How do I set scope for functions provided by boot-framework.dex?

[oncebeloved]

ENG:
Boot-framework. dex provides a function AXX, which calls another function BXX provided by boot-framework.dex. That is, how do I set the scope of a function that is only called inside boot-framework.dex? (Given that setting android doesn't work, it seems to belong to the BootClassloader) Asking for help? Thank you in advance!
Call link Android -- > Boot-framework.AXX --> Boot-framework.BXX, I require Hook Boot- framework.BXX

CHN:
有这样一个函数AXX，它是 boot-framework.dex提供的，这个函数又调用了 boot-framework.dex提供的另一个函数BXX，我要Hook BXX 请问作用范围要如何设置？也就是说对于一个只在boot-framework.dex 内部调用的函数，作用范围我要如何设置呢？ （已知设置android不起作用，它好像应该属于BootClassloader）请求帮助？先感谢之！
调用链路是 android --> Boot-framework.AXX -->Boot-framework.BXX ，我要求Hook Boot-framework.BXX
