Hi Mr.Eric,
I am trying to instrument my android app using soot .I
am trying to assign a local variable to a class object so that i can call
the methods of the class using it. I had noticed that my jimple output the
<init> is not being called
JAVA CODE:
Scene.v().loadClassAndSupport("record.Structure");
SootClass structClass=Scene.v().getSootClass("record.Structure");
SootMethod setGenericParams = structClass.getMethod("boolean
setGenericParams()");
In the chain iterator I am trying to create
an instance of the class. I had created the local as shown below
Local structLocal = Jimple.v().newLocal("$r"
+ locals.size(),structClass.getType());
locals.add(structLocal);
//initializing struct class
Value rValue=Jimple.v().newNewExpr(RefType.v(structClass));
Stmt newAssignStmt = Jimple.v().newAssignStmt(structLocal, rValue);
logBlock.add(newAssignStmt);
units.insertAfter(logBlock, stmt);
JIMPLE REPRESENTATION
$r13 = new record.Logger;
$r12 = new record.Structure;
specialinvoke $r12.<record.Structure: boolean
setGenericParams()>(); //NO INIT BEING CALLED
specialinvoke $r13.<record.Logger: void
log(record.Structure)>($r12);
and I am running into this particular error after writing this piece of
code.
Exception
Exception in thread "main" java.lang.Error: unknown SpecialInvokeExpr (no
call to constructor, super or private method): specialinvoke $r12.
<record.Structure: boolean setGenericParams()>()

Is this the right way of creating an object for a class?? Please help me

adit.
