A python script to extract the function call graph from .apk file

I use Androguard to initialize the call graph. If you are interested in Androguard, you can visit its repo.

Installation

download the repo

git clone https://github.com/Gax-c/APKFCG.git

install Androguard

First, make sure you have installed Androguard, if you have installed it, you can skip this slice.

If not, you can visit its repo for installation, or you can install it from this repo.

If you want to install Androguard from this repo, please follow the following steps:

cd androguard
pip install -r requirements.txt
python setup.py install 

Please make sure the version of your networkx is 2.5

The version of this androguard is 3.4.0

usage

The main components are initializeFCG.py、generateFCG.py、main.py

initializeFCG.py is used to initialize the FCG, which uses Androguard to generate the FCG.

generateFCG.pyis used to filter the FCG, you can use the parameter --CLASS, --METHOD, etc. to filter the FCG.

Finally the program will output the number of the nodes left, and three sets internalNode, externalNode, exsistingEdgewill be returned.

You can only use main.py to achieve the functions above.

example

python main.py app-debug.apk --CLASS

run above to get the FCG of app-debug.apk by class.
