How can I get the repeat alarm for every day using alarm manager in Android?

I am developing alarm application for that I need to invoke alarm repeatedly for the same time for all days. I am using the code to invoke the alarm,

c = Calendar.getInstance();

    c.set(Calendar.HOUR_OF_DAY,10);
    c.set(Calendar.MINUTE, 0);
    c.set(Calendar.SECOND, 0);
    c.set(Calendar.MILLISECOND, 0);

Intent intent = new Intent(HomeActivity.this, MyAlarmService.class);
            PendingIntent pendingIntent = PendingIntent.getService(HomeActivity.this, 123123, intent, 0);
            alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
            alarmManager.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, c.getTimeInMillis(), (24*60*60*1000), pendingIntent);

By using this code I am only invoking present day at 10AM, not for all days. Is there another way to do this?

In your class MyAlarmService, when the alarm is on, reset the alarm. You can even send values for MyAlarmService in the intent when setting the alarm (maybe to stop the alarm)

  1. Update time, and ring the alarm for every 5 minutes:

    Intent intent = new Intent(this, this.getClass());
PendingIntent pendingIntent =
    PendingIntent.getService(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

long currentTimeMillis = System.currentTimeMillis();
long nextUpdateTimeMillis = currentTimeMillis + 5 * DateUtils.MINUTE_IN_MILLIS;
Time nextUpdateTime = new Time();
nextUpdateTime.set(nextUpdateTimeMillis);

AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
   alarmManager.set(AlarmManager.RTC, nextUpdateTimeMillis, pendingIntent);

  2. Set when the alarm works for everyday (for example, 8am-18pm)

    // if not the time to ring, set to the next day
if (nextUpdateTime.hour < 8 || nextUpdateTime.hour >= 18)
{
    nextUpdateTime.hour = 8;
    nextUpdateTime.minute = 0;
    nextUpdateTime.second = 0;
    nextUpdateTimeMillis = nextUpdateTime.toMillis(false) + DateUtils.DAY_IN_MILLIS;
}
else{
    // call your alarm
}
