Android Alarm Manager:OnReceive和PendingEvent服务未被调用

我尝试使用alarm manager在8:30发送意图，但alarm manager从不在8:30左右向接收者发送意图

我发现setAlarm（）方法中有一些问题，但我无法解决。 这里的许多帖子也提到了服务/接收者可能在清单文件中声明错误，但我不确定如何正确地将接收者和服务包含在清单中。我已经尝试合并包名，但仍然不起作用

public class EventAlarmReceiver extends WakefulBroadcastReceiver {
private AlarmManager alarmMgr;
private PendingIntent alarmIntent;
private PendingIntent alarmIntent1;

@Override
public void onReceive(Context context, Intent intent) {
    Intent service = new Intent(context, EventSchedulingService.class);
    startWakefulService(context, service);
}

public void setAlarm(Context context) {
        alarmMgr = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
        Intent intent = new Intent(context, EventSchedulingService.class);
        intent.putExtra("silent", true);
        alarmIntent = PendingIntent.getBroadcast(context, 0, intent, 0);

        Calendar calendar = Calendar.getInstance();
        calendar.setTimeInMillis(System.currentTimeMillis());
        // Set the alarm's trigger time to 8:30 a.m.
        calendar.set(Calendar.HOUR_OF_DAY,8);
        calendar.set(Calendar.MINUTE, 30);
        System.out.println(calendar.getTimeInMillis());
        alarmMgr.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), alarmIntent);
}
}

这是我的服务文件

package edu.ssui.smartsilent;

public class EventSchedulingService extends IntentService {

public EventSchedulingService() {
    super("EventSchedulingService");
}
@Override
protected void onHandleIntent(Intent intent) {
    Log.d("SService", "m1");
    AudioManager mgr = (AudioManager) getSystemService(Context.AUDIO_SERVICE); 
    if(intent.getExtras().getBoolean("silent")==true){
     mgr.setStreamVolume(AudioManager.STREAM_RING, 0, AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE);
     mgr.setStreamVolume(AudioManager.STREAM_ALARM, 0, AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE);
     mgr.setStreamVolume(AudioManager.STREAM_SYSTEM, 0, AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE);
     mgr.setStreamVolume(AudioManager.STREAM_NOTIFICATION, 0, AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE);
    }
    else
    {
         mgr.setStreamVolume(AudioManager.STREAM_RING, (int) (mgr.getStreamMaxVolume(AudioManager.STREAM_RING)*0.8), AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE);
         mgr.setStreamVolume(AudioManager.STREAM_ALARM, (int) (mgr.getStreamMaxVolume(AudioManager.STREAM_ALARM)*0.8), AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE);
         mgr.setStreamVolume(AudioManager.STREAM_SYSTEM, (int) (mgr.getStreamMaxVolume(AudioManager.STREAM_SYSTEM)*0.8), AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE);
         mgr.setStreamVolume(AudioManager.STREAM_NOTIFICATION, (int) (mgr.getStreamMaxVolume(AudioManager.STREAM_NOTIFICATION)*0.8), AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE);
    }
    Log.d("SService", "m1");
    EventAlarmReceiver.completeWakefulIntent(intent);

}

}

这是我的舱单

试试这个：

        alarmMgr = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
        Intent intent = new Intent(context, EventAlarmReceiver.class);
        intent.putExtra("silent", true);
        alarmIntent = PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

        Calendar calendar = Calendar.getInstance();
//        calendar.setTimeInMillis(System.currentTimeMillis());
        // Set the alarm's trigger time to 8:30 a.m.
        calendar.set(Calendar.HOUR_OF_DAY,8);
        calendar.set(Calendar.MINUTE, 30);
        System.out.println(calendar.getTimeInMillis());
        alarmMgr.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), alarmIntent);

还要放置调试日志，并确保您正在调用setAlarm（）。

将此权限添加到您的menifest：

<uses-permission android:name="com.android.alarm.permission.SET_ALARM"/>

您正在呼叫：

alarmIntent = PendingIntent.getBroadcast(context, 0, intent, 0);

getBroadcast（上下文，意图）将检索一个PendingEvent，该PendingEvent将使用您传递的上下文和意图执行广播。例如，它将调用Context.sendBroadcast（intent），它将意向发送给所有感兴趣的广播接收器

而不是做：

Intent intent = new Intent(context, EventSchedulingService.class);

尝试将BroadcastReceiver传递给意图构造函数
