This class is deprecated.
The APIs in CredentialsClient are deprecated. Instead, use SignInClient.beginSignIn(BeginSignInRequest) to request for credentials.

Parameters for requesting a Credential, via CredentialsApi.request(com.google.android.gms.common.api.GoogleApiClient, CredentialRequest).

Instances can be created using CredentialRequest.Builder. For a typical application that supports password based authentication and Google sign-in, the CredentialRequest would look like:

CredentialRequest request = new CredentialRequest.Builder()
         .setAccountTypes(IdentityProviders.GOOGLE)
         .setPasswordLoginSupported(true)
         .build();
