[Soot-list] Help regarding Call graph for multiple apk's

[LOKESH JAIN]

Hello All,

This is the code, in this i am calling dotgraph file for making graph. Let
me know if i have to paste that code also. Actually that code i have takenm
form dotgraph of soot only.

import java.io.File;
import java.io.IOException;
import java.util.Collections;
import java.util.HashMap;
import java.util.Iterator;

import org.apache.commons.io.FilenameUtils;
import org.xmlpull.v1.XmlPullParserException;

import soot.MethodOrMethodContext;
import soot.PackManager;
import soot.Scene;
import soot.SootMethod;
import soot.jimple.infoflow.android.SetupApplication;
import soot.jimple.toolkits.callgraph.CallGraph;
import soot.jimple.toolkits.callgraph.Targets;
import soot.options.Options;
public class CFG {
        private static DotGraph dot = new DotGraph("callgraph");
        private static HashMap <String,Boolean> visited = new
HashMap<String,Boolean>();

public CFG() {

}

public static void main(String[] args) {

File dir = new File("/home/lokesh/Desktop/lokesh/sample_applications");
File[] files = dir.listFiles();

for (int i = 0; i < files.length; i++) {
        File f = files[i];
        String source_apk = f.getAbsolutePath();
        soot.G.reset();

SetupApplication app = new
SetupApplication("/home/lokesh/Desktop/android-sdk-linux/platforms/android-19/android.jar",source_apk);


try {

app.calculateSourcesSinksEntrypoints("/home/lokesh/Downloads/soot-infoflow-android-develop/SourcesAndSinks.txt");


} catch (IOException e) {

e.printStackTrace();

} catch (XmlPullParserException e) {

e.printStackTrace();

}


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

Options.v().set_process_dir(Collections.singletonList(source_apk));
Options.v().set_force_android_jar("/home/lokesh/Desktop/android-sdk-linux/platforms/android-19/android.jar");

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 verbose:true", "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());
CallGraph cg = Scene.v().getCallGraph();
//System.out.println("+++++++++++++++++" + cg);
//System.out.println(".................."+entryPoint);
//String label = Scene.v().getCallGraph().listener().toString();
//dot.createSubGraph(label);
visit(cg, entryPoint);
String dest = f.getName();
String fileNameWithOutExt = FilenameUtils.removeExtension(dest);
String destination = "/home/lokesh/Desktop/lokesh/" + fileNameWithOutExt;
dot.plot(destination + dot.DOT_EXTENSION);
//soot.PhaseOptions.getBoolean(Scene.v().getCallGraph().listener(),"dump_cg");
//System.out.println(Scene.v().getCallGraph());

}
}
private static void visit(CallGraph cg, SootMethod k)
{
String identifier = k.getName();

visited.put(k.getSignature(),true);

//System.out.println(dot.drawNode(identifier));
dot.drawNode(identifier);


//iterate over unvisited parents
Iterator<MethodOrMethodContext> ptargets = new Targets(cg.edgesInto(k));


if(ptargets != null){
while(ptargets.hasNext())
{
SootMethod p = (SootMethod) ptargets.next();


if(p == null)
System.out.println("p is null");


if(!visited.containsKey(p.getSignature()))
visit(cg,p);
}
}


//iterate over unvisited children
Iterator<MethodOrMethodContext> ctargets = new Targets(cg.edgesOutOf(k));


if(ctargets != null){
while(ctargets.hasNext())
{
SootMethod c = (SootMethod) ctargets.next();
if(c == null) System.out.println("c is null");
dot.drawEdge(identifier, c.getName());


if(!visited.containsKey(c.getSignature()))
visit(cg,c);
}
}
}
}

Please reply fast as i am stuck here.

Thanks & Regards
