任务杀死后使用AlarmManager

SilenceReceiver silenceReceiver = new SilenceReceiver();
IntentFilter silenceFilter = new IntentFilter(SilenceReceiver.SILENCE_ALARM);
registerReceiver(silenceReceiver, silenceFilter);

AwakeReceiver awakeReceiver = new AwakeReceiver();
IntentFilter awakeFilter = new IntentFilter(AwakeReceiver.WAKE_ALARM);
registerReceiver(awakeReceiver, awakeFilter);

GregorianCalendar sleepCalendar = new GregorianCalendar();
sleepCalendar.set(Calendar.SECOND, sleepCalendar.get(Calendar.SECOND)+5);
long triggerTime = sleepCalendar.getTimeInMillis();

GregorianCalendar awakeCalendar = new GregorianCalendar();
awakeCalendar.set(Calendar.SECOND, awakeCalendar.get(Calendar.SECOND)+30);
long awakeTime = awakeCalendar.getTimeInMillis();

AlarmManager alarm = (AlarmManager) this.getSystemService(Service.ALARM_SERVICE);
PendingIntent sleepIntent = PendingIntent.getBroadcast(this, 0, new   Intent(SilenceReceiver.SILENCE_ALARM), 0);
alarm.set(AlarmManager.RTC_WAKEUP, triggerTime, sleepIntent);
PendingIntent awakeIntent = PendingIntent.getBroadcast(this, 0, new Intent(AwakeReceiver.WAKE_ALARM), 0);
alarm.set(AlarmManager.RTC_WAKEUP, awakeTime, awakeIntent);
