Question: How to modify the code of a targeted function of an app? #294

I want to use Flowdroid to design a program to achieve the following functions: input an apk file of an app, specify function F1 and F2, Function F1 calls function F2. After the program finish, F1 calls F3, and F3 calls F2, the F3 is another function. The output is a new apk, and it works the same as the input except for the relations among F1, F2, and F3. How can I do that?

Hello @heulaoyoutiao,

I think that what you want to achieve has nothing to do with Flowdroid. Maybe what you want is code instrumentation with Soot: https://github.com/soot-oss/soot/wiki/Instrumenting-Android-Apps-with-Soot

Cheers,

Jordan
