Question

我已按照所有步骤为firebase配置phone auth但仍然无法从firebase获取OTP。

是否必须将Play商店帐户链接到firebase for phone auth。

请帮忙!!!!!

在firebase身份验证登录方法中启用手机身份验证。

在onCreate方法中过去了这段代码。

   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;

        // ...
    }
};

我关闭了自动验证功能。用户总是必须输入代码。

将代码发送给用户

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

从用户处获取代码并发送以验证

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

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]
                }
            }
        });
       }
