[Soot-list] Any way to get the body of callback methods (not android default handlers) ?

[Xinxin Jin]

Hi Eric,

Thanks for your reply. I checked all the reachable methods and found no
place invoking onResponse and onErrorResponse.

The statement that invokes StringRequest() method is :

*<com.android.volley.toolbox.StringRequest: void
<init>(int,java.lang.String,com.android.volley.Response$Listener,com.android.volley.Response$ErrorListener)>(
"http://www.google.com <http://www.google.com>", $r7, $r8)*

Here parameters $r7, $r8 correspond to Response.Listener() and
Response.ErrorListener(). Then I continued to track the definition of r7:

*$r7 = new edu.ucsd.mytest.VolleyActivity$1*

But there is no useful statement in edu.ucsd.mytest.VolleyActivity$1 ....

Any ideas ?

Thank you a lot !!
