嗨,我希望我的应用程序每天在特定时间运行.为此,我使用下面的代码.但它只运行一次.这里的错误是怎么来实现这个任务的.

AlarmManager alarmMgr0 = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
Intent intent0 = new Intent(this, ActivityStarter.class);
PendingIntent pendingIntent0 = PendingIntent.getBroadcast(this, 0, intent0, 0);
Calendar timeOff9 = Calendar.getInstance();
timeOff9.set(Calendar.HOUR_OF_DAY, 16);
timeOff9.set(Calendar.MINUTE, 13);
timeOff9.set(Calendar.SECOND, 0);
alarmMgr0.setRepeating(AlarmManager.RTC_WAKEUP, timeOff9.getTimeInMillis(),24*60*60*1000,pendingIntent0);

请帮忙.
