android - AppWidgetProvider onEnabled() -- is widget list known at that point? -

-

i use alarmmanager set repeating alarm each widget updating purposes. it's working well, on devices.

in order re-establish alarms after reboot, relying on onenabled() method, since called once group of app widgets. , in that, have following:

alarmmanager alarmmanager = (alarmmanager) context.getsystemservice(context.alarm_service); appwidgetmanager appwidgetmanager = appwidgetmanager.getinstance(context); int appwidgetids[] = appwidgetmanager.getappwidgetids(new componentname(context, myappwidgetprovider.class)); (int appwidgetid : appwidgetids) {     // call function set repeating alarm widget (including doing widget update now)...     updateappwidgetalarm(context, appwidgetid, appwidgetmanager, alarmmanager); }

whilst seems work in cases, appears devices onenabled() method not doing @ all. know being called, logging put in, nothing happening.

i suspect maybe appwidgetids array empty, because @ time after reboot list has not yet been populated. put in more logging see if correct.

am using onenabled() not intended? should appwidgetids array have meaningful content @ point in app widgets' lifecycle?

i have tried delaying above stuff short time wrapping inside handler.postdelayed(), uncertain results.
