Bundle extras = intent.getExtras();
Messenger mesenger = (Messenger)extras.get(EXTRA_MESSAGER);

3.发送信息

	//创建一条message
        Message msg = Message.obtain();
        msg.what = DownloadItemPresentationModel.UPDATE_UI;
	//存放信息
	Bundle bundle = new Bundle();
        bundle.putSerializable(DownloadItemPresentationModel.EXTRA_DOWNLOADINFO, downloadInfo);
        msg.setData(bundle);
        //发送
