127.0.0.1 is a Android emulated device's own loopback interface.

In other words, you connect to android emulated device (not to your computer) by using 127.0.0.1.

To get connection to your machine with web-server use 10.0.2.2 or real machine IP address (if you have direct access from web).

Use command ipconfig(Windows)/ifconfig(Linux) to obtain your IP address.
