Syncadapter last update date

问题:

How can obtain the last update date from the sync adapters services (marked with red) ?

回答1:

Interesting. The API would (almost have to be) on android.content.ContentResolver as that's where periodic sync and enable/disable sync is managed. There's no API there to request it.

Are you trying to find this value for your own SyncAdapter or for a third party app?

With your own SyncAdapter, you obviously can just store date() into a single-row sqlite table within your ContentProvider and reference it either from the SyncAdapter or the app.

For a third party app, that information... might not be avaliable?
