* 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。
