android – 一些Oreo设备没有获得推送通知


三星S8 / S5 / J2 / Note3成功获得Firebase推送通知应用程序被杀死,在后台或前台,

但如果应用程序被杀,Infinix Note 5(Android One-Oreo)和Oppo F9(Oreo)没有得到推送通知,如果应用程序处于后台或前台,它们可以正常工作.

我经历了很多文章,thisthis,提到中国手机存在这个问题,并且用户方面有一些工作要让这些通知在他们的手机上工作.

但我想知道从开发方面是否有可能在每个Android设备上进行通知工作.

我的目标是API 27,这是我的代码

public class FirebaseMessagingService  extends com.google.firebase.messaging.FirebaseMessagingService {


  @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        super.onMessageReceived(remoteMessage);
        String from = remoteMessage.getFrom();
        Map data = remoteMessage.getData();

        JSONObject jsonObject = new JSONObject();
        Set keys = remoteMessage.getData().keySet();
        for (String key : keys) {
            try {
                jsonObject.put(key, remoteMessage.getData().get(key));
            } catch (JSONException e) {
                e.printStackTrace();
            }
        }

        message= jsonObject.getString("message");

         sendNotification(message, urlToOpen);



    private void sendNotification(final String msg, final String urlToOpen) {


        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);

        String channelId = getString(R.string.notification_channel_general);
        Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

        NotificationCompat.Builder notificationBuilder =
                new NotificationCompat.Builder(this, channelId)
                        .setSmallIcon(R.drawable.notification_icon)
                        .setContentTitle("App Name")
                        .setContentText(msg)
                        .setAutoCancel(true)
                        .setSound(defaultSoundUri)
                        .setPriority(Notification.PRIORITY_MAX)
                        .setContentIntent(pendingIntent);

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


        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            NotificationChannel channel = new NotificationChannel(channelId,
                    "App Channel",
                    NotificationManager.IMPORTANCE_HIGH);
            notificationManager.createNotificationChannel(channel);
        }

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