}

that's my course-data.ts

    import { Injectable } from '@angular/core';
import { Http } from '@angular/http';
import 'rxjs/add/operator/map';

/*
  Generated class for the CoursesData provider.

  See https://angular.io/docs/ts/latest/guide/dependency-injection.html
  for more info on providers and Angular 2 DI.
*/
@Injectable()
export class CoursesData {
  public data: any = null;

  constructor(public http: Http) {
    console.log('Hello CoursesData Provider');
  }

      LoadData(data:any){
            let link = "http://adirzoari.16mb.com/selectCourses.php";
            return this.http.post(link,data)
                .map(res => res.json());

      }

    }

when i try to run this in web it's works fine(when i run "ionic run serve") but when i run "ionic run android" it failed.
