多次获取相同的 Firebase 通知

Question

我正在使用 firebase 来获取订阅主题的通知。 FirebaseMessagingService 多次收到相同的通知。我已经尝试了所有提供的解决方案，但对我没有任何帮助。任何帮助将不胜感激。提前致谢。

  <service android:name=".Firebase.MyFirebaseMessagingService" >
            <intent-filter>
                <action android:name="com.google.firebase.MESSAGING_EVENT" />

            </intent-filter>
        </service>

FirebaseMessagingService 尽管我发送单个通知，但此覆盖函数被多次调用。

public class MyFirebaseMessagingService extends FirebaseMessagingService {

    private static final String TAG = "MyFirebaseMsgService";

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        //Displaying data in log
        //It is optional
        String refreshedToken = FirebaseInstanceId.getInstance().getToken();
        Log.d(TAG,refreshedToken);
        Log.d(TAG, "From: " + remoteMessage.getFrom());
        Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());

        //Calling method to generate notification
        sendNotification(remoteMessage.getNotification().getBody());
    }

 private void sendNotification(String messageBody) {
        Intent intent = new Intent(this, MainActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
                PendingIntent.FLAG_ONE_SHOT);

        Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.bazaar_noti_small)
                .setContentTitle("Price Updated")
                .setContentText(messageBody)
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);

        NotificationManager notificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

        notificationManager.notify(0, notificationBuilder.build());
    }
}

你能告诉我你的 sendNotification() 函数吗？

以下代码是我的示例推送通知。我

private void sendNotification(String title,String messageBody)
    {
        Intent viewIntent = new Intent(getApplicationContext(), MainActivity.class);

        PendingIntent contentIntent = PendingIntent.getActivity(
                getApplicationContext(),
                0,
                viewIntent, // add this
                PendingIntent.FLAG_UPDATE_CURRENT);

        Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(getNotificationIcon())
                .setTicker("Test App")
                .setContentTitle(title)
                .setContentText(messageBody)
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setContentIntent(contentIntent);

        NotificationManager notificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

        //Random r = new Random();
        //int randomNumber = r.nextInt(100 - 0) + 0;

        notificationManager.notify(1, notificationBuilder.build());
    }

中的第二个参数

PendingIntent contentIntent = PendingIntent.getActivity(
                getApplicationContext(),
                0,
                viewIntent,
                PendingIntent.FLAG_UPDATE_CURRENT);

被称为请求代码对于每个通知需要是唯一的
