当应用程序没有运行广播接收器不工作 [英] BroadcastReceiver not working when app is not running

问题描述

在我的清单文件我已经宣布了接收器。 （如下图）

In my manifest file I have declared the receiver. (as follows)

<receiver android:name=".OnAlarmReceive" />

但是，一旦我关闭了我的申请，我不能够得到报警和通知。显然，我的广播接收器到的onReceive 呼叫从来没有。

public class OnAlarmReceive extends BroadcastReceiver
{
@Override
public void onReceive(Context context, Intent arg1)
   {
       //various stuff
   }
}

在MainActivity里面，我的报警管理器类是作为如下：

Inside the MainActivity, my alarm manager class is as the follows.

AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
    Intent intent = new Intent("MY_ALARM_NOTIFICATION");
    intent.setClass(this, OnAlarmReceive.class);
    intent.putExtra("message", message);
    PendingIntent pendingIntent = PendingIntent
            .getBroadcast(MainActivity.this, 0, intent,
                    PendingIntent.FLAG_UPDATE_CURRENT);

    Calendar timeCal = Calendar.getInstance();
    timeCal.set(Calendar.HOUR_OF_DAY, hour);
    timeCal.set(Calendar.MINUTE, minutes);

    alarmManager.set(AlarmManager.RTC_WAKEUP, timeCal.getTimeInMillis(), pendingIntent);

和我的表现为是如下：

    <receiver android:name=".OnAlarmReceive">
    <intent-filter android:priority="1">  
        <action android:name="MY_ALARM_NOTIFICATION"/>  
    </intent-filter>  
</receiver>  

我应该怎么才能收到通知/报警，即使我已经关闭我的应用程序做的。后台服务？

What should I do in order to receive the notifications/alarms even if I have shut off my app. Background service ?

推荐答案

您code工作正常！

所有你所要做的就是改变这一行：

All you have to do is to change this line:

alarmManager.set(AlarmManager.RTC_WAKEUP, timeCal.getTimeInMillis(),
pendingIntent);

这一行：

alarmManager.set(AlarmManager.ELAPSED_REALTIME_WAKEUP, 
SystemClock.elapsedRealtime() + 5000, pendingIntent);

和在的onReceive的code将5000毫秒后运行（5秒），即使应用程序没有运行

And the code in the "onReceive" will run after 5000ms (5sec) even when app is not running
