am missing here? grateful help. thanks!

starting 3.0 (i think) system throws exception if attempt use network on main (ui) thread. chose make system encourage developers not put long running tasks (such network operations) on main thread.

in order fix problem need move network operations(e.g. calls postmessage()) background thread. there few approaches. check out asynctask or using handler / thread. many examples can found online if search "android create background threads"

also this tutorial made lars vogel awesome learning stuff.
