DEVELOPMENT_URL in Ejected App

What should go in DEVELOPMENT_URL in file DetachBuildConstants.java after ejecting?

It is blank by default and this results in an error when running.

@nabeelshikder that file is auto generated and that value is based on what you have in AppConstants.java, string prop SHELL_APP_SCHEME - do a Build → Clean or restart AS

@helium, can you confirm if it works on your side?

I get the following crash on opening, it seems that the value is not automatically inserted:
