SyncRequest.Builder

SyncRequest.Builder

SyncRequest.Builder ()

build

SyncRequest build ()

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

Returns
SyncRequest	a SyncRequest with the information contained within this builder.

setDisallowMetered

SyncRequest.Builder setDisallowMetered (boolean disallow)

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

Parameters
disallow	boolean: true to allow this transfer on metered networks. Default false.

Returns
SyncRequest.Builder

setExpedited

SyncRequest.Builder setExpedited (boolean expedited)

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().

Parameters
expedited	boolean: whether to run expedited. Default false.

Returns
SyncRequest.Builder

setExtras

SyncRequest.Builder setExtras (Bundle bundle)

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.
   }
 

Only values of the following types may be used in the extras bundle:

• Integer
• Long
• Boolean
• Float
• Double
• String
• Account
• null

If any data is present in the bundle not of this type, build() will throw a runtime exception.

Parameters
bundle	Bundle: extras bundle to set.

Returns
SyncRequest.Builder

setIgnoreBackoff

SyncRequest.Builder setIgnoreBackoff (boolean ignoreBackoff)

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().

Parameters
ignoreBackoff	boolean: ignore back off settings. Default false.

Returns
SyncRequest.Builder

setIgnoreSettings

SyncRequest.Builder setIgnoreSettings (boolean ignoreSettings)

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.

Parameters
ignoreSettings	boolean: true to ignore the sync automatically settings. Default false.

Returns
SyncRequest.Builder

setManual

SyncRequest.Builder setManual (boolean isManual)

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

Parameters
isManual	boolean: User-initiated sync or not. Default false.

Returns
SyncRequest.Builder

setNoRetry

SyncRequest.Builder setNoRetry (boolean noRetry)

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().

Parameters
noRetry	boolean: true to not retry a failed sync. Default false.

Returns
SyncRequest.Builder

setRequiresCharging

SyncRequest.Builder setRequiresCharging (boolean requiresCharging)

Specify whether the sync requires the phone to be plugged in.

Parameters
requiresCharging	boolean: true if sync requires the phone to be plugged in. Default false.

Returns
SyncRequest.Builder

setSyncAdapter

SyncRequest.Builder setSyncAdapter (Account account, 
                String authority)

Specify an authority and account for this transfer.

Parameters
account	Account: Account to sync. Can be null unless this is a periodic sync, for which verification by the ContentResolver will fail. If a sync is performed without an account, the
authority	String: A String identifying the content provider to be synced.

Returns
SyncRequest.Builder

syncOnce

SyncRequest.Builder syncOnce ()

Request that a sync occur immediately. Example

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

Returns
SyncRequest.Builder

syncPeriodic

SyncRequest.Builder syncPeriodic (long pollFrequency, 
                long beforeSeconds)

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);
 

N.B.: Periodic syncs are not allowed to have any of SYNC_EXTRAS_DO_NOT_RETRY, SYNC_EXTRAS_IGNORE_BACKOFF, SYNC_EXTRAS_IGNORE_SETTINGS, SYNC_EXTRAS_INITIALIZE, SYNC_EXTRAS_FORCE, SYNC_EXTRAS_EXPEDITED, SYNC_EXTRAS_MANUAL set to true. If any are supplied then an IllegalArgumentException will be thrown.

Parameters
pollFrequency	long: the amount of time in seconds that you wish to elapse between periodic syncs. A minimum period of 1 hour is enforced.
beforeSeconds	long: the amount of flex time in seconds before pollFrequency that you permit for the sync to take place. Must be less than pollFrequency and greater than MAX(5% of pollFrequency, 5 minutes)

Returns
SyncRequest.Builder
