Strange console output when starting app: "Forcing GfxDevice: Null"

Question

My Unity app is successfully built, but it's not working.
I always see the strange console output below after the app starts.
What's going wrong?

Seems like server build. In your build setting menu, do you have the "Server Build" checkbox checked? If yes, un-check that and retry.
