无法在Qt Android中安排本地通知

Question

我正在尝试使用Qt为Android应用创建本地计划的通知。我正在遵循以下答案：Unable to schedule notification with AlarmManager on Android (using Qt)，但我无法使其正常运行。

下面是代码 notificationclient.h：

#ifndef NOTIFICATIONCLIENT_H
#define NOTIFICATIONCLIENT_H

#include <QObject>

class NotificationClient : public QObject
{

    explicit NotificationClient(QObject *parent = 0);

    int createNotification(Qstring title, Qstring content);



};

#endif // NOTIFICATIONCLIENT_H

notificationclient.cpp

#include "notificationclient.h"

#include <QtAndroidExtras/QAndroidJniObject>

NotificationClient::NotificationClient(QObject *parent)
    : QObject(parent)
{

}



int NotificationClient::createNotification(Qstring title, Qstring content);
{
    QAndroidJniObject javaNotification = QAndroidJniObject;
    QAndroidJniObject::callStaticMethod<void>("ScheduledNotifications",
                                       "createNotification",
                                       "(Ljava/lang/String;)V",
                                       javaNotification.object<jstring>());
}

ScheduleNotification.java

class ScheduledNotifications {
    static public int notification_id = 0;
    static int scheduleNotification(String title, String content, int futureInMilliseconds) {
        ++notification_id;

        Intent notificationIntent = new Intent(QtNative.activity(),  NotificationPublisher.class);
        notificationIntent.putExtra(NotificationPublisher.NOTIFICATION_ID, notification_id);
        notificationIntent.putExtra(NotificationPublisher.NOTIFICATION, createNotification(title,content));
        PendingIntent pendingIntent = PendingIntent.getBroadcast(QtNative.activity(), 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);

        AlarmManager alarmManager = (AlarmManager)QtNative.activity().getSystemService(Context.ALARM_SERVICE);
        alarmManager.set(AlarmManager.RTC_WAKEUP, /*futureInMilliseconds*/0, pendingIntent);

        Log.d("!" ,"Scheduled");
        return notification_id;
    }

    static public Notification createNotification(String title, String content) {
            Notification.Builder builder = new Notification.Builder(QtNative.activity());


            builder.setContentTitle(title);
            builder.setContentText(content);
            return builder.build();
    }
}

NotificationPublisher.java

class NotificationPublisher extends BroadcastReceiver {

    public static String NOTIFICATION_ID = "notification-id";
    public static String NOTIFICATION = "notification";

    public void onReceive(Context context, Intent intent) {//Called when its time to show the notification ...

        Log.d("!", "Notified");
        NotificationManager notificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);

        Notification notification = intent.getParcelableExtra(NOTIFICATION);
        int id = intent.getIntExtra(NOTIFICATION_ID, 0);
        notificationManager.notify(id, notification);

    }
}

我不太确定该怎么做。如果有人可以在Qt中提供带有本地通知的适当示例，那将真的很有帮助

谢谢！
