Android Firebase手機身份驗證INVALID_APP_CREDENTIAL

Question

我已按照所有步驟爲Firebase配置手機身份驗證，但仍然無法從Firebase獲取OTP。

是否需要將Play商店帳戶與Firebase關聯以進行電話身份驗證。

請幫忙!!!!!

1. 在Firebase身份驗證登錄方法中啓用電話身份驗證。

2. 在onCreate方法中過去這段代碼。

   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 verificaiton without 
        //  user action. 
        Log.d(TAG, "onVerificationCompleted:" + credential); 
   
        //signInWithPhoneAuthCredential(credential); 
       } 
   
       @Override 
       public void onVerificationFailed(FirebaseException e) { 
        // This callback is invoked in an invalid request for verification is made, 
        // for instance if the the phone number format is not valid. 
        Log.w(TAG, "onVerificationFailed", e); 
   
        Toast.makeText(SignUp.this, e.getMessage(), Toast.LENGTH_LONG).show(); 
   
        if (e instanceof FirebaseAuthInvalidCredentialsException) { 
         // Invalid request 
         // ... 
        } else if (e instanceof FirebaseTooManyRequestsException) { 
         // The SMS quota for the project has been exceeded 
         // ... 
        } 
   
        // Show a message and update the UI 
        // ... 
       } 
   
       @Override 
       public void onCodeSent(String verificationId, 
             PhoneAuthProvider.ForceResendingToken token) { 
        // The SMS verification code has been sent to the provided phone number, we 
        // now need to ask the user to enter the code and then construct a credential 
        // by combining the code with a verification ID. 
        Log.d(TAG, "onCodeSent:" + verificationId); 
   
        // Save verification ID and resending token so we can use them later 
        mVerificationId = verificationId; 
        mResendToken = token; 
   
        // ... 
       } 
   }; 
   

我關掉自動驗證。用戶始終必須輸入代碼。

從用戶

發送碼到用戶

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

取代碼，並將其發送到驗證

String code = mCodeEt.getText().toString(); 
PhoneAuthCredential credential = PhoneAuthProvider.getCredential(mVerificationId, code); 
signInWithPhoneAuthCredential(credential); 

這種方法結果的方法

private void signInWithPhoneAuthCredential(PhoneAuthCredential credential) { 
mAuth.signInWithCredential(credential) 
     .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() { 
      @Override 
      public void onComplete(@NonNull Task<AuthResult> task) { 
       if (task.isSuccessful()) { 
        // Sign in success, update UI with the signed-in user's information 
        Log.d(TAG, "signInWithCredential:success"); 

        FirebaseUser user = task.getResult().getUser(); 
        //Sucess do what u want to do 
        // [START_EXCLUDE] 
        //updateUI(STATE_SIGNIN_SUCCESS, user); 
        // [END_EXCLUDE] 
       } else { 
        // Sign in failed, display a message and update the UI 
        Log.w(TAG, "signInWithCredential:failure", task.getException()); 
        if (task.getException() instanceof FirebaseAuthInvalidCredentialsException) { 
         // The verification code entered was invalid 
         // [START_EXCLUDE silent] 
         mCodeEt.setError("Invalid code."); 
         // [END_EXCLUDE] 
        } 
        // [START_EXCLUDE silent] 
        // Update UI 
        //updateUI(STATE_SIGNIN_FAILED); 
        // [END_EXCLUDE] 
       } 
      } 
     }); 
     } 

所有代碼取自firebase doc ....
