Question

当我尝试从Firebase Cloud Messages收到通知后打开应用程序时，该应用程序关闭并显示以下错误：

从后台Worker发送的Firebase消息（使用AndroidX.Work）这并非总是会发生，但是我找不到模式。我不在Autofac中注册Realm的实例，并且其他已注册的类在构造函数中不包含实例化Realm实例。

此错误是什么意思，我在做什么错？

环境：

手机Samsung A5 Android 7.0或OnePlus 6T Android9。
Xamarin表格3.6.0.539721
领域4.0.1
Autofac 4.9.2
Xamarin.Firebase.Messaging 60.1142.1

我通过在创建作业和工作程序之前在MainActivity中添加数据库初始化来解决该错误。

如何解决“在使用默认架构创建Realm实例之前，应调用AddDefaultTypes。”
