java - Firebase 未正确发送 otp

Question

我正在开发一个具有获取 OTP 功能的应用，并且我使用了 Firebase OTP 功能(使用电话号码在 Android 上通过 Firebase 进行身份验证)，但不幸的是，有时我遇到了像我这样的问题我没有从 firebase 获取 otp，同时也没有给出任何错误。我不知道我犯了什么错误。需要帮助来解决这个问题，我也尝试过一些可以正常工作的示例，但是当我尝试集成到我的项目中时，firebase 没有发送 otp。我想将手机号码发布到 firestore用户当前的国家/地区代码为 ex(+91,+888)。

这是我迄今为止在项目中尝试过的:

package com.example.NewActivity;

import android.content.Intent;
import android.os.Bundle;
import android.support.annotation.NonNull;
import android.support.v7.app.AppCompatActivity;
import android.text.TextUtils;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

import com.example.aayushchaubey.meetdax.R;
import com.example.activity.HomeActivity;
import com.example.activity.PhoneNumberLogin;
import com.google.android.gms.tasks.OnCompleteListener;
import com.google.android.gms.tasks.Task;
import com.google.firebase.FirebaseException;
import com.google.firebase.FirebaseTooManyRequestsException;

public class LoginWithMobileNumber extends AppCompatActivity {

    EditText phoneNo_Edt;

        phoneNo_Edt=(EditText)findViewById(R.id.phoneNoEdt);
        loginBtn=(Button)findViewById(R.id.phoneNoLoginBtn);
        phoneNo_Edt.setSingleLine();
        firebaseAuth= FirebaseAuth.getInstance();

        addOnClickListener();

        mCallbacks = new PhoneAuthProvider.OnVerificationStateChangedCallbacks() {

            @Override
            public void onVerificationCompleted(PhoneAuthCredential credential) {
                // This callback will be invoked in two situations:
                // 1 - Instant verification. In some cases the phone number can be instantly
                //     verified without needing to send or enter a verification code.
                // 2 - Auto-retrieval. On some devices Google Play services can automatically
                //     detect the incoming verification SMS and perform verification without
                //     user action.
                Log.d(TAG, "onVerificationCompleted:" + credential);

                signInWithPhoneAuthCredential(credential);
            }

            @Override

                // This callback is invoked in an invalid request for verification is made,

                // now need to ask the user to enter the code and then construct a credential
                // by combining the code with a verification ID.

我在我的应用程序中使用 Firebase OTP 验证，在花了一周时间解决不同场景后，我了解了以下内容。也许它也会对您的情况有所帮助。

考虑以下场景。

1. 当您调用PhoneAuthProvider.getInstance().verifyPhoneNumber()时，大多数时候Firebase将发送 OTP，我们的代码将收到 onCodeSent打回来。之后，如果设备收到 OTP，sdk 将 调用onVerificationCompleted或onCodeAutoRetrievalTimeOut根据您传入参数的超时值。

2. (也许这可能是您的情况)有时当您调用PhoneAuthProvider.getInstance().verifyPhoneNumber()时，sdk会调用onCodeSent方法，但设备未收到任何 OTP。同时，sdk会自动验证电话号码并调用onVerificationCompleted直接进行，无需发送任何 OTP。

所以你应该考虑上述情况并做出相应的决定。

我仍然不确定这个答案是否能满足您的情况，但它肯定会帮助您更好地理解事情。
