I have the script and drive apis enabled and also have checked the credentials and all seems ok. Both the script and android clients are in the same project and The scriptId used in the project comes from the published script. This is a generic error. The project does not exist. Any suggestions? I saw one post that indicated a typo in the app name might cause this, but not much else.
