系统应用程序或应用程序能够在数据库中存储信息。我的问题现在是：例如，Launcher应用程序确实将类似应用程序数量的设置及其在主屏蔽，小部件等的位置存储在数据分区上的数据库中。
这些设置通常只是从数据库中读取，即使有一个新的启动器应用程序替换，具有托盘的不同设置。
我的问题现在： Is there any method(via shell) to trigger an update or re-read of this apps database, so that the new values from the new Launcher replacement are taken into account without just deleting the whole database or messing around with the current database?
System apps or apps in general are capable of storing information within a database. My problem is now: for example the Launcher app does store settings like the amount of apps and their position on the homescreen, widgets etc. into a database on the data partition.
These settings are usually just read from the database again even if there is a new Launcher app replacement with different settings for the homescreen.
My question is now: Is there any method(via shell) to trigger an update or re-read of this apps database, so that the new values from the new Launcher replacement are taken into account without just deleting the whole database or messing around with the current database?
只是为了从安德鲁的评论中归档正确的答案：
然后，只要数据库文件在那里，应用程序将读取它 它需要阅读它。没有必要强制读/更新 外面（嗯，我甚至不确定是否有可能）。它应该是 在应用程序本身内控制。如果我仍然无法掌握，请道歉 这个想法，也许其他读者可能有解决方案。
我对这些数据库是如何处理的。正如安德鲁写的那样：它取决于数据库的实际实现以及如何重新读取。
Just to archive the right answer from Andrew's comment:
Then, as long as the database file is there, the app will read it when it needs to read it. There is no need to force read/update from outside (well, I'm not even sure if it's possible). It should be controlled within the app itself. Apologize if I still couldn't grasp the idea, maybe other readers might have solution for this.
I was confused about how these databases are handled. It is exactly as Andrew wrote: It depends on the actual implementation when and how the database is re-read.
