I am trying get data from a simple api, it works fine in ionic serve(browser) , But when i build the app http call does not work. my Code is
this.http.get("http://example.com/api/routes").subscribe(response => {
this.routes = response["routes"];
for (let x in this.routes) {
let a = this.routes[x].rou_stops;
let b = a.split(",");
for (let y in b) {
this.newCit.push(b[y]);
}
}
});
please help with this issue.

I am Guessing that your are getting this because of android changes its http architecture.
to make it working on Android go to your project root folder.
yourAppFolder > resources > android > xml > network_security_config.xml Change your network security config to blow code.
<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
<base-config cleartextTrafficPermitted="true">
<trust-anchors>
<certificates src="system" />
</trust-anchors>
</base-config>
</network-security-config>

I think you can use Native HTTP plugin for the device use cases:
ionic cordova plugin add cordova-plugin-advanced-http
npm install @ionic-native/http
usage from the doc:
import { HTTP } from '@ionic-native/http/ngx';
constructor(private http: HTTP) {}
...
this.http.get('http://ionic.io', {}, {})
.then(data => {
console.log(data.status);
console.log(data.data); // data received by server
console.log(data.headers);
})
.catch(error => {
console.log(error.status);
console.log(error.error); // error message as string
console.log(error.headers);
});
