Sau khi người dùng đăng nhập bằng Google, nếu bạn đã định cấu hình tính năng Đăng nhập bằng Google bằng tham số DEFAULT_SIGN_IN hoặc phương thức requestProfile, thì bạn có thể truy cập vào thông tin hồ sơ cơ bản của người dùng. Nếu đã định cấu hình tính năng Đăng nhập bằng Google bằng phương thức requestEmail, bạn cũng có thể lấy địa chỉ email của người đó.
Để biết thêm dữ liệu hồ sơ có thể có, hãy xem GoogleSignInAccount.
Xin lưu ý rằng bất kỳ trường hồ sơ nào cũng có thể là null, tuỳ thuộc vào phạm vi mà bạn yêu cầu và thông tin có trong hồ sơ của người dùng.

To ensure the continued security and usability of your app, [migrate\n| to Credential Manager](https://developer.android.com/training/sign-in/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.\n\nAfter you have signed in a user with Google, if you [configured Google Sign-In](/identity/sign-in/android/legacy-sign-in#configure_google_sign-in_and_the_googlesigninclient_object),\nwith the `DEFAULT_SIGN_IN` parameter or the `requestProfile` method, you can\naccess the user's basic profile information. If you configured Google Sign-In\nwith the `requestEmail` method, you can also get their email address.\n| **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\n| ID token to your backend server](/identity/sign-in/android/backend-auth) and validate the token on the server, or use the [server auth code flow](/identity/sign-in/android/offline-access).\n\nBefore you begin\n----------------\n\n- [Configure your Android Studio project](/identity/sign-in/android/legacy-start-integrating)\n- [Integrate Google Sign-In into your app](/identity/sign-in/android/legacy-sign-in)\n\nRetrieve profile information for a signed-in user\n-------------------------------------------------\n\nUse the `GoogleSignIn.getLastSignedInAccount` method to request profile\ninformation for the currently signed in user. \n\n GoogleSignInAccount acct = GoogleSignIn.getLastSignedInAccount(getActivity());\n if (acct != null) {\n String personName = acct.getDisplayName();\n String personGivenName = acct.getGivenName();\n String personFamilyName = acct.getFamilyName();\n String personEmail = acct.getEmail();\n String personId = acct.getId();\n Uri personPhoto = acct.getPhotoUrl();\n }\n\n| **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.\n\nFor additional profile data that might be available, see\n[`GoogleSignInAccount`](/android/reference/com/google/android/gms/auth/api/signin/GoogleSignInAccount).\nNote that any of the profile fields can be `null`, depending on which scopes\nyou requested and what information the user's profile includes."]]
