nativeDisclosurer does not work properly

[inttimmy]

Hello, I am a programming novice and am trying to run JuCify
I try to use the following command to analyze the apk file in “benchApps”, and I provided -f and -p parameters

./main.sh -f getter_imei.apk -p ....../Android/sdk/platforms

However, JuCify shows that no new edges or nodes are found

JuCify v0.1 started on Tue Jan 17 13:15:46 CST 2023

So I wondered if there was a problem with the nativedisclosurer.

I ran launch_native_disclosurer.sh alone, it made a lot of ANGR errors

ANGR ERROR:
WARNING | 2023-01-17 12:52:58,416 | angr.project | Address is already hooked, during hook(0x500030, <SimProcedure UnimplementedHook>). Not re-hooking.

launch_native_disclosurer.sh finally displayed Error:
RecursionError: maximum recursion depth exceeded while pickling an object

Did I do something wrong？
I would appreciate it if you could answer my question.

i also meet this the nativeDisclosurer was not worked.

• python version 3.7.7 or 3.8.10
• i can generate the “_result” folder (.dot .result performance .map) successful
• the command is "python ./main.py --out ~/exp/code/JuCify/benchApps/ --cg ~/exp/code/JuCify/benchApps/getter_imei.apk"

the problem is "Has flow through native: No"

could you help me to deal this problem? thanks.

What about your java version?

[Dfault0]

What about your java version?
my java version is:1.8.0.
But i cannot generate the entrypoint file by the nativeDisclosurer.

The problems seems to come from the nativediscloser tool, I would suggest you contact the authors of nativediscloser: https://github.com/gaojun0816/nativediscloser

ok. think you for your reply.

Hi @Dfault0 , I saw you are not using the script given to launch native disclosed right?
and your command does not seem to follow what is in the script:
python3 main.py $FILE --out $DST --cg
You only use the "--out" and "--cg" options, that might be the problem.
Can you confirm?

[Dfault0]

i have used the script
and the command is pythpn ./main.py --out ~/exp/apks/benchApps/ --cg ~/exp/apks/benchApps/delegation_imei.apk

[JordanSamhi]

Did you use this script: https://github.com/JordanSamhi/JuCify/blob/master/scripts/main.sh ?

yes,

[JordanSamhi]

Did you checkout to the following commit: 6897c58 (as explained in the README)?

Also, can you verify you are using Python3.7.7 (as explained in nativediscloser page) ?

i solve this problem by checkout 6897c58 with your help.
i always not checkout this for two reason:

• I think the modified part in the file is originally in pom.xml
• i clone Jucify a few days ago and i thik the modified part is already in the clone file
• I'm not familiar with git.
  Thank you for your help! @JordanSamhi

No problem, glad that it works now!
