Getting Profile Information

AI-generated Key Takeaways

• Google Sign-In for Android is outdated and developers should migrate to Credential Manager for enhanced security and user experience, except for Wear OS 3, 4, and 5.0 which requires continued use of Google Sign-In for Android until Credential Manager support is available.

• After signing in, developers can access basic user profile information, but are strongly advised against using email or user ID for backend server communication; instead, utilize user ID tokens or server auth code flow for security.

• To get started, developers need to configure their Android Studio project and integrate Google Sign-In into their app before retrieving user profile data.

• User profile information can be retrieved using GoogleSignIn.getLastSignedInAccount but email addresses should not be used for user identification due to potential changes, instead rely on the account's ID for consistent identification.

Warning: Google Sign-In for Android is outdated and no longer supported. To ensure the continued security and usability of your app, migrate to Credential Manager today. Credential Manager supports passkey, password, and federated identity authentication (such as Sign-in with Google), stronger security, and a more consistent user experience. For Wear developers: Credential Manager will be supported in Wear OS 5.1 and later on selected watches. Developers actively supporting Wear OS 3, 4 and 5.0 devices with Sign in with Google should continue using Google Sign-in for Android for your Wear applications. Sign in with Google support will be available on Credential Manager APIs for these versions of WearOS at a later date.

After you have signed in a user with Google, if you configured Google Sign-In, with the DEFAULT_SIGN_IN parameter or the requestProfile method, you can access the user's basic profile information. If you configured Google Sign-In with the requestEmail method, you can also get their email address.

Important: Do not use a user's email address or user ID to communicate the currently signed-in user to your app's backend server. Instead, send the user's ID token to your backend server and validate the token on the server, or use the server auth code flow.

Before you begin

• Configure your Android Studio project
• Integrate Google Sign-In into your app

Retrieve profile information for a signed-in user

Use the GoogleSignIn.getLastSignedInAccount method to request profile information for the currently signed in user.

GoogleSignInAccount acct = GoogleSignIn.getLastSignedInAccount(getActivity());
if (acct != null) {
  String personName = acct.getDisplayName();
  String personGivenName = acct.getGivenName();
  String personFamilyName = acct.getFamilyName();
  String personEmail = acct.getEmail();
  String personId = acct.getId();
  Uri personPhoto = acct.getPhotoUrl();
}

Note: A Google account's email address can change, so don't use it to identify a user. Instead, use the account's ID, which you can get on the client with GoogleSignInAccount.getId, and on the backend from the sub claim of the ID token.

For additional profile data that might be available, see GoogleSignInAccount. Note that any of the profile fields can be null, depending on which scopes you requested and what information the user's profile includes.
