我在做一个报警系统,但我已经当手机处于关闭状态。该报警器不工作的问题。
I'm doing an alarm System but i've a problem when the phone is turned off.. The alarm doesn't work..
我设置去报警如下:
public void doIntents(Context context, long milis, Tratam trat){
cal=Calendar.getInstance();
alarmManager = (AlarmManager) context.getSystemService(Service.ALARM_SERVICE);
cal.setTimeInMillis(milis);
Intent intent = new Intent(context, OnAlarmReceiver.class);
pendingIntent = PendingIntent.getBroadcast(context, trat.getId(), intent, PendingIntent.FLAG_UPDATE_CURRENT);
alarmManager.set(AlarmManager.RTC_WAKEUP,milis ,pendingIntent);
}
报警工作正常时,电话被接通。
The Alarm works Ok when the phone is turned on..
我该怎么办?
感谢您!
是的,问题是你的应用程序没有运行在手机重新启动时。您需要注册,以便它收到一个消息的时候,手机重启可以接收BOOT_COMPLETED消息一个BroadcastReceiver。然后在BroadcastReceiver的,你可以重新安排这些报警或什么的。但我不认为有什么你可以做使你触发报警时,手机处于关闭状态。(如:使得手机开启)
Yea, the problem is your app isn't running when the phone restarts. You'll need to register a BroadcastReceiver that can receive the BOOT_COMPLETED message so it receives a message when the phone reboots. Then in the BroadcastReceiver you can either reschedule those alarms or whatever. But I don't think there's anything you can do about making your alarm trigger when the phone is off..(e.g. making the phone turn on)
<receiver android:name="MyBootReceiver"
android:enabled="true"
android:exported="true"
android:label="BootReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"></action>
</intent-filter>
</receiver>
