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

[Bodden, Eric]

Hi Xinxin.

I think the problem is that the bytecode's structure differs from the source code's. Although in the source the two anonymous subclasses of Listener resp. ErrorListener are lexically contained in the constructor call, they are not in the bytecode. Please inspect the call to StringRequest.<init>. You should see references the second and third parameter both being initialized with instances of classes such as Response.Listener$1. You have to inspect the bodies of the onResponse methods in those classes.

Hope that helps,
Eric
