Need to acces localhost from my android device

view story

http://stackoverflow.com – I have a php file in the following folder: C:\wamp\www\android_test\fetch_data2 I need to be able to access this file from my application but am unable to get access to it as of now. Here is my Java code and I will highlight where I need to fix. I can access the php file from my computer through localhost/android_data......, but I cannot access it from my phone browser. Also I have no code written in the accompanying xml file and maybe that is why my php file does not show up on the application. Addition notes: I just want my app to display this php file which is connected to a mysql da (HowTos)
