如何在Android Oreo或更高版本上设置闹钟？

Question

I have implemented AlaramManager with background service , It works fine on devices below Oreo. But doesn't work on android Oreo and above as Google stopped background services from working on Oreo and Above.

Is there any source code or any kind resource which will help me to set alarms on android Oreo or above devices?

After searching for a while I found out about JobsIntentService , but couldn't found enough information about it. And I don't know if it is the way to go. Basically, I want to show notifications on particular dates and times.

Thanks in Advance.

Please try bellow method it will work for you.

/**
 * Method for start Alarm on defined minute
 *  @param minutes Minute when you want to start after current time
 * @param context
 */
public static void startAlarm(Context context, int minutes) {
    Logger.print("AlarmReceiver startAlarm  called");
    Intent alarmIntent = new Intent(context, WakefulBroadcastReceiverService.class);
    alarmIntent.setAction("testAPP");
    PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 123451, alarmIntent, PendingIntent.FLAG_CANCEL_CURRENT);
    AlarmManager manager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
    manager.cancel(pendingIntent);
    long alarmPeriodicTime = System.currentTimeMillis() + Utils.getTimeInMilliSec(Constant.TimeType.MINUTE, minutes);
    if (Build.VERSION.SDK_INT >= 23) {
        manager.setExactAndAllowWhileIdle(AlarmManager.RTC_WAKEUP, alarmPeriodicTime, pendingIntent);
    } else if (Build.VERSION.SDK_INT >= 19) {
        manager.setExact(AlarmManager.RTC_WAKEUP, alarmPeriodicTime, pendingIntent);
    } else {
        manager.set(AlarmManager.RTC_WAKEUP, alarmPeriodicTime, pendingIntent);
    }
}
