MainActivity 主要是调用xutils3的各个方法在导包那里找到org.xutils:xutils:3.5.0

   可以获取网络上的数据（get，post）
   可以获取图片

 MyApplication

配置这个import android.app.Application;import org.xutils.x;/** * Created by hua on 2017/8/2. */public class MyApplication extends Application {    @Override    public void onCreate() {        super.onCreate();        x.Ext.init(this);    }}
