将so文件添加到本地android的codenameone代码中？

我正在开发一些新的本机软件包来使用一些特殊的设备，使用的库是（so）文件，如果有人能帮我弄清楚如何将这些文件包括在android构建中，我会很感激，我已经尝试将这些文件添加到本机android文件夹中，但是当尝试从本机调用函数时，显示以下异常：

正如您所看到的，加载so文件和应用程序都没有问题

---

关于，

只需将该文件放在项目的

Android

文件夹

native

中，您就可以在本机源代码中这样使用它。

这些文件位于同一文件夹中，并且[我添加了例外]尝试重命名该文件以将其扩展名从

so

更改为

jar

。由于构建无法扩展ZIP'/tmp/build5780627911063745337xxx/MyApplication/libs/libN20Epp.jar，因此该文件失败。那么

.aar

如何？aar实际上可以工作，在另一个应用程序中，我使用了它，它也可以工作，但有很多（如此）我需要包含的文件，我不知道如何创建一个aar来包装（so）文件
