Configurare un progetto della console API di Google
Per utilizzare il Sample, devi configurare un progetto della console API di Google con un client Android
e un client di applicazione web:
Apri un progetto esistente nella console API o creane uno se non ne hai già uno.
Nella pagina della schermata di consenso OAuth, assicurati che tutte le informazioni siano complete e accurate.
Nella pagina Credenziali, crea un ID client di tipo Android. Il nome del pacchetto per
l'app di esempio è com.google.samples.quickstart.signin. Dovrai inoltre fornire
Hash SHA-1 dall'impronta digitale del certificato di firma. Consulta:
Autenticazione del cliente per ulteriori informazioni.
Nella pagina Credenziali, crea un ID client di tipo Applicazione web. Puoi lasciare vuoti i campi Origini JavaScript autorizzate e URI di reindirizzamento autorizzati. Questo ID client web è obbligatorio per gli esempi IdTokenActivity e
ServerAuthCodeActivity del sample. In un'app reale, questo ID client representerebbe il server di backend dell'app.
Copia e incolla l'ID client nel file strings.xml del progetto:
Ora è tutto pronto per creare l'esempio ed eseguirlo da Android Studio.
Crea l'esempio, fai clic sul pulsante Esegui e seleziona un
un emulatore o un dispositivo con la versione più recente di Google Play Services.
Come funziona
L'applicazione crea un GoogleSignInClient, specificando
le opzioni di accesso necessarie. Poi, quando viene fatto clic sul pulsante di accesso, l'applicazione avvia l'intent di accesso, che chiede all'utente di accedere con un Account 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?
