What is a content provider?
A SQLite database is private to the application which creates it. If you want to share data with other applications you can use a content provider (short provider).
A provider allows applications to access data. In most cases this data is stored in an SQlite database.
While a content provider can be used within an application to access data, its is typically used to share data with other application. As application data is by default private, a content provider is a convenient to share you data with other application based on a structured interface.
A content provider must be declared in the AndroidManifest.xml file.

SyncAdapter
SyncResult** by 43matthew - source http://stackoverflow.com/a/17354811
The SyncResult object has a delayUntil field that you can set from your sync adapter which will delay each following sync by the specified number of seconds.
Otherwise, the sync will be rescheduled if
SyncResult.madeSomeProgress() returns true - i.e. some work was successfully accomplished by the sync (corresponding to stats.numDeletes, stats.numInserts > 0, stats.numUpdates > 0) SyncResult.hasSoftError() returns true - i.e. it failed due to an IOException or because SyncResult.syncAlreadyInProgress was true.
The sync adapter can set SyncResult.tooManyRetries = true which will indicate to the SyncManager that the sync is not to rescheduled
PeriodicSync** by Christopher Alexander - source http://digitalassassin.net/2014/03/contentresolver-addperiodicsync-doesnt-work-never-syncs/
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. aka
