I have the widget property in my application. I show the data from the location on the widget but do not show the current data on the layout after 3 4 hours. I can add it to the homepage without problems, but it stops after 3 or 4 hours. Also, after I turn the phone off and on, the widget layout looks empty. How do I feed a widget with a service?
Just make logic of updating appwidget in IntentService (you can schedule it with AlarmManager or JobScheduler) and in appwidget-provider set android:updatePeriodMillis="0". To update app widget from service:
AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context);
RemoteViews views = makeRemoteViewForWidget();
appWidgetManager.updateAppWidget(widgetId, views); //update only one widget
//Or update all widgets
for (int widgetId : ids) {
appWidgetManager.updateAppWidget(widgetId, views);
}
