ContentResolver.addPeriodicSync doesn’t work – never syncs

By  | March 7, 2014 | Filed under: Software development

Probably you’ve followed Google’s Android sync adaptor training guide up to and are wondering why syncing never happens.

There are two mistakes in the training guide as far as explaining how to make addPeriodicSync work:

  1. You must call ContentResolver.setSyncAutomatically with true as the third (sync) parameter to enable syncing for your adaptor.
  2. The fourth (pollFrequency) parameter of ContentResolver.addPeriodicSync is a number of seconds, as stated here, and not milliseconds, as implied in the training guide. The demo code for addPeriodicSync in the training guide will cause a sync once every thousand hours instead of once an hour.

      I know that the minimum sync interval was one hour on android before API 24 then is it 15 min on android after or equals to API 24
