Weird error message:
Gradle: A problem occurred configuring project ':App'.
> Failed to notify project evaluation listener.
> Could not resolve all dependencies for configuration ':App:_DefaultFlavorDebugCompile'.
> Could not find any version that matches com.android.support:appcompat-v7:+.

If this happens, just go to Tools -> Android -> Android SDK Manager, then check “Android Support Repository” and “Android Support Library” under “Extra” and install them. That should take care of the error.
