android - Scheduled sync adapter runs every 30 seconds -

i use sync adapters in application sync changes server periodically. no matter value put in pollfrequency sync runs every 30 seconds.

i checked on forum , tried changes suggested in replies , pass 'false' synctonetwork parameter when raise notifychange on contentresolver.

on going through training again in detail, stumbled upon difference.

on google developer site -> training section sync adapters training see addperiodicsync -> pollfrequency parameter passed in milliseconds

public class mainactivity extends fragmentactivity { ... // constants // content provider authority public static final string authority = "com.example.android.datasync.provider";  // account public static final string account = "default_account";  // sync interval constants public static final long milliseconds_per_second = 1000l; public static final long seconds_per_minute = 60l; public static final long sync_interval_in_minutes = 60l;  //this line i'm referring public static final long sync_interval = sync_interval_in_minutes *                                           seconds_per_minute *                                          milliseconds_per_second;  // global variables // content resolver accessing provider contentresolver mresolver; ... @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     ...     // content resolver app     mresolver = getcontentresolver();     /*      * turn on periodic syncing      */     contentresolver.addperiodicsync(             account,             authority,             null,             sync_interval);     ...     }     ... } 

on api reference api reference pollfrequency mentioned in seconds. expected unit pollfrequency, milliseconds or seconds? appreciated.

you should add contentresolver.setmastersyncautomatically(true); code. without setsyncautomatically ignored.
