Android Firebase手机身份验证INVALID_APP_CREDENTIAL

Question

我已经按照所有步骤为Firebase配置电话身份验证，但是仍然无法从Firebase获取OTP。

将Play商店帐户链接到Firebase进行电话身份验证是否为必填项？

请帮忙 ！！！！！

Answer 1

1. 在Firebase身份验证登录方法中启用电话身份验证。

2. 将此代码粘贴到onCreate方法中。

     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; // ... } }; 

我关闭了自动验证。 用户始终必须输入密码。

3. 发送代码给用户

    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 

4. 从用户那里获取代码并将其发送以进行验证

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

5. 此方法为结果方法

    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] } } }); } 

所有代码均取自Firebase文档。
