FCM推送通知在某些设备上不起作用

Question

我们用FCM创建了一个带有通知的聊天应用程序，我的代码是正确的，我的设备也得到了推送通知数据，但一些中国制造的设备，如vivo、oppo、一加、小米，不允许通知显示，除非我在各自厂商的受保护的应用程序列表中添加应用程序。他们有没有办法解决这个问题。

private NotificationManagerCompat notificationManager;

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    super.onMessageReceived(remoteMessage);

    Log.d("test","call");

    notificationManager = NotificationManagerCompat.from(this);
    sendNotification(remoteMessage.getNotification().getTitle(), remoteMessage.getNotification().getBody());
}

private void sendNotification(String title, String msg) {
    Intent resultIntent = new Intent(this, ActivitySplashScreen.class);

    String channelId = getString(R.string.chc);
    String channelName = "Message Notification";

    TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
    stackBuilder.addNextIntentWithParentStack(resultIntent);

    PendingIntent pendingIntent = stackBuilder.getPendingIntent(99, PendingIntent.FLAG_UPDATE_CURRENT);

    Notification notification = new NotificationCompat.Builder(this, channelId)
            .setSmallIcon(R.mipmap.ic_launcher_round)
            .setContentTitle(title)
            .setContentText(msg)
            .setPriority(NotificationCompat.PRIORITY_HIGH)
            .setCategory(NotificationCompat.CATEGORY_MESSAGE)
            .setContentIntent(pendingIntent)
            .build();

    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
        NotificationManager manager = getSystemService(NotificationManager.class);
        NotificationChannel channel = new NotificationChannel(channelId, channelName, NotificationManager.IMPORTANCE_HIGH);
        manager.createNotificationChannel(channel);
    }

    notificationManager.notify(10, notification);
}

我不认为这有一个通用的解决方案，因为你的应用程序是基于google-FCM，这意味着android设备定期与谷歌互联网服务通信。

据我所知，google-FCM在中国被屏蔽了
