title: how can I auto-authenticate to a specific google account using java code?(auto-authenticate)
body: <p>I am trying to create an application that uses google drive as storage, this application is somehow private. however, I don't want it to ask me to log in not even once, I don't mind the application knowing the full credentials it needs to access the google drive it will use.
  In short, is there a way to auto-authenticate my app to fully access a certain google drive by saving the google account somewhere?</p>
