问题描述

我对问题的答案做了很多研究，但没有发现任何东西.我无法在项目中添加.so库.

I researched a lot for an answer of my question, but I didn't find anything. I can't add the .so library in my project.

我将库放在/app/src/main/jniLibs/arm64-v8a中.该项目将完成，但是在执行时会出现以下错误.

I put the library in /app/src/main/jniLibs/arm64-v8a. The project will complile but on execution the following error comes.

谢谢所有答案.

目录结构在这里.arm64-v8a是我的系统的正确文件夹.

Structure of directorys is here. arms64-v8a is the correct folder for my System.

推荐答案

这意味着 libpcsclite.so 在 arms64-v8a 文件夹中找不到.尝试删除.so文件中的多余字符 .1.0.0 (我在图片中看到了此内容)

That means libpcsclite.so not find in arms64-v8a folde. Try to remove your .so file extra character .1.0.0 (I saw this in image)

如果上述解决方案不起作用，请遵循以下内容.

If above solution not work follow the below.

.so文件不仅可以在 arms64-v8a 文件夹中使用.将您的.so文件添加到 armeabi-v7a 目录中.文件夹名称取决于电话硬件(可能是处理器).

The .so file not only work in arms64-v8a folder. Add your .so file in armeabi-v7a directory. The folder name depend on Phone Hardware (May be processor).

.so文件对于特定文件夹(例如 arms64-v8a 或 armeabi-v7a 等)可能会有所不同.通常，最大的设备保护范围 armeabi-v7a .

And .so file May be different for specific folder like arms64-v8a or armeabi-v7a and so on. Generally maximum device cover armeabi-v7a.
