I tried to run my retrofit library using example to store data into local server and run from emulator then its works fine but when i run from my mobile then give some error. my question is that how do i run this from my mobile and which kind of ip address i use ?

public static final String ROOT_URL = "http://10.0.2.2:8080"; and also giving error from, public static final String ROOT_URL = "http://127.0.0.1:8080";

with emulator it works but not from any mobile, mobile is supportable and its api level is kitkat and more.

After waste my hours, I find this code 

android:usesCleartextTraffic="true"

add this code to your Manifest.xml between application tags.

You use your computer IP address on real device for example your computer has Ip address of 192.168.0.101:8080 use that url in your root url.

it works on emulator because your emulator is running inside the same computer and 127.0.0.1:8080 is your localhost.

please make sure your computer and your device have same Network i.e same wifi router.
