Most of the newer Google APIs have quotas (like daily usage limits) and some even have billing support (where you get billed per API call). These quotas and billing are calculated per developer's project, and not on a per-end-user basis, so Google needs to know which app to assign your API usage.

API clients using Google's OAuth 2.0 are typically required to register and get a client ID and client secret.

This client ID and client secret are returned by the Google APIs console: code.google.com/apis/console.

You then use these values in your application, and this identifies your app and allows Google to assign your API usage to your developer account/project.

In the AccountManger interface you're using, there is no client ID passed by your app, so Google can't identify which developer account/project's quota to deduct for usage. It also doesn't know that the API has been properly enabled (TOS accepted, etc) by you as a developer. That's why it's asking you to "please sign up" and saying the "Daily limit exceeded" (as the unregistered limit is zero requests for many APIs).

In this scenario, it is necessary for you to pass the "key" value as you did in order to access APIs with OAuth 2.0 tokens retrieved from the AccountManager.
