But, how come no one asks him why he wants to "get the response data back in the main thread " ? It seems like he believes he needs to pass stuff around so other threads will have access to them (i dont see any UI related calls that would require them to be run on the UI thread). He needs to do more learning on Scopes and Java Threads than info on ASyncTasks.

I think what John was describing does make sense. He had inadvertently created a new response var in an inner scope, thereby effectively masking out his pre-existing instance var of the same name; therefore the response data was being discarded each time the inner scope was exited.
