Android 将数据从服务发送到Roomdatabase的最佳方式
我正在做一个项目，我需要连接到服务器以获取数据并从地图上的数据中绘制标记，每当数据发生变化时，我需要用新的位置更新地图 我使用一个Roomdatabase、Livedata来观察更改，并使用一个连接到服务器并向存储库发送任何更新的服务。但最好的办法是什么呢 提前谢谢 编辑： 这是到目前为止我的代码，我将尝试解释我所设想的工作方式 首先，我有一个网关实体Android 将数据从服务发送到Roomdatabase的最佳方式,android,service,repository,android-room,android-livedata,Android,Service,Repository,Android Room,Android Livedata,我正在做一个项目，我需要连接到服务器以获取数据并从地图上的数据中绘制标记，每当数据发生变化时，我需要用新的位置更新地图 我使用一个Roomdatabase、Livedata来观察更改，并使用一个连接到服务器并向存储库发送任何更新的服务。但最好的办法是什么呢 提前谢谢 编辑： 这是到目前为止我的代码，我将尝试解释我所设想的工作方式 首先，我有一个网关实体 @Entity(tableName = "gateway_table") public class Gateway {
