Call Graph construction

[jsmi.a...@gmail.com]

Hi,

I just came across this tool. Excellent tool.

I am trying to understand how Androguard builds call graph of apps. 

I ran Androguard on more than 700 apps and found that it is able to cover more than 70% of methods in the main tree on an average. I wonder how does it handle abundant callbacks made by Android framework, such as onClick, onLocationChanged, etc.

Hi Jia Smith, 

Could you kindly guide me on how to construct a Static Function Call Graph(SFCG) of an Android App using Androguard. I suppose from your answer that you were able to get the call graph. The reason I need the code to generate SFCG is for my research project that I'm currently working on. 

I tried following this tutorial : 

                                      https://forensics.spreitzenbarth.de/2015/10/05/androguard-a-simple-step-by-step-guide/

and could get all the information except on how to generate SFCG. 

Thanking you in anticipation.

Hi!

You can use the Xrefs generated in the androguard.core.analysis.analysis.Analysis object.
