/**

|
* Created by Aria.Lao on 2017/6/6.
|
|
* Aria下载事件被注解的方法中，参数仅能有一个，参数类型为{@link com.arialyy.aria.core.download.DownloadTask}
|
|
* <pre>
|
|
* <code>
|
|
* {@literal @}Download.onPre(DownloadUrl)
|
|
* protected void onPre(DownloadTask task) {
|
|
* mUpdateHandler.obtainMessage(DOWNLOAD_PRE, task.getDownloadEntity().getFileSize()).sendToTarget();
|
|
* }
|
|
* </code>
|
|
* </pre>
|
|
* {@literal @}Download.onPre("http://www.baidu.com")，如果你的注解中增加了url描述，
|
|
* 则表示，所有下载任务中，只有下载地址为"http://www.baidu.com"的任务才能回调该注解的方法。
