FCM数据消息未在通知点击时打开应用

Question

如果用户没有在前台单击通知（通常应该发生），我想打开我的应用程序。当我发送FCM display-message时，该应用程序在单击通知后打开，但是当我发送data-message时，该应用程序在单击通知时未打开。

这是 MyAndroidFirebaseMsgService 类：

public class MyAndroidFirebaseMsgService extends FirebaseMessagingService {
    private static final String TAG = "MyAndroidFCMService";
    Bitmap bitmap;
    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        if (remoteMessage.getData().get("imgUrl") == null && remoteMessage.getData().get("webUrl") == null) {
            createNotification(remoteMessage.getNotification().getBody(), remoteMessage.getNotification().getTitle());
        } else if (remoteMessage.getData().get("imgUrl") != null && remoteMessage.getData().get("webUrl") != null) {
            String imageUrl = remoteMessage.getData().get("imgUrl");
            String websiteUrl = remoteMessage.getData().get("webUrl");
            createNotificationBoth(remoteMessage.getNotification().getBody(), remoteMessage.getNotification().getTitle(), imageUrl, websiteUrl);
        } else if (remoteMessage.getData().get("imgUrl") != null) {
            String imageUrl = remoteMessage.getData().get("imgUrl");
            //createNotificationWithImage(remoteMessage.getNotification().getBody(), remoteMessage.getNotification().getTitle(), imageUrl);
            createNotificationWithImage(remoteMessage.getData().get("body"), remoteMessage.getData().get("title"), imageUrl);
        } else if (remoteMessage.getData().get("webUrl") != null) {
            String websiteUrl = remoteMessage.getData().get("webUrl");
            createNotificationWithUrl(remoteMessage.getNotification().getBody(), remoteMessage.getNotification().getTitle(), websiteUrl);
        } else {
            String body = "Nothing Received";
            String title = "No Title";
            createNotification(body, title);
        }

    }

    private void createNotificationWithUrl(String messageBody, String messageTitle, String websiteUrl) {

        Intent intent = new Intent( this , MyAndroidFirebaseMsgService.class );
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent resultIntent = PendingIntent.getActivity( this , 0, intent,
                PendingIntent.FLAG_ONE_SHOT);
        Uri notificationSoundURI = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder mNotificationBuilder = new NotificationCompat.Builder( this)
                .setSmallIcon(getApplicationInfo().icon)
                .setContentTitle(messageTitle)
                .setContentText(messageBody)
                .setAutoCancel( true )
                .setSound(notificationSoundURI)
                .setContentIntent(resultIntent);
        NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(0, mNotificationBuilder.build());
    }

    private void createNotificationWithImage(String messageBody, String messageTitle, String imageUrl) {

        bitmap = getBitmapFromUrl(imageUrl);
        Intent intent = new Intent( this , MyAndroidFirebaseMsgService.class );
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent resultIntent = PendingIntent.getActivity( this , 0, intent,
                PendingIntent.FLAG_ONE_SHOT);
        Uri notificationSoundURI = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder mNotificationBuilder = new NotificationCompat.Builder( this)
                .setSmallIcon(getApplicationInfo().icon)
                .setContentTitle(messageTitle)
                .setContentText(messageBody)
                .setStyle(new NotificationCompat.BigPictureStyle()
                        .bigPicture(bitmap))
                .setAutoCancel( true )
                .setSound(notificationSoundURI)
                .setContentIntent(resultIntent);
        NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(0, mNotificationBuilder.build());
    }

    private void createNotificationBoth(String messageBody, String messageTitle, String imageUrl, String websiteUrl) {

        bitmap = getBitmapFromUrl(imageUrl);
        Intent intent = new Intent( this , MyAndroidFirebaseMsgService.class );
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent resultIntent = PendingIntent.getActivity( this , 0, intent,
                PendingIntent.FLAG_ONE_SHOT);
        Uri notificationSoundURI = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder mNotificationBuilder = new NotificationCompat.Builder( this)
                .setSmallIcon(getApplicationInfo().icon)
                .setContentTitle(messageTitle)
                .setContentText(messageBody)
                .setStyle(new NotificationCompat.BigPictureStyle()
                        .bigPicture(bitmap))
                .setAutoCancel( true )
                .setSound(notificationSoundURI)
                .setContentIntent(resultIntent);
        NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(0, mNotificationBuilder.build());

    }

    private void createNotification( String messageBody, String messageTitle) {

        Intent intent = new Intent( this , MyAndroidFirebaseMsgService.class );
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent resultIntent = PendingIntent.getActivity( this , 0, intent,
                PendingIntent.FLAG_ONE_SHOT);
        Uri notificationSoundURI = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder mNotificationBuilder = new NotificationCompat.Builder( this)
                .setSmallIcon(getApplicationInfo().icon)
                .setContentTitle(messageTitle)
                .setContentText(messageBody)
                .setAutoCancel( true )
                .setSound(notificationSoundURI)
                .setContentIntent(resultIntent);
        NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(0, mNotificationBuilder.build());
    }
}

发送到应用程序的

数据有效载荷：

$fields = array(
    'registration_ids' => $registration_ids,
    'data' => array(

        "title" => $message['title'],
        "body" => $message['message'],
        "imgUrl" => $message['imgUrl'],
    )
);

顺便说一句，我只想发送data-message，因为我希望它在应用程序处于后台时显示BigImage。
