推荐答案

的确是这样，你需要看的 AlarmManager 设置中反复出现的报警。这是更好地为电池寿命的装置上，作为不同于服务不会在后台不断地运行。报警触发广播接收机将执行您的自定义code。

Yes it is, you need to look at the AlarmManager to setup a reoccurring "Alarm". This is better for battery life on the device, as unlike a service it does not run constantly in the background. The Alarm triggers a broadcast receiver which will execute your custom code.

最后一点 - 有用于报警的时机枚举值，包括每日，每日的一半，还有更多，虽然你可以设定一个实际值

As a final note - there are enum values for the timing of the Alarm including daily, half daily and many more although you can just set an actual value.
