将Android手机与第三方服务器同步

Question

Do you know if the Android SDK provides some classes, interfaces or methods to help developers to create a mechanism in order to synchronize application data between the phone and a third-party server ? Or should we build this mechanism from scratch ?

I've heard about C2DM for Push notification but it is available only from Android 2.2 and my application must support Android 2.1.

Answer 1

Android does synchronization between data stored locally in a content provider and a remote service by means of a SyncAdapter .

Here you have a full example and some docs .

Answer 2

It s been a while but I couldnT find a lot of info on Sync management in Android nowadays either. I wanted to add another link. :

• http://www.c99.org/2010/01/23/writing-an-android-sync-provider-part-1/ . It s also quite old actually(from January, 2010 )
• Then there is another SO post : Android Sync Adapter Resources
