我想在我的应用程序中实现这个用于otp验证的api，请求用户同意从服务器（firebase）发送的文本消息中读取验证代码，并且我遵循了googleapi指南中的所有指导原则(https://developers.google.com/identity/sms-retriever/user-consent/request). 这是文件
otpverification活动是我想要实现这个功能的地方。当otp从服务器成功发送并且用户从登录活动进入otp验证活动时，应用程序崩溃。
下面是调试屏幕的截图


这是我的logcat截图，应用程序崩溃了

OTP验证活动代码

    private fun parseOneTimeCode(message: String?): Int {
