xamarin - Xamarin.Android 链接器问题
问题描述
我有一个以前在发布模式下工作的旧 Xamarin Androd 项目。现在大约 8-9 个月后发生了一些变化,所以我做了它们并检查了在调试模式下工作正常的应用程序。但是当我尝试在发布模式下运行它时,应用程序崩溃了。以下是崩溃发生时来自 android 监视器的错误日志。

经过一番研究,我发现链接器存在一些问题。当前选择仅链接 SDK 程序集。这会使应用程序崩溃。如果我选择无链接,则应用程序工作正常。
我已经尝试过https://docs.microsoft.com/en-us/xamarin/android/deploy-test/linker和https://docs.microsoft.com/en-us/xamarin/cross-platform/部署测试/链接器。那些没有用。
不过,如果有人能在这方面提供帮助,那将是充分的帮助。谢谢。
解决方案
看起来 proguard 正在删除一些与 SQLite 相关的符号。您可以通过访问项目的属性-> Android 选项->跳过链接程序集-> 将值设置为来使 proguard 跳过这些库
