推荐答案

在preSS 清除数据从Android应用程序管理器它应该删除有关的一切这被留给应用程序，如preferences，数据库，高速缓存等的仅仅是应用程序，所以当你重新启动它的行为就好像它是刚刚安装。

When you press Clear Data from the Android application manager its supposed to remove everything related to the app such as preferences, databases, caches etc the only thing that gets left is the app so when you re-launch it behaves as if it was just installed.

如果你想允许用户清除数据，但保留数据库那么就应该在删除共享preferences，但并没有对数据库的任何菜单选项。

If you want to allow the user to clear the data but keep the database then there should be an option in the menu that removes the shared preferences but doesn't do anything with the database.

希望这有助于。
