Xamarin Android：应用程序崩溃（缺少 libmonosgen-2.0.so）

Question

Xamarin Studio 5.10.3（构建版本27）

设备：小米4c（Android 5.1）

我有一个基本的Android应用程序模板，我正在尝试调试此应用程序。但是它崩溃了...

已安装的包：

Mono.Android.DebugRuntime
Mono.Android.Platform.ApiLevel_19

我尝试过：

adb uninstall Mono.Android.DebugRuntime

然后使用集成开发环境(IDE)或以下命令安装应用程序:

MSBuild /t:Install YourProject.csproj

但是没有成功。

这里有一份logcat：

你的 armeabi 文件夹中使用了 libmonosgen-2.0.so 吗？ - Saveen

我只有一个符号链接到 /data/app-libs/（空文件夹）？我能否编译一个发布版本并将 libmonosgen 从中移动到 /data/app-libs？然后像往常一样进行调试？或者调试情况下会有所不同？ - user64675

我建议通过 adb uninstall <package name>（应用程序，运行时）删除所有内容。然后，您应该清理项目并删除 obj/bin 文件夹。最后，使用 IDE 部署您的调试构建，并确保相应的应用程序在 adb logcat 中搜索到 libmonosgen-2.0 库。 - Jon Douglas

不行，它不起作用。附上一个新的Logcat。 - user64675

@user64675，你找到解决方案了吗？ - xtremebytes

尝试在您的.csproj文件中将属性<AndroidUseSharedRuntime>设置为False。 - DmitryArc

Answer 1

我的解决方法是，在.csproj文件的属性窗口中的Android选项部分中取消勾选"使用共享运行时"。

我猜测这个错误发生在之前安装过其他Xamarin调试应用程序的设备上。如果是这种情况，并且选择了"使用共享运行时"，那么已经在设备上安装的Xamarin运行时版本可能与应用程序所需的版本不兼容。

我遇到了同样的问题，只不过我的应用程序在一个手机上可以正常工作，但在另一个手机上启动后会崩溃。可以正常工作的手机是一个干净的设备，没有其他Xamarin调试应用程序，因此第一次必须安装正确的运行时。而出现崩溃的设备则安装有其他旧版应用程序。

希望这可以帮助到您。

Answer 2

我知道这是一个比较旧的问题，但我在更新Android 9到10时刚遇到了它。我必须将Android包格式从"apk"更改为"bundle"。
