How to determine the frequency of SyncAdapter updates on Android?

Question

ContentProvided, defined for synchronization, is dummy (in accordance with this approach ).

Answer 1

If API> 8 (95% of devices) uses ContentResolver.addPeriodicSync()

If API = 7 (5.5% of devices as of March 2102), create a service with a periodic timer ContentResolver.requestSync() and call ContentResolver.requestSync() .

API <6 does not support syncAdapter, so do not worry.
