[Soot-list] Generating Android APK CallFlowGraph

[Steven Arzt]

Hi Lokesh,

 

It seems that you are missing the axml-2.0.jar library on your Java classpath.

 

Best regards,

  Steven

Hi Lokesh,





Open the folder of your project and add the call back file into it.

It's pretty much the same error that you were getting. Though I had checked , there is no duplicate library added. Also there is already AndroidCallbacks.txt in soot-infoflow-android, i haven't understood how to add it into my project.
Any help would be appreciated. Thank You
Regards
Lokesh

Hi all,

I need to traverse the call flow graph of android apps( apk files).

I understand that I must set an entry point so to start, I tried the following code :

 

----------------------------------------------------------------------------------------------------

mport java.io.IOException;

import java.util.Collections;

import org.xmlpull.v1.XmlPullParserException;

import soot.PackManager;

import soot.Scene;

import soot.SootMethod;

import soot.jimple.infoflow.android.SetupApplication;

import soot.options.Options;

public class CFG {

public CFG() {

// TODO Auto-generated constructor stub

}

public static void main(String[] args) {

// TODO Auto-generated method stub

SetupApplication app = new SetupApplication("D:/AndroidADT/adt-bundle-windows-x86_64-20131030/sdk/platforms","D:/APKs/location.apk");

try {

app.calculateSourcesSinksEntrypoints("D:/FlowDroid/SourcesAndSinks.txt");

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (XmlPullParserException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

soot.G.reset();

Options.v().set_src_prec(Options.src_prec_apk);

Options.v().set_process_dir(Collections.singletonList("D:/APKs/location.apk"));

Options.v().set_android_jars("D:/AndroidADT/adt-bundle-windows-x86_64-20131030/sdk/platforms");

Options.v().set_whole_program(true);

Options.v().set_allow_phantom_refs(true);

Options.v().set_output_format(Options.output_format_none);

Options.v().setPhaseOption("cg.spark", "on");

Scene.v().loadNecessaryClasses(); 

SootMethod entryPoint = app.getEntryPointCreator().createDummyMain();

Options.v().set_main_class(entryPoint.getSignature());

Scene.v().setEntryPoints(Collections.singletonList(entryPoint));

System.out.println(entryPoint.getActiveBody());

PackManager.v().runPacks();

System.out.println(Scene.v().getCallGraph().size());

}

}

---------------------------------------------------------------------------------------------------------------------

Unfortunately, I am getting the following error:

Exception in thread "main" java.lang.NoClassDefFoundError: pxb/android/axml/NodeVisitor

Any help or advise on how to do that would be deeply appreciated!

Thanx!!
