c# - 创建时无法解析IMvxMainThreadDispatcher类型的参数分派(dispatch)器的参数

我的android应用程序在生产环境中崩溃，我们的崩溃报告工具是xamarinsights，它会转储以下堆栈

我认为在尝试解析和构造mainthreaddispatcher时引发了异常。但我不明白为什么。

    private IMvxMainThreadDispatcher _dispatcher = Mvx.Resolve<IMvxMainThreadDispatcher>();

    private void ShowToastMessage(string message, double duration)
    {
            _dispatcher.RequestMainThreadAction(() =>
            {
                ...
            });
    }

最佳答案

尝试在每次收到推送时初始化mvvmcross系统，因为可以在不同的上下文中执行（卸载应用程序时），但推送通知服务处于活动状态。
MvvmCross initialization
