Question

I’m working on a app with a widget which I want to update on a regular basis. I’ve set android:updatePeriodMillis=”3600000″ but my ListView doesn’t update. What is it that I’m missing?

Can you please check if your onUpdate(…) function getting call or not. If onUpdate() is getting called after update period, you need to call notifyAppWidgetViewDataChanged() for ListView’s adapter; in-order to update it.

AppWidgetManager mgr = AppWidgetManager.getInstance(context); 
int[] ids = mgr.getAppWidgetIds(new ComponentName(context, AppWidgetProvider.class));
mgr.notifyAppWidgetViewDataChanged(yourWidgetId, R.id.list_view);
