i want to fire some event when system time matches the time stored in my database.I tried out this by using TIME_TICK broadcast receiver.when this receiver receive broadcast, i match my database entries with system time...but problem is that i can register this broadcast receiver from activity only...can't register from manifest file.so, when i close my app or remove it from recent apps list, this broadcast receiver stops working. 我想在系统时间与数据库中存储的时间匹配时触发一些事件。我使用TIME_TICK广播接收器尝试了此操作。当此接收器接收广播时，我将数据库条目与系统时间进行了匹配...但是问题是我可以仅从活动中注册此广播接收器...无法从清单文件中注册。因此，当我关闭我的应用程序或将其从最近的应用程序列表中删除时，此广播接收器将停止工作。 I refer the documentation that says that "TIME_TICK can only register from activity , not from manifest file". 我引用的文档说“ TIME_TICK只能从活动而不是清单文件中注册”。 I also tried to find solution for my problem on stackoverflow and on google but i can't found proper answer. 我也试图为我在stackoverflow和google上的问题找到解决方案，但找不到正确的答案。 so, if you know how to solve it then reply my question and thanks in advance. 因此，如果您知道如何解决，请提前回答我的问题并表示感谢。

That is not possible, as it is incredibly inefficient. 这是不可能的，因为它效率极低。
