推送通知无法与NotificationCompat.BigPictureStyle配合使用（无法为通知增加视图）

Question

我正在尝试在通知托盘中显示大图图像。这是代码

Intent resultIntent = new Intent(mCtx, PostsActivity.class);
        resultIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        resultIntent.putExtra("notificationId", data.get("id"));
        PendingIntent pendingIntent = PendingIntent.getActivity(mCtx, 0, resultIntent, PendingIntent.FLAG_ONE_SHOT);
 Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        Bitmap bitmap = getBitmapfromUrl
                (data.get("image"));
        String title = data.get("title");
        String body = data.get("body");
        //Bitmap picture = BitmapFactory.decodeResource(bitmap);
        final NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(mCtx, Constants.CHANNEL_ID)
                        .setSmallIcon(R.mipmap.ic_launcher)
                        .setContentTitle(title)
                        .setContentText(body)
                        .setAutoCancel(true)
                        .setSound(soundUri)
                        .setStyle(new NotificationCompat.BigPictureStyle().bigPicture(bitmap))
                        .setContentIntent(pendingIntent);

                NotificationManager mNotifyMgr =
                        (NotificationManager) ctx.getSystemService(NOTIFICATION_SERVICE);

                if (mNotifyMgr != null) {
                    mNotifyMgr.notify(0, mBuilder.build());
                } 


 public Bitmap getBitmapfromUrl(String imageUrl) {
        try {
            URL url = new URL(imageUrl);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setDoInput(true);
            connection.connect();
            InputStream input = connection.getInputStream();
            return BitmapFactory.decodeStream(input);

        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
    }

  

AndroidMenifest.xml

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

  

为BigPictureStyle应用代码时出现Logcat错误。

我可以在没有NotificationCompat.BigPictureStyle（）的情况下接收通知。但是，当我使用新的 NotificationCompat.BigPictureStyle（）时，我不会收到通知。我在整个互联网上搜索，但没有任何帮助。我不知道怎么了。

请帮助！
