Configurar um projeto do Console de APIs do Google
Para usar o exemplo, você precisa configurar um projeto do Console de APIs do Google com um cliente Android
e um cliente de aplicativo da Web:
Abra um projeto no console da API ou crie um se ainda não tiver um.
Na página da tela de permissão OAuth, verifique se todas as informações estão completas e
precisos.
Na página "Credenciais", crie um ID do cliente do tipo Android. O nome do pacote do
app de exemplo é com.google.samples.quickstart.signin. Você também precisará fornecer o
O hash SHA-1 da impressão digital do certificado de assinatura. Consulte
Como autenticar seu cliente para mais informações.
Na página "Credenciais", crie um ID do cliente do tipo Aplicativo da Web. Você pode sair
os campos Origens JavaScript autorizadas e URIs de redirecionamento autorizados em branco. Este site
ID do cliente é exigido pelos atributos IdTokenActivity e
ServerAuthCodeActivity exemplos. Em um app real, esse ID do cliente
representam o servidor de back-end do app.
Copie e cole o ID do cliente no arquivo strings.xml do projeto:
Agora você já pode criar o exemplo e executá-lo no Android Studio.
Crie a amostra, clique no botão "Executar" e selecione um
dispositivo ou emulador com a versão mais recente do Google Play Services.
Como funciona
O aplicativo cria um GoogleSignInClient, especificando
as opções de login necessárias. Em seguida, quando o botão de login é
clicado, o aplicativo inicia a intent de login, que solicita que o
usuário faça login com uma Conta do 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 If 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 To 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 Now 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 The 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 If 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?
