I am building a web service, and an android app to utilize it. I am doing both through Eclipse. When I'm running the web server locally, I can connect from my host machine's web browser at http://localhost:8888/. How can I connect to that from my android app running on the emulator on the same machine?

If you are referring your localhost on your system from the Android emulator then you have to use http://10.0.2.2:8888/. Because Android emulator runs inside a Virtual Machine(QEMU) therefore here 127.0.0.1 or localhost will be emulator's own loopback address.
Refer: Emulator Networking

I think you can not connect through localhost. Try to access it though IP address. Because, emulator and Machine making a network.
