如何从动态共享库Android项目中引用预建的.so库

编程问答 2022-06-10

问题描述

我有一个Android的Xamarin Forms项目（称为MyApp），该项目引用了MyLib项目（动态共享库（Android）Visual Studio项目类型）。在尝试将MyLib项目使用.so库（称为libext.so）之前，一切工作正常。当我启动MyApp时，发生以下日志崩溃：

10-07 13:35:41.833 D/Mono    (27830): DllImport error loading library 'libext': 'dlopen Failed: library "libext" not found'.

**System.DllNotFoundException:** 'Loading...'

我已经使用libext的AndroidNativeLibrary / Abi配置了MyApp。在MyLib项目中，我为链接器/输入/库依赖项设置了“ ext ”，为其他库目录设置了 path / to / lib 。

有人遇到过这个问题吗？感谢您的帮助！
