I seem to having the same problem as this entry:

The test screen works with a REST post, but not during service invocation under a button.
I just use the standard Android "internal" IP address for localhost: 10.0.2.2. The emulator works just fine using that, to make all my REST calls to a webserver on the same machine. I think I'll try the eclipse source export approach first. Thanks for your help.
