How to trigger a background service in android on specific time?

Question

I know how to trigger a background service in android even on specific time. I have used AlarmManager to achieve this, but I want to start that service daily on that time.

Suppose I want to start it on 12pm, but the service should keep going on after that. I have also used the stopitself() method, but that does not work.

Here is my code:

void alram(Context ctx){

    Calendar cal = Calendar.getInstance();
    cal.setTimeInMillis(System.currentTimeMillis());
    cal.set(Calendar.HOUR_OF_DAY, 12);
    cal.set(Calendar.MINUTE, 0);
    cal.set(Calendar.SECOND, 0);
    cal.set(Calendar.AM_PM,Calendar.AM);

    Intent serviceIntent = new Intent(ctx, ServiceClass.class);
    PendingIntent servicePendingIntent =
        PendingIntent.getService(ctx,Service_Apps.SERVICE_ID,serviceIntent,0);

    AlarmManager alarm = (AlarmManager) ctx
        .getSystemService(Context.ALARM_SERVICE);
    alarm.set(AlarmManager.RTC_WAKEUP,cal.getTimeInMillis(),servicePendingIntent);
    alarm.setRepeating(
        AlarmManager.RTC_WAKEUP,
        cal.getTimeInMillis(),
        AlarmManager.INTERVAL_DAY,
        servicePendingIntent
    );
}

@Channa no its not dupplicate , we can start service on specific time , but i am looking for daily basis . — Abhishek, Nov 10 '17 at 11:06
What you can do is plan new .setExact(..) for next day when you execute "old" one. So your Intent will do work+schedule. — Tomas Ivan, Nov 10 '17 at 11:41
