android - how to set repeating time in setExact() function of alarm manager -


everyone here saying use setexact api level 19 , higher couldn't find how set repeating time in repeated again @ specified time.

so please tell me how set repeating time in setexact method?

here code

 calendar calendar2,calendar,cal,cal2;         calendar = new gregoriancalendar();         calendar2 = new gregoriancalendar();          calendar2.settimeinmillis(system.currenttimemillis());         calendar.settimeinmillis(system.currenttimemillis());           cal = new gregoriancalendar();         cal2 = new gregoriancalendar();         cal.add(calendar.day_of_year, calendar.get(calendar.day_of_year));         cal.set(calendar.hour_of_day, 10);         cal.set(calendar.minute, 0);         cal.set(calendar.second, calendar.get(calendar.second));         cal.set(calendar.millisecond, calendar.get(calendar.millisecond));         cal.set(calendar.date, calendar.get(calendar.date));         cal.set(calendar.month, calendar.get(calendar.month));             alarmmanager alarmmanager = (alarmmanager)getsystemservice(alarm_service);         intent = new intent(mainactivity.this,start_service_alarm.class);          it.putextra(start_service_alarm.action, start_service_alarm.action);         pendingintent pendingintent = pendingintent.getbroadcast(mainactivity.this, 987654321, it, 0);         if(android.os.build.version.sdk_int<19)         {         alarmmanager.setrepeating(alarmmanager.rtc_wakeup, cal.gettimeinmillis(), alarmmanager.interval_day, pendingintent);         }else         {                alarmmanager.setexact(alarmmanager.rtc_wakeup, cal.gettimeinmillis(), pendingintent);          }             cal2.add(calendar.day_of_year, calendar2.get(calendar.day_of_year));         cal2.set(calendar.hour_of_day, 20);         cal2.set(calendar.minute, 0);         cal2.set(calendar.second, calendar2.get(calendar.second));         cal2.set(calendar.millisecond, calendar2.get(calendar.millisecond));         cal2.set(calendar.date, calendar2.get(calendar.date));         cal2.set(calendar.month, calendar2.get(calendar.month));           alarmmanager alarmmanager2 = (alarmmanager)getsystemservice(alarm_service);         intent itintent = new intent(mainactivity.this,stop_service_alarm.class);          itintent.putextra("action_stop", stop_service_alarm.action_stop);         pendingintent pendingintent2 = pendingintent.getbroadcast(mainactivity.this, 123456789, itintent, 0);         if(android.os.build.version.sdk_int<19)         {         alarmmanager2.setrepeating(alarmmanager.rtc_wakeup, cal2.gettimeinmillis(), alarmmanager.interval_day, pendingintent2);         }else          {             alarmmanager2.setexact(alarmmanager.rtc_wakeup, cal2.gettimeinmillis(), pendingintent2);         }

unfortunately, scheduled times repeating inexact , read inexact full interval!

if targetsdkversion 19 or higher, yes.

what can instead set exact repeating alarm?

use setexact() control initial delay. then, part of work processing event, use setexact() control @ next desired time. iow, "repeating" part yourself.

yes, irritating.

it intentionally irritating, steer developers not use exact repeating alarms, worse battery inexact brethren. if user perceive inexact behavior , not appreciate it, feel free use setexact() make alarms occur when user wants. however, if user not perceive inexact behavior, please use inexact alarms, user may notice battery impact of exact alarms.

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
