How to Set Recurring AlarmManager to execute code daily

I usually do something more along the lines of:

Intent i = new Intent(this, MyService.class);
PendingIntent pi = PendingIntent.getService(this, 0, i, 0);
AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
am.cancel(pi); // cancel any existing alarms
am.setInexactRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
    SystemClock.elapsedRealtime() + AlarmManager.INTERVAL_DAY,
    AlarmManager.INTERVAL_DAY, pi);

This way, you don't have to worry about re-setting the AlarmManager in your Service.

I usually run this bit of code when my app starts (onResume in my main activity) and in a BroadcastReceiver that is set up to receive BOOT_COMPLETED.

I've written a guide on creating Services and using the AlarmManager, which is based on my own experience and a few tips & tricks I picked off from watching a Google I/O talk. If you're interested, you can read it here.

To answer your question below, all I can do is quote the docs:

public void setInexactRepeating (int type, long triggerAtTime, long interval, PendingIntent operation)

Schedule a repeating alarm that has inexact trigger time requirements; for example, an alarm that repeats every hour, but not necessarily at the top of every hour. These alarms are more power-efficient than the strict recurrences supplied by setRepeating(int, long, long, PendingIntent), since the system can adjust alarms' phase to cause them to fire simultaneously, avoiding waking the device from sleep more than necessary.

Your alarm's first trigger will not be before the requested time, but it might not occur for almost a full interval after that time. In addition, while the overall period of the repeating alarm will be as requested, the time between any two successive firings of the alarm may vary. If your application demands very low jitter, use setRepeating(int, long, long, PendingIntent) instead.

In conclusion, it's not very clear. The docs only say that the alarm "may vary". However, it should be important for you to know that the first trigger might not occur for almost a full interval after that time.

This is working, this will shoot alarm after every 5 seconds

private void setRecurringAlarm() {

        Logger.d(IConstants.DEBUGTAG, "Setting Recurring Alarm");

        Calendar updateTime = Calendar.getInstance();

        updateTime.set(Calendar.SECOND, 5);

        Intent alarmIntent = new Intent(this, AlarmReceiver.class);
        PendingIntent recurringDownload = PendingIntent.getBroadcast(this, 0, alarmIntent, PendingIntent.FLAG_CANCEL_CURRENT);
        AlarmManager alarms = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
        alarms.cancel(recurringDownload);
        alarms.setInexactRepeating(AlarmManager.RTC_WAKEUP, updateTime.getTimeInMillis(), 1000 * 5, recurringDownload); //will run it after every 5 seconds.
    }
