android - 不使用 ContentProvider 的自定义 SyncAdapter

Question

我想创建自己的 SyncAdapter，它将我的应用程序中的信息与某个服务器同步。问题是 - 我希望同步本身从我自己的应用程序的上下文中运行，使用我自己与数据库的连接，而无需使用 ContentProvider 访问我的数据库。

那可能吗？

谢谢，

Answer 1

Short answer: No, it's not possible.

Long answer: The Android platform's model for sync is to link a user Account to a ContentProvider through a SyncAdapter. You can't set up the XML tags in AndroidManifest to be read by the Android platform without having set up all three.

Biased answer: You should never write an app with a local DB. ContentProvider is by far the way to go, for the reasons listed here.
