[Soot-list] Get Callsites of each method from callgraph

[Steven Arzt]

Hi Stefan,

 

Sorry for the late reply. To find the component in which a certain method is
called, you need to use the mapping that we have inside the
AndroidEntryPointCreator. We collect all the different components and the
signatures of the methods that get called inside these classes. It's called
"callbackFunctions". Maybe you need to patch the entry point creator
slightly to make this map publicly available, but this should not be too
hard.

 

Best regards,

  Steven

Betreff: [Soot-list] Get Callsites of each method from callgraph

 

Hello,

 

I'm trying to visualize something like a call graph but with grouped methods
for each component. For example instead of having a normal call graph like



 

I want to know in which component each method is called like :

 



 

But I don't know how to get the information, where a method is called. First
I tried using the call graph, traversing it by recursively looking for the
outgoing edges of each node. But it seems that for each node I can only get
the information in which class it is declared, its name, etc. but not the
call sites( where the methods are called for example "method_2 called in
Activity1: onClick()" )

 

Then, instead of using the call graph, I examined the active body of the
entry method (dummyMainMethod) and started looking for all invoke
expressions in there. Then I wanted to use each SootMethod from
InvokeExpr.getMethod() and examine the body of these methods (code below),
but unfortunately it turns out, that there is no active body for these
methods. Can anyone give me an advice how I can achieve my goal?

 

Regards, 

Stefan

 

private static void checkMethod(SootMethod m)

       {

             // don't know if used correctly

             Scene.v().forceResolve(m.getDeclaringClass().getName(),
SootClass.BODIES);

 

             try{

                    if(m.hasActiveBody()){

 

                           Body b = m.getActiveBody();

             

                           for(Unit u : b.getUnits()) {

                                  

                                  Stmt s = (Stmt)u;

                                  if(s.containsInvokeExpr()) {

                                        

                                        InvokeExpr expr = s.getInvokeExpr();

                                        

                                        System.out.println("Found invoke
expression " + expr);

                                        checkMethod(expr.getMethod());

                                  }

                          }

                    } else { System.out.println("Method " + m + " has no
active body");}

             } finally{}

       }
