Android Studio localhost API

To access the server from itself, use http://localhost/ or http://127.0.0.1/ . To access the server from a separate computer on the same network, use http://192.168.X.X where X.X is your server’s local IP address. You can find the sever’s local IP address (assuming it’s Linux) by running hostname -I . 127.0.

In our case, localhost means is that our services are running in our local system on a specific port . So instead of localhost we just have to use our system’s IP address.

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.

As you’ve learned, when you use the emulator, localhost ( 127.0. 0.1 ) refers to the device’s own loopback service, not the one on your machine as you may expect . You can use 10.0. 2.2 to access your actual machine, it is an alias set up to help in development.
