Detach Android App, stand-alone build fail.

[jb9229]

Hi~

Now I can’t build stand-alone android app~

I just did:

1. Create new project(Expo XDE, Tab Navigation project)
2. Detach android app(commandline → exp detach)
3. command: react-native run-android

but fail message here:

I solved problem, i didn’t understand expo doc

ㅠ.ㅠ
