我正在尝试使用Firebase数据库系统在我的android项目中添加电话身份验证，但是我遇到了“ PhoneAuth Cardential”问题。它显示电话身份验证凭证无法解析，并且无法从外部软件包访问电话身份验证卡。我想使用用户输入的联系电话上发送的代码对用户进行身份验证，以便在身份验证后允许用户登录。

答案 0 :(得分：2)
您应该尝试此行
credential =PhoneAuthProvider.getCredential(verificationID,verificationCode);
代替
credential = new PhoneAuthCredential(verificationID, verificationCode);
