Firebase 電話號碼身份驗證代碼變空

Question

當我卸載並重新安裝android應用程序時，驗證碼和消息得到完美，但是當我重新啟動應用程序並發送手機號碼進行驗證時，我沒有收到任何消息或驗證碼。 在重新發送按鈕上也是同樣的事情。

我沒有收到任何錯誤消息。

我的代碼是....

   private void sendVerificationCode(String mobile) {
    PhoneAuthProvider.getInstance().verifyPhoneNumber(
             mobile,
            60,
            TimeUnit.SECONDS,
            TaskExecutors.MAIN_THREAD,
            mCallbacks);
   }



  private PhoneAuthProvider.OnVerificationStateChangedCallbacks mCallbacks = 
  new PhoneAuthProvider.OnVerificationStateChangedCallbacks() {
    @Override
    public void onVerificationCompleted(PhoneAuthCredential 
     phoneAuthCredential) {
        String code = phoneAuthCredential.getSmsCode();

        Log.i("sad","codeis========"+code);
        if (code != null) {
            edtphoneemail.setText(code);
            verifyVerificationCode(code);
        }
     }

    @Override
    public void onVerificationFailed(FirebaseException e) {
        //Toast.makeText(VerifyPhoneActivity.this, e.getMessage(), 
         Toast.LENGTH_LONG).show();
        Log.i("a","asdf==="+e);
    }

    @Override
    public void onCodeSent(String s, PhoneAuthProvider.ForceResendingToken 
    forceResendingToken) {
        super.onCodeSent(s, forceResendingToken);
        Log.i("sadf","sdf=====code sucess fiully"+s);
        //storing the verification id that is sent to the user
        mVerificationId = s;
        mResendToken = forceResendingToken;
    }
  };


   private void verifyVerificationCode(String code) {
    //creating the credential
    PhoneAuthCredential credential = 
    PhoneAuthProvider.getCredential(mVerificationId, code);

    Log.i("sdf","mVerificationId===="+code);
    //signing the user
    signInWithPhoneAuthCredential(credential);
  }


 private void signInWithPhoneAuthCredential(PhoneAuthCredential credential) 
 {
    mAuth.signInWithCredential(credential)
            .addOnCompleteListener(this, new OnCompleteListener<AuthResult> 
  () {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
                    if (task.isSuccessful()) {

                      Log.i("sadf","sdf=====code sucess fiully");

                    } else {                    
                    String message = "Somthing is wrong, we will fix it 
                    soon...";

        if (task.getException() instanceof 
                    FirebaseAuthInvalidCredentialsException) {
                            message = "Invalid code entered...";
                        }

                        Snackbar snackbar = 
                        Snackbar.make(findViewById(R.id.parent), message, 
                       Snackbar.LENGTH_LONG);
                        snackbar.setAction("Dismiss", new 
                    View.OnClickListener() {
                            @Override
                            public void onClick(View v) {

                            }
                        });
                        snackbar.show();
                    }
                }
            });
     }

   private void resendVerificationCode(String phoneNumber,
                    PhoneAuthProvider.ForceResendingToken token) {
            PhoneAuthProvider.getInstance().verifyPhoneNumber(
            phoneNumber,        // Phone number to verify
            60,                 // Timeout duration
            TimeUnit.SECONDS,   // Unit of timeout
            this,               // Activity (for callback binding)
            mCallbacks,         // OnVerificationStateChangedCallbacks
            token);             // ForceResendingToken from callbacks
       }

Answer 1

您不會每次都獲得 OTP。 Firebase 會自動檢測手機中的 SIM 卡以及與其關聯的電話號碼。 如果成功，則身份驗證將自動完成，您必須以用戶身份登錄。

Answer 2

我只是將 sim 卡網絡類型 4g 更改為 2g，然后從 firebase 獲取 OTP
