[Bug] 小组件不显示考试信息

[SolitaryDream-X]

既然能把考试信息列入到日程表里，没理由小组件里列不出来吧，
而且物理实验不也都实现列入日程表里和小组件里了吗

[BenderBlog]

肯定有理由列出来啊，我代码都写着呢，能加载实验信息和考试信息。小部件如果加载某个信息失败了，应该会有报错的。

非常不幸，我没有看到列出来过，我以为没做这个功能

这是和老电表的组件图片，并没有显示考试信息

除了图书馆服务访问错误，其他报错跟您描述的问题毫无关系。他们都是初步访问时候说 ehall 没有连接，等待片刻会自行解决。

请提供版本号：希望不是 1.5.3，这是测试版，我对里数据结构有改动。

[SolitaryDream-X]

版本号为 1.5.4+343，但这个问题我记得1.5.2的时候就有，1.5.3+333同样存在

（图中从上到下依次为1.5.3,1.5.4,1.5.2）

[BenderBlog]

明白，请您降级到 1.5.2 ，如果还有问题再看。小程序代码是单独线程运行的，主程序是不可能看到日志的。所以如果还有问题，那就是我这个版本改小部件代码改炸了。

先别走，降级到 1.5.2 还有错误吗？

有的，上面那个图片里有的，叫PDA的那个就是1.5.2版本的

[BenderBlog]

那只能下个版本修了，我尽快吧……
如果您还想提供更多信息，只能将手机搞进 adb 查看日志了

[hazuki-keatsu]

我怀疑问题出在这里了。

后面两个Controller没有调用更新方法

[hazuki-keatsu]

我觉得应该统一管理小组件更新，在所有相关数据都准备好之后，只调用一次 HomeWidget.updateWidget()，避免异步导致的数据竞争。
