หากต้องการผสานรวมการลงชื่อเข้าใช้ด้วย Google เข้ากับแอป Android ให้กำหนดค่าการลงชื่อเข้าใช้ด้วย Google และ
เพิ่มปุ่มลงในเลย์เอาต์ของแอปที่จะเริ่มขั้นตอนการลงชื่อเข้าใช้
ก่อนเริ่มต้น
กำหนดค่าโปรเจ็กต์คอนโซล Google API และตั้งค่าโปรเจ็กต์ Android Studio
กำหนดค่า Google Sign-In และออบเจ็กต์ GoogleSignInClient
ในonCreateเมธอดของกิจกรรมการลงชื่อเข้าใช้ ให้กำหนดค่าการลงชื่อเข้าใช้ด้วย Google เพื่อ
ขอข้อมูลผู้ใช้ที่แอปของคุณต้องการ ตัวอย่างเช่น หากต้องการกำหนดค่า
การลงชื่อเข้าใช้ด้วย Google เพื่อขอรหัสและข้อมูลโปรไฟล์พื้นฐานของผู้ใช้ ให้สร้างออบเจ็กต์ GoogleSignInOptions
ที่มีพารามิเตอร์ DEFAULT_SIGN_IN หากต้องการขออีเมลของผู้ใช้ด้วย ให้สร้างออบเจ็กต์ GoogleSignInOptions โดยใช้ตัวเลือก requestEmail
// Configure sign-in to request the user's ID, email address, and basic// profile. ID and basic profile are included in DEFAULT_SIGN_IN.GoogleSignInOptionsgso=newGoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN).requestEmail().build();
หากต้องการขอขอบเขตเพิ่มเติมเพื่อเข้าถึง Google API ให้ระบุขอบเขตเหล่านั้นด้วย requestScopes
เมื่อลงชื่อเข้าใช้ ให้ขอเฉพาะขอบเขตที่จำเป็นเพื่อให้แอปทำงานได้ขั้นต่ำ เพื่อให้ผู้ใช้ได้รับประสบการณ์ที่ดีที่สุด ขอขอบเขตเพิ่มเติมเฉพาะเมื่อจำเป็นเท่านั้น เพื่อให้ผู้ใช้เห็นหน้าจอคำยินยอมในบริบทของการดำเนินการที่ผู้ใช้ทำ

Credential Manager\n| supports passkey, password, and federated identity authentication (such as\n| Sign-in with Google), stronger security, and a more consistent user\n| experience.\n|\n| **For Wear developers:** Credential Manager will be supported in Wear OS\n| 5.1 and later on selected watches. Developers actively supporting Wear OS 3, 4\n| and 5.0 devices with Sign in with Google should continue using Google Sign-in\n| for Android for your Wear applications. Sign in with Google support will be\n| available on Credential Manager APIs for these versions of WearOS at a later\n| date.\n\nTo integrate Google Sign-In into your Android app, configure Google Sign-In and\nadd a button to your app's layout that starts the sign-in flow.\n\nBefore you begin\n----------------\n\nConfigure a Google API Console project and set up your Android Studio project.\n\nConfigure Google Sign-in and the GoogleSignInClient object\n----------------------------------------------------------\n\n1. In your sign-in activity's `onCreate` method, configure Google Sign-In to\n request the user data required by your app. For example, to configure\n Google Sign-In to request users' ID and basic profile information, create a\n [`GoogleSignInOptions`](https://developers.google.com/android/reference/com/google/android/gms/auth/api/signin/GoogleSignInOptions.Builder.html#GoogleSignInOptions.Builder())\n object with the `DEFAULT_SIGN_IN` parameter. To request users' email\n addresses as well, create the `GoogleSignInOptions` object with the\n `requestEmail` option.\n\n ```carbon\n // Configure sign-in to request the user's ID, email address, and basic\n // profile. ID and basic profile are included in DEFAULT_SIGN_IN.\n GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)\n .requestEmail()\n .build();\n ```\n\n If you need to request additional scopes to access Google APIs, specify them\n with [`requestScopes`](https://developers.google.com/android/reference/com/google/android/gms/auth/api/signin/GoogleSignInOptions.Builder.html#requestScopes(com.google.android.gms.common.api.Scope,%20com.google.android.gms.common.api.Scope...)).\n For the best user experience, on sign-in, only request the scopes that are\n required for your app to minimally function. Request any additional scopes\n only when you need them, so that your users see the consent screen in the\n context of an action they performed.\n See [Requesting Additional Scopes](https://developers.google.com/identity/sign-in/android/additional-scopes).\n2. Then, also in your sign-in activity's `onCreate` method, create a\n `GoogleSignInClient` object with the options you specified.\n\n ```scilab\n // Build a GoogleSignInClient with the options specified by gso.\n mGoogleSignInClient = GoogleSignIn.getClient(this, gso);\n ```\n\nCheck for an existing signed-in user\n------------------------------------\n\nIn your activity's `onStart` method, check if a user has already signed in to\nyour app with Google. \n\n```scilab\n// Check for existing Google Sign In account, if the user is already signed in\n// the GoogleSignInAccount will be non-null.\nGoogleSignInAccount account = GoogleSignIn.getLastSignedInAccount(this);\nupdateUI(account);\n```\n\nIf `GoogleSignIn.getLastSignedInAccount` returns a `GoogleSignInAccount` object\n(rather than `null`), the user has already signed in to your app with Google.\nUpdate your UI accordingly---that is, hide the sign-in button, launch your\nmain activity, or whatever is appropriate for your app.