如果使用创建的ndk lib，有没有不包含.so文件的方法? [英] Is there a way to don't include .so file if I use created ndk lib?

问题描述

我创建了使用NDK ArCore的Android库

I created Android lib that use NDK ArCore

https://developers.google.com/ar/develop/c/enable-arcore

然后我建立了一个lib并得到了.aar文件.然后，我创建了一个新的示例项目，并像一个模块(导入.JAR/.AAR包)一样包含了此.aar文件，并像依赖项一样将其链接了起来，所以一切正常.

Then I built a lib and got .aar file. Then I created new sample project and included this .aar file like a module (import .JAR/.AAR package) and linked it like dependency, so all works fine.

问题是-当我尝试调用使用ArCore的方法时，出现此类错误

Issue is - when I try to call method that use ArCore I am getting such error

为了修复它: 构建我的库之后，在构建目录下有一些自动生成的文件，在其中我找到了arcore-native目录，并且有四个目录

In order to fix it: After I build my lib there are some autogenerated files under build dir, there I found arcore-native dir and there four dirs

我刚刚将此源移动到了main目录下的示例项目中，现在它可以正常工作了

I just moved this source to my sample project under the main dir and now it is completely works

问题是-实现lib时，是否可以在项目中的.so文件中不包含此目录?也许我需要以某种方式直接将它们包括在内?

Question is - is there is a way to don't include this dirs with .so files in project when implementing the lib? Maybe I need to include them directly to lib somehow?

建议.因为每次要求要实现我的lib的用户都会感到有些困难，同时还包含带有.so文件的目录...

P.S. Because it is a little bit hard everytime ask user that want to implement my lib also include a few dirs with .so files...

推荐答案

您可以将 arcore-native 中的.so文件放入您的.aar文件中，它们将随您的lib一起提供

You can put the .so files from arcore-native in your .aar file and they will be delivered with your lib.
