What can I do in the Android emulator to connect it to my localhost web server page at http://localhost or http://127.0.0.1?
I've tried it, but the emulator still takes my request like a Google search for localhost or worse it says that it didn't found the page while my web server is normally running.

If you're using Android Studio to run the emulator, then localhost of your host computer will be mapped to the IP address, 10.0. 2.2 , inside the emulator. If you're using other programs to run the emulator, then you may need to consult the documentation associated with those programs.
On your mobile device's browser (any will work), navigate to http://<Local IP Address>:<port number> . For example, if I was serving on localhost:8080 and my local IP address is 123.45. 67.890, on my mobile device's browser I would navigate to http://123.45.67.890:8080 . The http:// is important, don't leave it off.
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://10.0.2.2:8080".
Case 1: If You Are Using the Emulator So start up your emulator (since it could take a while until it is ready). Start your server at localhost and attach the debugger. Next, change the API endpoints in your Android code to http://10.0.2.2 . This reroutes the requests from your emulator to your computer's localhost.
The localhost refers to the device on which the code is running, in this case the emulator.
If you want to refer to the computer which is running the Android simulator, use the IP address 10.0.2.2 instead.
