貌似是emoji2这个包的相关类被移除了

androidx相关应该跟加载so位置有关，你可以在自定义application里加载so。
还有没必要处理公开的lib,这纯粹给别人逆向提供后门，别人拿没加固前的代码，对比虚拟化后的指令序列，不需要分析vm就能轻易找到映射。

之前issue有androidx相关问题，就是在某次升级改变.so加载位置后报错的，因为加固androidx除了测试兼容性外没什么意义，所以没处理。最简单的解决方法就是自定义application里加载so, 早期版本是这样做，你可以参照早期的代码。

@maoabc 好的，感谢解惑，目前我直接将 androidx 等库exclude掉了，可以正常运行了🙇‍
