This class is deprecated.
The APIs in CredentialsClient are deprecated. Instead, use SignInClient.getPhoneNumberHintIntent(GetPhoneNumberHintIntentRequest) to request for phone number hints.

Parameters for requesting the display of the hint picker, via getHintPickerIntent(). Instances can be created using HintRequest.Builder. For a typical application that supports password based authentication and Google sign-in, the CredentialRequest would look like:

HintRequest request = new HintRequest.Builder()
         .setEmailAddressIdentifierSupported(true)
         .setAccountTypes(IdentityProviders.GOOGLE)
         .build();
