Question

所以我正在使用Firebase数据库和Auth，我正在尝试构建Phone Auth，但是由于某种原因，该应用程序崩溃了..不知道为什么。我是刚开始使用Android Studio和Firebase数据库上的第一次编程进行编程的人，不知道为什么应用程序会崩溃，但是在按下激活verifySignInCode（）的按钮后它崩溃了，它确实会发送一封代码为a的电子邮件日志猫错误在这里

这是MainActivity

        if (phone.isEmpty()) {
            etphonenumber.setError("Enter a Phone Number!");
            etphonenumber.requestFocus();

        phone = "+972" + phone;
        Intent intent =  new Intent(this, loginsuccess.class);
            PhoneAuthProvider.getInstance().verifyPhoneNumber(
                phone,        // Phone number to verify

    private void verifySignInCode(){

        }

        @Override

        @Override

    private void signInWithPhoneAuthCredential(PhoneAuthCredential credential) {

                .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                    @Override
                    public void onComplete(@NonNull Task<AuthResult> task) {
                        if (task.isSuccessful()) {

                            registerModule();
                        } else {

                            }
                        }
                    }
                });
    }  
    public void registerModule(){
        Intent intent =  new Intent(this, loginsuccess.class);
        startActivity(intent);
    }

当我按下“ btnAdd”后，崩溃发生了

应用崩溃，因为方法credential无效，phoneAuth无法正常工作。可以通过在try方法上使用catch和signInWithPhoneAuthCredential()来解决此问题。

在代码中它将如下所示：

private void verifyCode(){

        String code = cd.getText().toString(); // this is OTP
        String pH = phone.getText().toString(); // this is phone number
        if(code.equals("") && pH.equals(""))
            Toast.makeText(MainActivity.this,"Nothing to validate", Toast.LENGTH_SHORT).show();
        else {
            try {
                PhoneAuthCredential credential = PhoneAuthProvider.getCredential(otp, code);
                signInWithPhoneAuthCredential(credential);
            }
            catch (Exception e) {
                Log.i("exception",e.toString());
                Toast.makeText(MainActivity.this,"Invalid credentials",Toast.LENGTH_LONG).show();
            }

        }
    }

此外，您应该放置更多catch或if语句，以避免在方法中赋予null值。

只需在调用phoneAuth函数之前定义String代码。

< String code = phoneAuthCredential.getSmsCode();
            assert code != null;
            PhoneAuthCredential credential = PhoneAuthProvider.getCredential(mVerificationId, code);

            signInWithPhoneAuthCredential(credential);>
