android Studio (1.1.0), and many widgets, buttons and dialogs are not the same as in video. I might miss something.

I've simply deleted problematic string and and everything work just fine.
