AlarmManager timer
<p>When  useing AlarmManager ,i set many timers,each timer for different broadcast receiver,
 and they will auto merge or not?  </p>

<pre><code>    Intent intent = new Intent(TimeModeService.this,TimeModeReceiver.class);
    intent.setAction("startTimeMode");
    PendingIntent startIntent = PendingIntent.getBroadcast(getApplicationContext(),1000, intent,0);
    can.set(Calendar.HOUR_OF_DAY, startHour);
    can.set(Calendar.MINUTE,startMin);
    alarmmanager.setRepeating(AlarmManager.RTC_WAKEUP, can.getTimeInMillis(), (24 * 60 * 60 * 1000), startIntent);
</code></pre>
