How to start service automatically at specific time every day in Android?

Question

我已经在我的应用程序中实现了服务活动，即我想在未先打开应用程序时在应用程序的后台获取数据。但是现在我想在特定或特定的时间启动服务，例如今天我的服务从下午12点，之后每天凌晨12点开始服务，请问该如何做。有人可以帮助我。谢谢。

As the comments state, AlarmManager is the class you're looking for. However it's not a great idea to start a service at an EXACT time, because if your app is popular and you have a million users, they're all going to hit your backend at exactly midday every day...