\n\nIf `GoogleSignIn.getLastSignedInAccount` returns `null`, the user has not yet\nsigned in to your app with Google. Update your UI to display the Google Sign-in\nbutton.\n| **Note:** If you need to detect changes to a user's auth state that happen outside your app, such as access token or ID token revocation, or to perform cross-device sign-in, you might also call `GoogleSignInClient.silentSignIn` when your app starts.\n\nAdd the Google Sign-in button to your app\n-----------------------------------------\n\n1.\n Add the [`SignInButton`](https://developers.google.com/android/reference/com/google/android/gms/common/SignInButton)\n in your application's layout:\n\n \u003ccom.google.android.gms.common.SignInButton\n android:id=\"@+id/sign_in_button\"\n android:layout_width=\"wrap_content\"\n android:layout_height=\"wrap_content\" /\u003e\n\n2. **Optional** : If you are using the default sign-in button graphic instead of\n providing your own sign-in button assets, you can customize the button's\n size with the [`setSize`](https://developers.google.com/android/reference/com/google/android/gms/common/SignInButton.html#setSize(int))\n method.\n\n ```scilab\n // Set the dimensions of the sign-in button.\n SignInButton signInButton = findViewById(R.id.sign_in_button);\n signInButton.setSize(SignInButton.SIZE_STANDARD);\n ```\n3. In the Android activity (for example, in the `onCreate` method), register\n your button's `OnClickListener` to sign in the user when clicked:\n\n findViewById(R.id.sign_in_button).setOnClickListener(this);\n\nStart the sign-in flow\n----------------------\n\n1.\n In the activity's `onClick` method, handle sign-in button taps by creating a\n sign-in intent with the [`getSignInIntent`](https://developers.google.com/android/reference/com/google/android/gms/auth/api/signin/GoogleSignInClient#getSignInIntent())\n method, and starting the intent with `startActivityForResult`.\n\n @Override\n public void onClick(View v) {\n switch (v.getId()) {\n case R.id.sign_in_button:\n signIn();\n break;\n // ...\n }\n }\n\n ```scdoc\n private void signIn() {\n Intent signInIntent = mGoogleSignInClient.getSignInIntent();\n startActivityForResult(signInIntent, RC_SIGN_IN);\n }\n ```\n\n Starting the intent prompts the user to select a Google Account to sign in\n with. If you requested scopes beyond `profile`, `email`, and `openid`, the\n user is also prompted to grant access to the requested resources.\n2. After the user signs in, you can get a [`GoogleSignInAccount`](https://developers.google.com/android/reference/com/google/android/gms/auth/api/signin/GoogleSignInAccount.html)\n object for the user in the activity's `onActivityResult` method.\n\n ```transact-sql\n @Override\n public void onActivityResult(int requestCode, int resultCode, Intent data) {\n super.onActivityResult(requestCode, resultCode, data);\n\n // Result returned from launching the Intent from GoogleSignInClient.getSignInIntent(...);\n if (requestCode == RC_SIGN_IN) {\n // The Task returned from this call is always completed, no need to attach\n // a listener.\n Task\u003cGoogleSignInAccount\u003e task = GoogleSignIn.getSignedInAccountFromIntent(data);\n handleSignInResult(task);\n }\n }\n ```\n\n The `GoogleSignInAccount` object contains information about the signed-in\n user, such as the user's name. \n\n ```css+lasso\n private void handleSignInResult(Task\u003cGoogleSignInAccount\u003e completedTask) {\n try {\n GoogleSignInAccount account = completedTask.getResult(ApiException.class);\n\n // Signed in successfully, show authenticated UI.\n updateUI(account);\n } catch (ApiException e) {\n // The ApiException status code indicates the detailed failure reason.\n // Please refer to the GoogleSignInStatusCodes class reference for more information.\n Log.w(TAG, \"signInResult:failed code=\" + e.getStatusCode());\n updateUI(null);\n }\n }\n ```\n\n You can also get the user's email address with [`getEmail`](https://developers.google.com/android/reference/com/google/android/gms/auth/api/signin/GoogleSignInAccount.html#getEmail()),\n the user's Google ID (for client-side use) with [`getId`](https://developers.google.com/android/reference/com/google/android/gms/auth/api/signin/GoogleSignInAccount.html#getId()),\n and an ID token for the user with [`getIdToken`](https://developers.google.com/android/reference/com/google/android/gms/auth/api/signin/GoogleSignInAccount.html#getIdToken()).\n If you need to pass the currently signed-in user to a backend server,\n [send the ID token to your backend server](https://developers.google.com/identity/sign-in/android/backend-auth)\n and validate the token on the server."]]
