同遇类似问题 sdk 29 在 SupportFragment firstFragment = findFragment(MainContainerFragment.class); 时出现一下错误

一样遇到了这个问题，请问有解决方案吗

https://juejin.im/post/5d406ea0f265da03aa25493d 1.从 Android 9（API 级别 28）开始，系统会限制APP通过反射或JNI调用非Andorid SDK的接口。 2.项目的业务代码可以通过全局搜索检查非SDK接口的使用情况。 3.几乎所有第三方SDK（包括Android support库！！）都有大量通过反射调用非SDK api的情况。通常反射调用时都有try-catch，能够保证应用不崩，但实际功能受影响的程度无法评估。
