Question

即使应用未处于活动状态，我也会尝试在特定时间实施发送通知但它只适用于应用程序处于活动状态（已打开）

创建

Intent notificationIntent = new Intent("android.media.action.DISPLAY_NOTIFICATION");
        notificationIntent.addCategory("android.intent.category.DEFAULT");
        PendingIntent broadcast = PendingIntent.getBroadcast(this, 100, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
        AlarmManager alarm = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);
        alarm.set(AlarmManager.RTC_WAKEUP, (System.currentTimeMillis() + (5 * 1000)), broadcast);

接收器类：

public class AlarmReceiver extends WakefulBroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Intent it = new Intent(context, StartActivity.class);
        createNotification(context, it, "new mensage", "body!", "this is a mensage");

    }

    public void createNotification(Context context, Intent intent, CharSequence ticker, CharSequence title, CharSequence descricao) {
        NotificationManager nm = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        PendingIntent p = PendingIntent.getActivity(context, 0, intent, 0);

        NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
        builder.setTicker(ticker);
        builder.setContentTitle(title);
        builder.setContentText(descricao);
        builder.setSmallIcon(R.drawable.icon);
        builder.setContentIntent(p);
        Notification n = builder.build();
        //create the notification
        n.vibrate = new long[]{150, 300, 150, 400};
        n.flags = Notification.FLAG_AUTO_CANCEL;
        nm.notify(R.drawable.icon, n);
        //create a vibration
        try {

            Uri som = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
            Ringtone toque = RingtoneManager.getRingtone(context, som);
            toque.play();
        } catch (Exception e) {
        }
    }
}

androidmanifest：

 <receiver android:name="com.example.atefhares.study_organizer.notifications_related.AlarmReceiver"
                android:enabled="true">
          <intent-filter>
                    <action android:name="android.media.action.DISPLAY_NOTIFICATION" />
                    <category android:name="android.intent.category.DEFAULT" />
         </intent-filter>
</receiver>

任何人都知道如何解决这个问题，拜托？

BroadcastReceiver仅在app处于活动状态时才起作用
