How can I get the name of Af if I know Bf?

Answer 1

if you know bf and want to get af, you can generate an exception in afterHookedMethod. I hope you know what that is. If you dont check out this link:

@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
                  (new Exception()).printStackTrace();  
}

from the stack trace you can get the method call.
