安卓：为什么系统重启后没有报警通知停止

本文介绍了安卓：为什么系统重启后没有报警通知停止的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我开发一个Android应用程序，应该火灾报警一天五次： - 时代的每一天不是恒定的 - 报警触发后，我会安排一个报警

我的问题是：报警通知工作1天，然后停止，并在设备重启两次通知不工作，我不知道现在是否有另一种方式来做到这一点，任何帮助将是非常AP preciated！

code： 我有这个函数来调用广播reciever

公共静态无效Start_Notifying（上下文的背景下）{     日历CAL = Calendar.getInstance（）;     cal.setTimeInMillis（System.currentTimeMillis的（））;     cal.add（Calendar.HOUR_OF_DAY，小时）;     cal.add（Calendar.MINUTE，分钟）;     意向意图=新的意图（背景下，OnetimeAlarmReceiver.class）;     intent.setAction（START_NOTIFYING）;     PendingIntent pendingIntent = PendingIntent.getBroadcast（背景下，notify.REQUEST_ code，意向，0）;     AlarmManager alarmManager =（AlarmManager）context.getSystemService（ALARM_SERVICE）;     alarmManager.set（AlarmManager.RTC_WAKEUP，cal.getTimeInMillis（），pendingIntent）;     SaveAlarmManager（alarmManager，pendingIntent）; }

oneTimeAlarmReciever的code

公共无效的onReceive（上下文的背景下，意图意图）{     main_menu.con =背景;     通知notifyDetails;     NotificationManager纳米=（NotificationManager）context.getSystemService（Context.NOTIFICATION_SERVICE）;     notifyDetails =新的通知（R.drawable.icon，S1，System.currentTimeMillis的（））;     PendingIntent pendingIntent = PendingIntent.getActivity（背景下，REQUEST_ code，新的意向（背景下，prayertimes.class），0）;     notifyDetails.setLatestEventInfo（上下文，S2 + notify.prayName，S3，pendingIntent）;     notifyDetails.sound = Uri.parse（PlaySound（））;     nm.notify（NOTIFICATION_ID，notifyDetails）;     main_menu.notify_me（）; }

notify_me的code（）

静态无效notify_me（）{     小时= pTime.num1;     分= pTime.num2;     Start_Notifying（CON）; }

解决方案   

为啥系统重新启动后报警通知停止

由于报警时间表清零重新启动。如果你想你的报警器重新启动后再次回升，则需要实施的BroadcastReceiver 的响应 RECEIVE_BOOT_COMPLETED 播出。该演示/ 在我的 WakefulIntentService 回购说明了这一点。

I am developing an android application that should fire an alarm five times a day: - the times in each day is not constant - after the alarm is fired I will schedule the next alarm.

My problem is : the alarm notification works for 1 day then it stops and also when the device is rebooted twice the notification doesn't work , I don't now if there is another way to do that , any help will be very appreciated!

Code: I have this function to call the broadcast reciever

public static void Start_Notifying(Context context){ Calendar cal = Calendar.getInstance(); cal.setTimeInMillis(System.currentTimeMillis()); cal.add(Calendar.HOUR_OF_DAY,hour); cal.add(Calendar.MINUTE, min); Intent intent = new Intent(context, OnetimeAlarmReceiver.class); intent.setAction("START_NOTIFYING"); PendingIntent pendingIntent = PendingIntent.getBroadcast(context, notify.REQUEST_CODE, intent,0); AlarmManager alarmManager = (AlarmManager) context.getSystemService(ALARM_SERVICE); alarmManager.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis() , pendingIntent); SaveAlarmManager(alarmManager, pendingIntent); }

the code of oneTimeAlarmReciever

public void onReceive(Context context, Intent intent) { main_menu.con = context; Notification notifyDetails; NotificationManager nm = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE); notifyDetails = new Notification(R.drawable.icon,s1,System.currentTimeMillis()); PendingIntent pendingIntent = PendingIntent.getActivity(context, REQUEST_CODE, new Intent(context, prayertimes.class), 0); notifyDetails.setLatestEventInfo(context,s2+ notify.prayName , s3, pendingIntent); notifyDetails.sound=Uri.parse(PlaySound()); nm.notify(NOTIFICATION_ID, notifyDetails); main_menu.notify_me(); }

The code of notify_me()

static void notify_me() { hour =pTime.num1; min =pTime.num2; Start_Notifying(con); }

In the manifest file

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"></uses-permission> <receiver class =".OnetimeAlarmReceiver" android:name="OnetimeAlarmReceiver"> <intent-filter> <action android:name="START_NOTIFYING" /> <action android:name="android.intent.action.BOOT_COMPLETED"> </action> <data android:mimeType="audio/ogg" /> </intent-filter> </receiver>

解决方案

why did the Alarm notification stop after system reboot

Because alarm schedules are cleared on a reboot. If you want to have your alarms pick up again after a reboot, you will need to implement a BroadcastReceiver that responds to the RECEIVE_BOOT_COMPLETED broadcast. The demo/ project in my WakefulIntentService repo demonstrates this.
