2、可以猜测下载任务名称
3、自动设置下载路径
4、支持断点续传
5、所有监听返回的接口,例如onAdd等,都支持UI操作

使用例子:
DownloadManager downloadManager = new DownloadManager(this);
DownloadTask task = new DownloadTask(this);
task.setUrl("https://github.com/snowdream/android-autoupdate/raw/master/docs/test/android-autoupdater-v0.0.2-release.apk");
downloadManager.add(task, listener); //Add the task
downloadManager.start(task, listener); //Start the task
downloadManager.stop(task, listener); //Stop the task if you exit your APP.
private DownloadListener listener = new DownloadListener() {
    /**
     * The download task has been added to the sqlite.
     * 

* operation of UI allowed. * * @param downloadTask the download task which has been added to the sqlite. */ @Override public void onAdd(DownloadTask downloadTask) { super.onAdd(downloadTask); Log.i("onAdd()"); list.add(downloadTask); Log.i(""+downloadTask); adapter.notifyDataSetChanged(); } /** * The download task has been delete from the sqlite *

* operation of UI allowed. * * @param downloadTask the download task which has been deleted to the sqlite. */ @Override public void onDelete(DownloadTask downloadTask) { super.onDelete(downloadTask); Log.i("onDelete()"); } /** * The download task is stop *

The specified * result is the value returned by doInBackground(Params...).
