Android安排闹钟周一至周三 - 周五(Android Schedule Alarm Mon - Wed - Fri)

 我已经阅读了很多关于如何设置警报的教程。 对于我的项目，我遵循Google提供的代码（下载示例按钮@ https://developer.android.com/training/scheduling/alarms.html ）但是每次设置时我的警报都会触发。 这是代码。 
 
alarmMgr = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(context, AlarmReceiver.class);
alarmIntent = PendingIntent.getBroadcast(context, 0, intent, 0);
// Set the alarm to fire at approximately 6:00 p.m., according to the device's
// clock, and to repeat mon, wed, fri.
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
// Set the alarm's trigger time to 2:49 p.m.
calendar.set(Calendar.HOUR_OF_DAY, 14);
calendar.set(Calendar.MINUTE, 49);
calendar.set(Calendar.SECOND, 00);
calendar.set(Calendar.MILLISECOND, 00);
int day = 2;
while(day < 7){
   //2 - monday, 4 - wednesday, 6 friday
   calendar.set(Calendar.DAY_OF_WEEK,day);
   alarmMgr.setInexactRepeating(AlarmManager.RTC_WAKEUP,  
   calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, alarmIntent);
   day += 2;
}
 
 编辑1：昨天我注意到这个闹钟在分钟49，例如14：49,15：59,16：49等每小时都在激活（除了我每次设置）。 

I have read a lot of tutorials about how to set up an alarm. For my project I'm following the code provided by Google (Download the sample button @ https://developer.android.com/training/scheduling/alarms.html) however my alarm fires every time I set it. This is the code.
 
alarmMgr = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(context, AlarmReceiver.class);
alarmIntent = PendingIntent.getBroadcast(context, 0, intent, 0);
// Set the alarm to fire at approximately 6:00 p.m., according to the device's
// clock, and to repeat mon, wed, fri.
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
// Set the alarm's trigger time to 2:49 p.m.
calendar.set(Calendar.HOUR_OF_DAY, 14);
calendar.set(Calendar.MINUTE, 49);
calendar.set(Calendar.SECOND, 00);
calendar.set(Calendar.MILLISECOND, 00);
int day = 2;
while(day < 7){
   //2 - monday, 4 - wednesday, 6 friday
   calendar.set(Calendar.DAY_OF_WEEK,day);
   alarmMgr.setInexactRepeating(AlarmManager.RTC_WAKEUP,  
   calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, alarmIntent);
   day += 2;
}
 
Edit 1: Yesterday I noticed that this alarm is activating (besides every time I set it) every hour at the minute 49, example 14:49, 15:59, 16:49, etc.
