如何使用 Android 中的自定义同步适配器删除联系人？
我编写了一个使用自定义联系人同步适配器的应用程序，它非常适合同步/添加/编辑联系人。但是，我不知道如何在本地设备上删除联系人时通知我的应用程序（或同步适配器服务）。现在的场景如下：
- 用户使用本机通讯录应用程序删除联系人
- 该联系人被标记为删除并从我的自定义同步适配器中删除（它不再显示在通讯录应用程序中）
- 在下次同步期间，我的同步适配器可以看到该联系人已标记为删除，但没有时间戳来知道何时完成此操作
我希望当用户在步骤 1 中删除联系人时通知我的应用程序，然后立即处理该删除。这怎么能做到呢？
谢谢。
I wrote an app that uses a custom sync adapter for contacts, and it works perfectly for synching / adding / editing contacts. However, I can't figure out how t get my app (or the sync adapter service) to be notified when a contact was deleted on the local device. Here is the scenario now:
- A user deletes the contact using the native Contacts app
- That contact gets marked for deletion and removed from my custom sync adapter (it no longer shows up in the Contacts app)
- During the next sync, my sync adapter can see that the contact was marked for deletion, but there is no timestamp to know when this was done
I would like to have my app notified when the user deletes the contact in Step 1, and then immediately process that deletion. How can this be done?
Thanks.
