  在通过互联网和firebase文档本身进行研究之后，我在应用程序中使用firebase auth找到了这个两步验证的解决方案 .

  firebaseAuth.getCurrentUser().updatePhoneNumber(credential).addOnCompleteListener(this, new OnCompleteListener<Void>() {
          @Override
          public void onComplete(@NonNull Task<Void> task) {
              if (task.isSuccessful()) {
                  Log.d(TAG, "signInWithCredential:success");
  
                  Snackbar.make(findViewById(android.R.id.content), "Mobile Verified Successfully.",
                          Snackbar.LENGTH_SHORT).show();
  
              } else {
                  Log.w(TAG, "signInWithCredential:failure", task.getException());
                  if (task.getException() instanceof FirebaseAuthInvalidCredentialsException) {
                      //mVerificationField.setError("Invalid code.");
                      Snackbar.make(findViewById(android.R.id.content), "Invalid Code.",
                              Snackbar.LENGTH_SHORT).show();
                  } else {
                      Toast.makeText(context,"signInWithCredential:failure"+task.getException(),
                              Snackbar.LENGTH_LONG).show();
                  }
              }
          }
      });
  

  只需将 PhoneAuthCredential 传递给上述方法即可验证手机是否已分配给您现有的帐户 . 确保其他任何帐户都不使用它 .

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

  now phone auth is available in firebase.Here is Code for Phone Auth using Firebase: 如果有任何问题费免费问我 .

  EditText phoneNum,Code;           //// two edit text one for enter phone number other for enter OTP code
  Button sent_,Verify;                    // sent_ button to request for verification and verify is for to verify code
  private PhoneAuthProvider.ForceResendingToken mResendToken;
  private PhoneAuthProvider.OnVerificationStateChangedCallbacks mCallbacks;
  private FirebaseAuth mAuth;
  private String mVerificationId;
  
  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_phone_number_auth);
  
      phoneNum =(EditText) findViewById(R.id.fn_num);
      Code =(EditText) findViewById(R.id.code);
  
      sent_ =(Button)findViewById(R.id.sent_nu);
      Verify =(Button)findViewById(R.id.verify);
  
      callback_verificvation();                                
  
  
  
  
      mAuth = FirebaseAuth.getInstance();
  
  
  
      sent_.setOnClickListener(new View.OnClickListener() {
          @Override
          public void onClick(View v) {
              String num=phoneNum.getText().toString();
              startPhoneNumberVerification(num);                  // call function for receive OTP 6 digit code
          }
      });
  
  
  
  
  
      Verify.setOnClickListener(new View.OnClickListener() {
          @Override
          public void onClick(View v) {
              String code=Code.getText().toString();
              verifyPhoneNumberWithCode(mVerificationId,code);                 //call function for verify code
  
          }

  抛出此异常是因为您已将电子邮件pw登录和facebook登录连接在一起，使用facebook one中使用的相同电子邮件的Google帐户未关联在一起 . 默认情况下，firebase不允许来自同一电子邮件的多个帐户发生此冲突 .

  要解决此问题，您有两种选择

  1. Link the google account to the facebook and email one's using

  mAuth.getCurrentUser().linkWithCredential(credential);
  

  将新凭据添加到现有登录用户 .

  2. Enable multiple account from same email(not recommended) from the firebase console

  这将为谷歌登录用户创建新的uid，之前的Facebook登录用户将拥有旧的 .
