[Soot-list] inter-procedural analysis on an android app

[daniela antonova]

Hi,

I would like to write an inter-procedural analysis to analyse Android apps.
At the moment I am trying to create a call graph for an application.
The problem is that the app doesn't have a main method and as a result
I need to define
entry points other than main method. I could not find an example that
does that, so
I would be very grateful for your help.

This is the code I have so far:
public static void main(String[] args) {
		
		List<String> argsList = new ArrayList<String>(Arrays.asList(args));
		argsList.addAll(Arrays.asList(new String[]{
				"-w",
				"-main-class",
				"testers.AddressBook2",//main-class
				"testers.AddressBook2"//argument classes
		}));
		
		PackManager.v().getPack("wjtp").add(new Transform("wjtp.myTrans",
new SceneTransformer() {
			
			@Override
			protected void internalTransform(String phaseName, Map options) {
				CHATransformer.v().transform();
				SootClass a = Scene.v().getSootClass("testers.AddressBook2");
				
				SootMethod src = Scene.v().getMainClass().getMethodByName("onCreate");
				CallGraph cg = Scene.v().getCallGraph();

				Iterator<MethodOrMethodContext> targets = new Targets(cg.edgesOutOf(src));
				while (targets.hasNext()) {
					SootMethod tgt = (SootMethod)targets.next();
					System.out.println(src + " may call " + tgt);
				}
			}

		}));

		args = argsList.toArray(new String[0]);

		soot.Main.main(args);

I got this from the CallGraph example in the Soot source, but I have
not been able to modify it so that I could get rid of the exception:
Exception in thread "main" java.lang.RuntimeException: There is no
main class set!
