离子运行android |提供的参数与呼叫目标的任何签名都不匹配

Question

我有course-page.ts和course-data.ts。 课程页面从course-data.ts获取数据。 我希望使用＆＃34;离子运行android＆＃34;来构建我的应用程序但它失败了。 它向我显示了这个错误

这是我的课程 - 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());

      }

    }

当我尝试在网络上运行它时，它运行正常（当我运行＆＃34;离子运行服务＆＃34;）但是当我运行＆＃34;离子运行android＆＃34;它失败了。
