Cómo configurar un proyecto de la Consola de APIs de Google
Para utilizar la muestra, debes configurar un proyecto de la Consola de APIs de Google con un cliente de Android
y un cliente de aplicación web:
Abre un proyecto existente en la Consola de APIs o crea uno si
si todavía no tienes uno.
En la página de la pantalla de consentimiento de OAuth, asegúrate de que toda la información esté completa.
preciso.
En la página Credenciales, crea un ID de cliente de tipo Android. El nombre del paquete de la app de ejemplo es com.google.samples.quickstart.signin. También deberás proporcionar el
hash SHA-1 de la huella digital de tu certificado de firma. Consulta
Autenticación de tu cliente para obtener información.
En la página Credenciales, crea un ID de cliente de tipo aplicación web. Puedes salir
los campos Orígenes autorizados de JavaScript y URI de redireccionamiento autorizados en blanco En esta Web
el ID de cliente es obligatorio según el IdTokenActivity de la muestra y
Ejemplos de ServerAuthCodeActivity. En una aplicación real, este ID de cliente
representan el servidor de backend de tu app.
Copia y pega el ID de cliente en el archivo strings.xml de tu proyecto:
Ahora está todo listo para compilar la muestra y ejecutarla desde Android Studio.
Compila la muestra, haz clic en el botón de ejecución y selecciona un dispositivo o emulador conectado con la versión más reciente de los Servicios de Google Play.
Cómo funciona
La aplicación compila un GoogleSignInClient y especifica las opciones de acceso que necesita. Luego, cuando se hace clic en el botón de acceso, la aplicación inicia el intent de acceso, que le solicita al usuario que acceda con una Cuenta de Google.
// 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();
// Build a GoogleSignInClient with the options specified by gso.mGoogleSignInClient=GoogleSignIn.getClient(this,gso);

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?
