Android AutoSync Run interval?

Question

Does anyone know that when you have autosync enabled, how frequently are the google accounts synced for various apps? I know its almost instantaneous for Gmail but what about other things? e.g. if I have a Picasa app that uses SyncAdapter to sync local photos with online, how frequently the onPerformSync method will be called?

Also, can this interval be overridden?

Answer 1

AutoSync will be triggered on change in DataSources.

Eg. If you have a Contacts SyncAdapter which is configured for automatic sync then onPerformSync will be called when there is a change in Contacts after a delay of 30s.
