和机器人。 启动时升级数据库
原标题:Android. Upgrade database on startup

Im 指Adroid 中的可搜索字典 v2 样本代码。在此示例中,在内容提供者中,当使用升级方法检测到一个新的数据库版本时,数据库将被销毁并重新创建。但这种方法只有在搜索被引用时才开始。现在我更喜欢在应用程序升级后第一次启动应用程序时在上调中引用。所以如果在不同的活动中执行升级方法,我如何在主活动中进行升级工作? 感谢您的帮助

最佳回答

只需在内容中创建更新方法 Provider 正如巴拉克建议的那样 您将只打开并关闭 db, 这将自动触发 Ontograve United Enter Exolver 以主活动方式调用该方法, 并完成 :)
