GoogleSignInOptions.Builder

public Builder()

Default Builder for GoogleSignInOptions which starts with clean configuration.

If you are trying to implement Sign In, i.e. you want to get back user identity, you can start with new GoogleSignInOptions(GoogleSignInOptions.DEFAULT_SIGN_IN),

public Builder(@NonNull GoogleSignInOptions googleSignInOptions)

A Builder for GoogleSignInOptions which you can specify one of the default configurations Google (will) provide and make additional configurations based on it. e.g.DEFAULT_SIGN_IN.

@CanIgnoreReturnValue
public GoogleSignInOptions.Builder addExtension(GoogleSignInOptionsExtension extension)

Specifies additional sign-in options via the given extension.

public GoogleSignInOptions build()

Builds the GoogleSignInOptions object.

@CanIgnoreReturnValue
public GoogleSignInOptions.Builder requestEmail()

Specifies that email info is requested by your application. Note that we don't recommend keying user by email address since email address might change. Keying user by ID is the preferable approach.

@CanIgnoreReturnValue
public GoogleSignInOptions.Builder requestId()

Specifies that user ID is requested by your application.

@CanIgnoreReturnValue
public GoogleSignInOptions.Builder requestIdToken(String serverClientId)

Specifies that an ID token for authenticated users is requested. Requesting an ID token requires that the server client ID be specified.

@CanIgnoreReturnValue
public GoogleSignInOptions.Builder requestProfile()

Specifies that user's profile info is requested by your application.

@CanIgnoreReturnValue
public GoogleSignInOptions.Builder requestScopes(Scope scope, Scope[] scopes)

Specifies OAuth 2.0 scopes your application requests. See Scopes for more information.

@CanIgnoreReturnValue
public GoogleSignInOptions.Builder requestServerAuthCode(String serverClientId)

Specifies that offline access is requested. Requesting offline access requires that the server client ID be specified.

You don't need to use requestIdToken when you use this option. When your server exchanges the code for tokens, an ID token will be returned together (as long as you either use requestEmail or requestProfile along with your configuration).

The first time you retrieve a code, a refresh_token will be granted automatically. Subsequent requests will only return codes that can be exchanged for access token.

public GoogleSignInOptions.Builder requestServerAuthCode(
    String serverClientId,
    boolean forceCodeForRefreshToken
)

You don't need to use requestIdToken when you use this option. When your server exchanges the code for tokens, an ID token will be returned together (as long as you either use requestEmail or requestProfile along with this configuration).

@CanIgnoreReturnValue
public GoogleSignInOptions.Builder setAccountName(String accountName)
