MvvmCross Xamarin Android 在初始屏幕上挂起并带有链接

Posted 2023-03-06

【中文标题】MvvmCross Xamarin Android 在初始屏幕上挂起并带有链接

【英文标题】：MvvmCross Xamarin Android Hangs on Splash Screen with linking

【发布时间】：2018-09-12 08:04:20

【问题描述】：

我正在将 MvvmCross 6.1.2 与 Xamarin android 一起使用。通过链接“sdk 和用户程序集”，我的应用程序挂在启动画面中。与其他链接问题不同，日志中没有错误。不知道如何解决它。

init进程的正常流程：Setup.InitializeFirstChance -> App.Initialize -> Setup.InitializeLastChance

到目前为止，我可以确定的是 App.Initialize 和 Setup.InitializeLastChance 之间出现了问题。通过链接，应用可以运行到 App.Initialize 结束，但永远不会到达 Setup.InitializeLastChance。

我在下面附上了 2 个日志。从 App.Initialize 末尾记录的两个日志。第一个是链接直到应用程序挂起。第二个是在 Setup.InitializeLastChange 开始之前没有链接。

通过链接记录

【问题讨论】：

您是否有 LinkerPleaseInclude 文件或提示哪些 MvvmCross 部分不涉及链接的内容？

是的，我做到了。我有 Mvx 的标准 LinkerPleaseInclude，对我自己的代码进行了一些更改。

【参考方案1】：

这种情况很烦人，也很难诊断……

首先，我建议使用linker.config。您可以更好地控制不应与它关联的内容 - 它也很容易设置。

准备好linker.config 文件后，我建议您尝试我用于我的一个应用程序的设置：

<?xml version="1.0" encoding="utf-8"?>
<linker>   
    <assembly fullname="MvvmCross">
        <type fullname="MvvmCross.IoC.MvxPropertyInjector"/>
        <namespace fullname="MvvmCross.ViewModels" />
    </assembly>
    <assembly fullname="MvvmCross.Forms">
        <type fullname="MvvmCross.Forms.Platforms.Android.Views.MvxFormsAppCompatActivity"/>
    </assembly>
    <assembly fullname="MvvmCross.Droid.Support.V7.AppCompat">
        <type fullname="MvxAppCompatActivity"/>
    </assembly>
</linker>

我的linker.config 文件中列出了更多程序集，但我不确定这些程序集在您的情况下有多相关。请尝试将上述内容添加到您的 linker.config 文件中，并检查您是否仍然遇到问题。

如果您的应用仍然死机，那么我倾向于在链接器文件中逐字列出您的所有程序集（项目引用），如下所示：

<assembly fullname="<Assembly_Name>">
    <type fullname="*"/>
</assembly>
<assembly fullname="<Assembly_2_Name>">
    <type fullname="*"/>
</assembly>

我这样做是因为即使您可能认为是 MvvmCross 的东西导致了问题，它也可能是完全不同的库/程序集。所有程序集的这个列表基本上会指示链接器在这些程序集中保留每个Type（不会删除任何东西！）。该应用程序应该与这些一起运行得很好。一旦完成，您就开始从列表中删除程序集。您可以一个一个地完成它或将其分成两半并删除前半部分或后半部分 - 基本上开始消除组件。执行此操作时，您可能希望删除 bin 和 obj，并删除每个程序集 - 只是为了更加确定正在重新生成 dll。

你成功了。它是国际奥委会。包含它后，初始化很顺利。非常感谢。
