MainActivity的代码：

package com.myapplication.xutilhttp;
    
    import android.os.Bundle;
    import android.support.v7.app.AppCompatActivity;
    import android.widget.TextView;
    
    import org.xutils.common.Callback;
    import org.xutils.ex.DbException;
    import org.xutils.http.RequestParams;
    import org.xutils.x;
    
    import download.DownloadManager;
    
    /** * 1,导入依赖包 * 2，清单文件注册权限 * 3，在application中初始化xutils * <p/> * 网络访问xutils的用法： * 1，get请求 * 2，post请求 * 3，文件下载，支持断点续传 * 4，文件上传（图片上传，多文件上传）>2G的文件也行 */
    public class MainActivity extends AppCompatActivity { 
        //private String path = "";
        private TextView textView;
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);

            textView = (TextView) findViewById(R.id.txt);
            // myGetString(PathUtils.getList());
           // myPostString(PathUtils.postConmont());
            downloadFile();
        }

            //1，文件下载的地址 2，文件标签 3，文件下载后的存储的地址 4，是否支持断点续传 5，是否支持重命名 6，
