#如果需要使用网络请求及上传文件 请看OKHttpUtils
一个下载Android框架，网络连接用了okhttp，数据库方面用GreenDao，
性能相对用原生的有所提升且支持数据库的一对一、一对多等多表关联，
支持断点下载、加载下载的任务并可给同一个任务设置多个监听，
省去只能设置一个监听要添加一个广播来解决多个页面同时监听同一个下载线程的烦恼，
具备了基本功能，暂时想不出需要添加什么功能，请有需求的提出来，我加上去，

使用方法：
downloadManager = DownloadManager.getInstance(this);
DownloadTask task = new DownloadTask();
String id = MD5.MD5(url);
task.setId(id);
task.setSaveDirPath(getExternalCacheDir().getPath() + "/");
task.setFileName(id+".jpg");
task.setUrl(url);
downloadManager.addDownloadTask(task);
添加监听
downloadManager.addDownloadListener(task,listener);
加载数据库存在的下载任务
downloadManager.loadAllDownloadTaskFromDB();
If you need to request and upload files using the network; See OKHttpUtils
Relative performance has improved with native support and one database, and many-to-many association table,
support breakpoint download, load and download tasks set to the same task with multiple listeners,
Eliminating the need to add only a listener to a broadcast address multiple pages at the same time listen to the same download thread troubles,
With the basic functions, temporarily can not think of what you need to add functionality, there is a demand put forward, I add the phrase,
dzc_ze@foxmail.com needs please send me by mail
##How to use：
downloadManager = DownloadManager.getInstance(this);

task.setFileName(id+".jpg");
task.setUrl(url);
downloadManager.addDownloadTask(task);
// Add a listener
downloadManager.addDownloadListener(task,listener);
// Loads the prevoiusly set tasks from the database

Adding a notification for each task in the task bar
