[Soot-list] Converting .jimple files back into a .dex file and reassembling the apk!

[Modhi Alsobiehy]

Hi Steven,


Thanx a lot for responding!


That what I have been doing but unfortunately if I install the reassembled apk without signing ,installation always fails and I if I try to sign it, jarsigner gives the following error message:

jarsigner: unable to open jar file


I aslo tried to remove the “META-INF” folder before resigning the apk and still no luck!!


any experience or ideas are really appreciated!


Thanx again!

Modhi,,

Hi Modhi,

 

Soot produces a new APK file if the source format is set to APK and the output format is set to DEX. If you write out Jimple files and then re-create the DEX file, you need to manually assemble the APK which should however be simple: Just takethe old APK (which is just a renamed ZIP file) and replace the contained classes.dex file with the newly created one.

 

Best regards,

  Steven

Hi all,


I am trying to automate an instrumentation of an apk but for some reason it is not working as expected!


because of that, I want to do it manually to make sure that the instrumenting statements are correctly placed..


For this to be done, in the ccs2013 tutorial  slide #114 , the steps are:


1• Convert APK to .jimple files (-f jimple)

2• “Instrument” .jimple files manually by editing them in your favorite text editor

3• Convert .jimple files back into a .dex file (-src-prec jimple)

4• Reassemble APK

5• Test the generated APK

6• If it works, automate the instrumentation

steps 1,2, and 3 are done smoothly. I got the classes.dex file, however I did not get how to do step 4! 

I would really appreciate some guidelines explaining how to reassemble an apk starting from classes.dex file!

Thanx,

Modhi,,
