[Soot-list] Repackaging and signing apk

[Jin Li]

Sorry Modhi,
I thought you have got the .apk file.
>From my knowledge, you don't have to manually change the jimple files.  You
can obtain the unsigned apk file from the original apk file directly.
Just as Steven said, you should first check the Soot options you set.
 And then add a new phase to the jimple-transformation pack "jtp" which
place your instrumentation code directy after the Jimple bodies are
produced.


Best regards
Jin
