[Steven Arzt]

Hi Jin,

 

The JimpleBody class supports a getThisLocal() method.

 

Best regards,

  Steven

Betreff: [Soot-list] How to get "This" parameter within a java method? (instrument the android apk)

 

Hi All,
   

     I want to insert an invocation in onCreate() method of a android class

        protected void onCreate(Bundle savedInstanceState){

         Context con = getApplicationContext(); // this is the invocation I want to insert


        }

 I do like this:

       Local tmpRef = Jimple.v().newLocal("context", RefType.v("android.content.Context"));
       body.getLocals().add(tmpRef);

       SootMethod invokeContextMethod = Scene.v().getSootClass("android.content.ContextWrapper").getMethod("android.content.Context getApplicationContext()");
       InvokeExpr invokeContext = Jimple.v().newVirtualInvokeExpr(base, invokeContextMethod);
 

 There, "base" should be a Local value which used to invoke the "invokeContextMehtod".  I think it is the "this" paramether within the onCreate method.
 

 But I don't know how to get the "this" parameter and convert it to a Local value in Soot.

Can anybody help me?
