Class GoogleAuthorizationCodeFlow (2.1.2) 

public class GoogleAuthorizationCodeFlow extends AuthorizationCodeFlow

Thread-safe Google OAuth 2.0 authorization code flow that manages and persists end-user credentials.

This is designed to simplify the flow in which an end-user authorizes the application to access their protected data, and then the application has access to their data based on an access token and a refresh token to refresh that access token when it expires.

The first step is to call #loadCredential(String) based on the known user ID to check if the end-user's credentials are already known. If not, call #newAuthorizationUrl() and direct the end-user's browser to an authorization page. The web browser will then redirect to the redirect URL with a "code" query parameter which can then be used to request an access token using #newTokenRequest(String). Finally, use #createAndStoreCredential(TokenResponse, String) to store and obtain a credential for accessing protected resources.

The default for the approval_prompt and access_type parameters is null. For web applications that means "approval_prompt=auto&access_type=online" and for installed applications that means "approval_prompt=force&access_type=offline". To override the default, you need to explicitly call Builder#setApprovalPrompt(String) and Builder#setAccessType(String).
