java - 无需使用 Firebase Phone Auth 登录即可进行移动 OTP 验证

Question

我目前正在制作一个 Android 应用程序，我需要在其中验证用户是否使用 OTP 输入了正确的手机号码。用户已经使用他的电子邮件和密码在应用程序中登录。现在我需要验证用户输入的手机号码，而无需使用 firebase phone auth 的 signInWithCrendntial() 方法。我该怎么做？

我的 mCallbacks 是

                @Override
                public void onVerificationCompleted(PhoneAuthCredential credential) {
                    Toast.makeText(getApplicationContext(), "Verification Complete", Toast.LENGTH_SHORT).show();

                    showMessage("Success!!","OTP verified!" + credential);
                    cred = credential;
                    //btn_add_guest.setEnabled(true);

                }

                @Override
                public void onVerificationFailed(FirebaseException e) {
                    Toast.makeText(getApplicationContext(), "Verification Failed", Toast.LENGTH_SHORT).show();
                    Log.i(TAG,"Error is "+e.getMessage());
                }

                @Override
                public void onCodeSent(String verificationId,
                                       PhoneAuthProvider.ForceResendingToken token) {
                    Toast.makeText(getApplicationContext(), "Code Sent", Toast.LENGTH_SHORT).show();
                    mVerificationId = verificationId;
                    mResendToken = token;

                    Log.i(TAG,"VERFICATION ID IS"+mVerificationId);
                    Log.i(TAG,"RESEND TOKEN"+mResendToken);
                    btn_add_guest.setEnabled(false);
                }
            };

我在 button Pressed 上调用此方法，其中 put_otp 是用户输入 OTP 的 textView。

verifyPhoneNumberWithCode(mVerificationId,put_otp.getText().toString());
                    PhoneAuthCredential credential = PhoneAuthProvider.getCredential(mVerificationId, put_otp.getText().toString());
                    Log.i(TAG,credential.getProvider());

private void verifyPhoneNumberWithCode(String verificationId, String code) {

        Log.i(TAG,"RESEND TOKEN IN METHOD IS"+mResendToken);    if(code.equals(mResendToken)&&verificationId.equals(mVerificationId)){
            Toast.makeText(AddGuestActivity.this, "Verification Success", Toast.LENGTH_SHORT).show();

            btn_add_guest.setEnabled(true);
        }
        else
            Toast.makeText(this,"Please provide correct OTP",Toast.LENGTH_SHORT).show();
    }
