调用了
AVOSCloud.initialize(this, "appId","appKey");
后台打印
05-13 18:15:02.566: I/===AVOS Cloud===(16344): i->16: statistics library not started since not included
05-13 18:15:02.586: D/===AVOS Cloud===(16344): LogUtil$avlog->d->28: try to fetch host list
05-13 18:15:02.586: I/===AVOS Cloud===(16344): i->16: avpushRouter server didn't switched
获取数据的时候
AVQuery query = new AVQuery("Product");
query.whereEqualTo("YB_barCode", result);

	query.findInBackground(new FindCallback<AVObject>() {
		@Override
		public void done(List<AVObject> list, AVException e) {
			List<AVObject> priorityEqualsZeroTodos = list;

这里的LIst集合是空的?

求大神们指点指点。。。

请将日志打开,将 query 时的日志粘贴出来看下,打开日志的方法:
AVOSCloud.setDebugLogEnabled(true);
