Hi Himanshu, 1) SampleSyncAdapter is still a good source of inspiration. It has some issues and plan to have them fixed in the nearest future.
2) In releases of Android from Eclair through Gingerbread integrated editing of 3rd party contacts is poorly supported. The trick is to insert a data row, "Edit in MyApp", which would take the user to your app and your app would then provide an editor activity. Also, there is no provision in the Contacts UI for creating new contacts in 3rd party accounts. We have fixed those issues in Honeycomb. Now you can specify two activities in your metadata xml file: one for creating new contacts and one for editing existing ones and voilà! - you have seamless integration. Of course, it's a bit too soon to rely on Honeycomb as the dominant version of Android ;-) So for now you will need to either go with the described hack or only allow creation/editing of contacts through your app. 3) Please consider an alternative to using content observers for a sync adapter. There are several reasons: - In order to receive notifications, your process will need to be running at all times. Or it would have to have a broadcast receiver, which is very very costly. - Content observer notifications are not reliable. If your process is not running at the time the change occurs, the notification will never be delivered. A broadcast receiver will solve that problem, but please don't use broadcast receivers for this! - Contacts provider sends out non-discriminated notifications. Whenever anything (e.g. chat presence) changes, all observers are notified whether they have supplied a specific URI or not. What you do want to use is the DIRTY flag and the CALLER_IS_SYNCADAPTER query parameter and let SyncManager invoke your sync adapter. It does some sophisticated scheduling and you want to take advantage of it.
