exception from simulation local variable type mismatch while converting jar to dex

I am trying to apply an aspect on constructor of a class.I have created a jar file of compiled class with aspect. noq i want to convert that jar file to .dex file . But while converting it shows me exception:

F:\sachin\Tools\ADT_Bundle\adt-bundle-windows-x86\sdk\platform-tools>dx --dex --
output=classes.dex Yepme_jar_with_aspect_on_setText.jar

EXCEPTION FROM SIMULATION:
local variable type mismatch: attempt to set or access a value of type int using
 a local variable of type pak.HookYepmeAspect. This is symptomatic of .class tra
nsformation tools that ignore local variable information.

1 error; aborting

This is my aspect code:

public aspect ABC{

        pointcut pkt_findviewbyid(int id):call(View android.app.Activity.findViewById(int)) &&  args(id);

        View around(int id):pkt_findviewbyid(id) && within(com.yepme.*)
        { }
 }

My observation is that whenever i pass int argument to to any pointcut, this error is generated, but i don't know why it behaves like this . so please tell me what can be the solution for this error ...Thanks in advance . .

Solution

  • I know that this reply is too late, but its better than keeping question as unanswered. After a lot of research i found that the around pointcut that takes arguments and if first argument is int then while creating .dex it gives error. So to resolve this i took first argument as target Object and passed it as a target.

    void around(Object target, int arg1,String arg2): call(* *.foo(int,String)) && args(arg1,arg2) && target(target)
{
    <code body>
}

    and it worked for me..
