使用Android.mk将Crypto ++集成到Android中吗？

我想在我的Android应用程序中集成cryptopp模块。我尝试过但没有成功，也找不到任何简单的Android文档或示例。

## TODO - We use this line below in the .mk file:
##            LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/..
## The open question is, should we be exporting the path as:

您要查找的文档位于Crypto++ wiki和Android Setup (Command Line)的Android.mk (Command Line)上。第一篇Wiki文章介绍了如何设置Android构建机器。或许更正确地说，Crypto ++如何设置Android构建机器进行测试。 Wiki的第二篇文章告诉您如何使用Android.mk和Application.mk进行构建，前提是您拥有一台Android构建机器。

当我使用Wiki文章执行构建时，我看到：

如果有足够的时间和磁盘空间，ndk-build将构建所有Android架构。

我不知道如何使用Kotlin或Maven等其他构建系统。我不使用它们，所以如果您的问题出在那儿，我将无法为您提供帮助。

我认为您需要说明遇到的错误，以便人们知道如何为您提供帮助。

注意 ：cryptopp-android以前缺少Crypto ++版本之后的标签。我们今晚已修复该问题，但仅返回到Crypto ++ 7.0。您应确保下载与您使用的Crypto ++版本相对应的cryptopp-android release。它们使用相同的标签，例如CRYPTOPP_7_0_0，CRYPTOPP_8_0_0和CRYPTOPP_8_1_0。硕士应在这两个项目上大致跟随硕士。
