安卓:为什么系统重启后没有报警通知停止重启、通知、系统

2023-09-05 04:36:20 作者:莫负韶华

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);

}

 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);
}

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>

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.
