[Soot-list] Repackaging and signing apk

[Modhi Alsobiehy]

Thanks Steven!


I did not get how that would work!! the apk is already jimplified and modified!

I followed instrumenting Android  tutorial in which:

I used soot options to get the jimple files from apk source;

modified the jimple files;

used soot options to get dex file from jimple source;


now I have the modified classes.dex - found in sootoutput folder - and other “original” files /folders form the unpacked  apk - unpacked with 7z-.

in the tutorial, it is indicated that I should reassemble the apk, does that mean exchange the old classes.dex with the new dex file in the old apk and repack?? if so, how I should sign it?

if not, then what are the right steps to get the instrumented apk ready for installation?


Thank you!

Hi,

You should not need to manually repackage the APK file by hand at all. 
Make sure the following Soot options are set:

-src-prec apk
-output-format dex
-process-dir <path-to-your-apk>
-android-jars <path-to-your-sdk-platforms-dir>

Afterwards, you need to manually sign the resulting file using 
jarsigner. Please then try to install your signed APK using adb install 
and send us the exact error message in case it fails.

Best regards,
   Steven
