Accessing localhost:port from Android emulator

Question

I'm running a web service on my local machine that runs at localhost:54722.

I want to call the service from an app running in the Android emulator.

I read that using 10.0.2.2 in the app would access localhost, but it doesn't seem to work with the port number as well. It says HttpResponseException: Bad Request.

Answer 1

You can access your host machine with the IP address "10.0.2.2".

This has been designed in this way by the Android team. So your webserver can perfectly run at localhost and from your Android app you can access it via "http://10.0.2.2:<hostport>".

If your emulator must access the internet through a proxy server, you can configure a custom HTTP proxy from the emulator's Extended controls screen. With the emulator open, click More , and then click Settings and Proxy. From here, you can define your own HTTP proxy settings.
