我正在开发一个Android应用程序,我只想在不创建用户帐户的情况下验证手机号码.可能吗？我使用以下代码

   private void startPhoneNumberVerification(String phoneNumber) {

    PhoneAuthProvider.getInstance().verifyPhoneNumber(
            phoneNumber,// Phone number to verify
            60,// Timeout duration
            TimeUnit.SECONDS,// Unit of timeout
            this,// Activity (for callback binding)
            mCallbacks);        // OnVerificationStateChangedCallbacks

}



private void verifyPhoneNumberWithCode(String verificationId,String code) {

    PhoneAuthCredential credential = PhoneAuthProvider.getCredential(verificationId,code);


     signInWithPhoneAuthCredential(credential); // this function is creating user account,if not present. But We Don't want this


}

如果用户帐户不存在,以下功能将创建用户帐户,但我不想创建帐户,我只想验证用户输入的代码.有没有可用的回叫方法？

private void signInWithPhoneAuthCredential(final PhoneAuthCredential credential) {
    mAuth.signInWithCredential(credential)
            .addOnCompleteListener(this,new OnCompleteListenerFailed ",Toast.LENGTH_SHORT).show();

                        verifyPhoneNumberWithCode(mVerificationId,editText.getText().toString().trim());

                    }
                }
            });
}
