该如何处理？

找之前的issue有相关讨论, 要加固androidx相关，自己改so加载位置到自定义application里。顺便说一句加固开源库没任何意义，还能让人简单找到opcode映射表。这种跟那些隐藏dex的加固有很大的不同，弄清楚基本原理再使用。

有参考的代码可以看看吗？

可以看以前代码，最初就是在自定义application里注入的静态初始化方法里System.loadLibrary("libnmmp.so")。后面更新才在NativeUtils里加载so，目前只是推测原因（两个类互相引用，类加载时导致静态初始化方法还没执行就提前调用本地方法，然后报错找到不到native方法）。简单解决就是忽略一些类，打断这种循环引用，或者前面提到的自定义appliction里加载so
