Alarm Manager is not working on Android version 9

Question

The app requirement is to trigger an alarm at any specified time and to perform the specified tasks at that particular time. To achieve this i have made use of AlarmManager. But it's not working in Android version 9.

I have used Alarm Manager which is working on Android version 7.0.

I made use of setInexactRepeating() method of AlarmManager.

I have tried to do it using below code :

AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE); am.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);

I expect that the AlarmManager must be triggered at the specified time on Android version 9.

@Thunder workmanager is created to respect dose mode, therefore you can't set work manager at specific time — coroutineDispatcher, Jun 26 '19 at 07:35

This is what i did to fix the issue :

if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT)
   
    am.set(AlarmManager.RTC_WAKEUP, stopTrackingAtMidnight, PendingIntent);

else
   
    am.setExact(AlarmManager.RTC_WAKEUP, stopTrackingAtMidnight, PendingIntent);

setExact() method worked for me !
