提供从 ContentProvider 到标准联系人应用程序的联系人

Question

I've tried to search, but I even can't ask the question in short form.

1. I have SQLite table with id/username/mobile/email.
2. I've created ContentProvider for it.
3. I've created Account through AccountManager(AccountAuthenticator)

All of it working and I can create contacts using my function Sqlite2Contacts . Ie each of SQLite record I provide to ContactsContract with my Account name and type. All contacts visible through standard application and when I remove account all contacts also removed.

All working fine, but... I think I've missed something. I suppose that should be some framework for It.

Ie I bind my ContentProvider to... something using some sort of adapter without manual contacts synchronization.

I need the only answer can I do it or no, not implementation. And if I can... what class/framework/adapter should I use.

Sounds like you're in the wrong direction, you should not be putting your app's contacts in a ContentProvider .

To put app specific contacts in the Contacts DB in Android your app needs two components: Account and SyncAdapter.

The Account allows the user to authenticate (if needed) and to manually remove / sync your app's contacts. The SyncAdapter is called by the system or programatically by your app and syncs RawContacts into the Contacts DB under your app's ACCOUNT_TYPE + ACCOUNT_NAME .

There are two tutorials by Udi you can follow:

• http://blog.udinic.com/2013/04/24/write-your-own-android-authenticator/ (note that the authentication part is optional)
• http://blog.udinic.com/2013/07/24/write-your-own-android-sync-adapter/
