SyncRequest.Builder

Performs validation over the request and throws the runtime exception IllegalArgumentException if this validation fails.

Will throw an IllegalArgumentException if called and setIgnoreSettings(boolean) has already been called.

An expedited sync runs immediately and can preempt other non-expedited running syncs. Not valid for periodic sync and will throw an IllegalArgumentException in build().

Developer-provided extras handed back when sync actually occurs. This bundle is copied into the SyncRequest returned by build(). Example:

   String[] syncItems = {"dog", "cat", "frog", "child"};
   SyncRequest.Builder builder =
     new SyncRequest.Builder()
       .setSyncAdapter(dummyAccount, dummyProvider)
       .syncOnce();

   for (String syncData : syncItems) {
     Bundle extras = new Bundle();
     extras.setString("data", syncData);
     builder.setExtras(extras);
     ContentResolver.sync(builder.build()); // Each sync() request creates a unique sync.
   }

Convenience function for setting SYNC_EXTRAS_IGNORE_BACKOFF. Ignoring back-off will force the sync scheduling process to ignore any back-off that was the result of a failed sync, as well as to invalidate any delayUntil value that may have been set by the adapter. Successive failures will not honor this flag. Not valid for periodic sync and will throw an IllegalArgumentException in build().

Convenience function for setting SYNC_EXTRAS_IGNORE_SETTINGS. Not valid for periodic sync and will throw an IllegalArgumentException in build().

Throws IllegalArgumentException if called and setDisallowMetered(boolean) has been set.

Convenience function for setting SYNC_EXTRAS_MANUAL. Not valid for periodic sync and will throw an IllegalArgumentException in build().

Convenience function for setting SYNC_EXTRAS_DO_NOT_RETRY. A one-off sync operation that fails will be retried with exponential back-off unless this is set to false. Not valid for periodic sync and will throw an IllegalArgumentException in build().

Specify an authority and account for this transfer.

Request that a sync occur immediately. Example

     SyncRequest.Builder builder = (new SyncRequest.Builder()).syncOnce();
 

Build a periodic sync. Either this or syncOnce() must be called for this builder. Syncs are identified by target android.provider and by the contents of the extras bundle. You cannot reuse the same builder for one-time syncs after having specified a periodic sync (by calling this function). If you do, an IllegalArgumentException will be thrown.

The bundle for a periodic sync can be queried by applications with the correct permissions using getPeriodicSyncs(Account, String), so no sensitive data should be transferred here. Example usage.

     Request a periodic sync every 5 hours with 20 minutes of flex.
     SyncRequest.Builder builder =
         (new SyncRequest.Builder()).syncPeriodic(5 * HOUR_IN_SECS, 20 * MIN_IN_SECS);

     Schedule a periodic sync every hour at any point in time during that hour.
     SyncRequest.Builder builder =
         (new SyncRequest.Builder()).syncPeriodic(1 * HOUR_IN_SECS, 1 * HOUR_IN_SECS);
