更新间隔时间时警报管理器不工作 [英] alarm manager not working while updating interval time

问题描述

阅读所有质量检查后，我没有得到任何适当的解决方案. 我有2个问题
1.即使我仅在清单中注册接收器，警报也会触发两次.(不是通过代码)
2.当我更新警报间隔时间时，它会随机触发

after reading all the QA i didnt get any proper solution. I have 2 problems
1. Alarm fires twice even if i register my receiver only in manifest.(not by code)
2. when i update interval time of alarm it gets fires randomly

这是我设置闹钟的方法

 public void AlarmCall(int min) {

    Intent intent = new Intent(context, AlarmReceiver.class);
    PendingIntent pintent = PendingIntent.getBroadcast(context,0 , intent, 0);
    alarm = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
    cancelAlarm(alarm,pintent);
    if(Build.VERSION.SDK_INT<18) {
        alarm.set(AlarmManager.RTC_WAKEUP, 1000 * 60 * min, pintent);
    }
    else if(Build.VERSION.SDK_INT>=19 && Build.VERSION.SDK_INT<=22)
    {            alarm.setRepeating(AlarmManager.RTC_WAKEUP,System.currentTimeMillis(), 1000*60*min, pintent);
    }
    else if(Build.VERSION.SDK_INT>=23)
    {         alarm.setExactAndAllowWhileIdle(AlarmManager.RTC_WAKEUP,1000*60*min,pintent);
    }
}

取消警报的方法:

public void cancelAlarm(AlarmManager alarm,PendingIntent p)
{
    alarm.cancel(p);
    Log.d("Alarm","Alarm Cancle");
}

在我的项目应用程序类中，我必须以10分钟的时间间隔启动警报，并且它可以正常工作，根据用户输入的值，我需要更新时间间隔. 因此，我使用int min输入值调用此方法并取消了第一个警报.
但是在棉花糖中，它每5秒钟触发一次，而奇巧棒棒糖则随机地触发.
甚至使用setExact()方法进行检查

in my project Application class i have to start alarm with 10 min time interval and it works fine , according to user input value i need to update time interval.
so i call this method with int min input value and cancel first alarm.
but in marshmallow it fires at every 5 seconds, and kitkat lollipop it fires randmoly.
even checked with setExact() method

推荐答案

我遇到了同样的问题，使用setWindow解决了问题

I had the same issue, use setWindow solved the problem

long repeatInterval = 1000 * 60 * min;
long triggerTime = SystemClock.elapsedRealtime()
                    + repeatInterval;

AlarmManager alarms = (AlarmManager) this.getSystemService(
                    Context.ALARM_SERVICE);

if (Build.VERSION.SDK_INT >= 19) 
{
          alarms.setWindow(AlarmManager.RTC_WAKEUP, 
                     triggerTime, 
                     repeatInterval,
                     pendingIntent);
}else{
          alarms.setInexactRepeating(AlarmManager.RTC_WAKEUP,
                    triggerTime,
                    repeatInterval,
                    pendingIntent);}
