Public Methods

public Task<U2fPendingIntent> getRegisterIntent (RegisterRequestParams requestParams)

Creates a Task with U2fPendingIntent. When this Task object starts, it issues a U2F registration request, which is done once per U2F device per account for associating the new U2F device with that account. For example:


 Task result = mU2fApiClient.getRegisterIntent(registerRequestParams);
 ...
 result.addOnSuccessListener(
      new OnSuccessListener() {
        @Override
        public void onSuccess(U2fPendingIntent u2fPendingIntent) {
          if (u2fPendingIntent.hasPendingIntent()) {
            // Start a U2F registration request.
            u2fPendingIntent.launchPendingIntent(this, REGISTER_REQUEST_CODE);
          }
        }
      });
 result.addOnFailureListener(
     new OnFailureListener() {
       @Override
       public void onFailure(Exception e) {
         // Fail
       }
     }
Parameters
requestParams for the registration request
Returns
  • Task with PendingIntent to launch U2F registration request

public Task<U2fPendingIntent> getSignIntent (SignRequestParams requestParams)

      new OnSuccessListener() {
        @Override
        public void onSuccess(U2fPendingIntent u2fPendingIntent) {
          if (u2fPendingIntent.hasPendingIntent()) {
            // Start a U2F sign request.
            u2fPendingIntent.launchPendingIntent(this, SIGN_REQUEST_CODE);
          }
        }
      });
