AlarmManager不要作为expectly [英] AlarmManager don't run as expectly
问题描述
正如你建议我使用AlarmManager代替定时器,我想,程序会运行。结果
但不幸的是,事实并非如此。或者,更好,总是不...
As you suggested me to use AlarmManager instead of Timer, I thought, the program will run.
But unfortunately, it does not. Or, better, not always...
这是我的code:
long millis = 0;
this.alarmMgr = (AlarmManager)this.main.getSystemService(Context.ALARM_SERVICE);
this.checkPendingIntent = PendingIntent.getBroadcast(this.main, 0,
new Intent(this.main, AlarmReceiver.class), 0);
if(frequency.compareTo("1HOUR") == 0)
millis = 3600 * 1000;
if(frequency.compareTo("12HOUR") == 0)
millis = 12 * 3600 * 1000;
if(frequency.compareTo("1DAY") == 0)
millis = 24 * 3600 * 1000;
if(frequency.compareTo("1WEEK") == 0)
millis = 7 * 24 * 3600 * 1000;
this.alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP,
System.currentTimeMillis(), millis, this.checkPendingIntent);
我期待那悬而未决的意图(AlarmReceiver)将会被调用每X毫秒,但事实并非如此。结果
我可以在我的手机日志中看到,它不会被调用,并在日志我的服务器中(接收器发送一个HTTP请求),没有收到请求。
I'm expecting that the pending intent (AlarmReceiver) will be called every X milliseconds, but it does not.
I can see in the logs of my phone, that it will not be called, and in the log of my server (the receiver sends an HTTP-Request), that no requests are received.
很奇怪的是,它运行一段时间,但我不能重现的情况。
VERY strange is, that sometime it runs, but I can't reproduce the situation.
有人会说我什么我做错了?
Can someone say me what am I doing wrong?
多谢结果

推荐答案
这是如何使用的闹钟一个简单的例子
This is a simple example of how to use the Alarm
Calendar now = Calendar.getInstance();
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, yourHour);
calendar.set(Calendar.MINUTE, yourMin);
calendar.set(Calendar.SECOND, youSec);
if (calendar.before(now)) { //if time passed
calendar.add(Calendar.DATE,1);
}
Intent intent = new Intent(Context.this, DestinationActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity
(Settings.this,123456, intent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager am = (AlarmManager)getSystemService(Activity.ALARM_SERVICE);
am.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
AlarmManager.INTERVAL_DAY,pendingIntent);
使用setRepeating如果你想每天重复闹钟。结果
如果我想知道我用setAlarm(.. .. .. ..),而不是
Use setRepeating if you want your alarm to be Repeated daily.
If you don`t want use setAlarm(..,..,..,..) instead
