사용자 인증 정보 페이지에서 웹 애플리케이션 유형 클라이언트 ID를 만듭니다. 나갈 수 있습니다.
승인된 JavaScript 출처 및 승인된 리디렉션 URI 필드가 비어 있습니다 이 웹 클라이언트 ID는 샘플의 IdTokenActivity 및 ServerAuthCodeActivity 예시에서 필요합니다. 실제 앱에서 이 클라이언트 ID는
앱의 백엔드 서버를 나타냅니다.
샘플을 빌드하고 실행 버튼을 클릭한 후 연결된
최신 버전의 Google Play 서비스가 설치된 기기 또는 에뮬레이터가 필요합니다.
작동 방식
애플리케이션은 GoogleSignInClient를 빌드하고
변경할 수 있습니다. 그런 다음 로그인 버튼을 클릭하면 애플리케이션이 로그인 인텐트를 시작하여 사용자에게 Google 계정으로 로그인하라는 메시지를 표시합니다.

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\nUse our Android sample app to see how Sign-In works, or\n[add Sign-In to your existing app](/identity/sign-in/android/legacy-start-integrating).\n\n**Required:** The latest versions of\n[Android Studio](//developer.android.com/sdk/) and\n[Google Play Services](//developer.android.com/sdk/installing/adding-packages.html).\n\nGet the project\n---------------\n\nIf this is your first time using a Google services sample,\ncheck out the google-services repository. \n\n```\n$ git clone https://github.com/googlesamples/google-services.git\n```\n\nOpen Android Studio.\n\nSelect **File \\\u003e Open** , browse to where you cloned the\n`google-services` repository, and open\n`google-services/android/signin`.\n\nConfigure a Google API Console project\n--------------------------------------\n\nTo use the sample, you need to configure a Google API Console project with an Android client and a Web application client:\n\n1. Open an existing project in the [API Console](https://console.cloud.google.com/), or create a project if you don't already have one.\n2. On the OAuth consent screen page, make sure all of the information is complete and accurate.\n3. On the Credentials page, create an **Android** type client ID. The package name for the sample app is `com``.google``.samples``.quickstart``.signin`. You will also need to provide the SHA-1 hash from your signing certificate fingerprint. See [Authenticating Your Client](/android/guides/client-auth) for information.\n4. On the Credentials page, create a **Web application** type client ID. You can leave the Authorized JavaScript Origins and Authorized redirect URIs fields blank. This web client ID is required by the sample's `IdTokenActivity` and `ServerAuthCodeActivity` examples. In a real app, this client ID would represent your app's backend server.\n5.\n Copy and paste the client ID into your project's `strings.xml` file:\n\n ```\n \u003cstring name=\"server_client_id\"\u003eYOUR_SERVER_CLIENT_ID\u003c/string\u003e\n ```\n\nRun the sample\n--------------\n\nNow you're ready to build the sample and run it from Android Studio.\n\nBuild the sample and click the run button and select a connected\ndevice or emulator with the latest version of Google Play services.\n\nHow it works\n------------\n\nThe application builds a `GoogleSignInClient`, specifying\nthe sign-in options it needs. Then, when the sign-in button is\nclicked, the application starts the sign-in intent, which prompts the\nuser to sign in with a Google account. \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.\nGoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)\n .requestEmail()\n .build();\n``` \n\n```scilab\n// Build a GoogleSignInClient with the options specified by gso.\nmGoogleSignInClient = GoogleSignIn.getClient(this, gso);\n``` \n\n```scdoc\nprivate void signIn() {\n Intent signInIntent = mGoogleSignInClient.getSignInIntent();\n startActivityForResult(signInIntent, RC_SIGN_IN);\n}\n```\n\nNext steps\n----------\n\nIf you want to see how you can implement Google Sign-In in\nyour own app, take a look at our implementation guide.\n\n[Add Sign-In to your app](/identity/sign-in/android/legacy-start-integrating)\n\nDid you have a good experience?
