问题描述：

Intent intent = new Intent(this, SplashActivity.class);
                Bundle bundle = new Bundle();
                bundle.putString("splash", psd);
                bundle.putString("targetId", targetId);
                intent.putExtras(bundle);
                intent.setAction(psd);
                intent.setAction(targetId);
                intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
                PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(), id, intent,
                        0);


                Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
                NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                        .setSmallIcon(android.R.drawable.ic_notification_overlay)
                        .setContentTitle(title)
                        .setContentText(remoteMessage.getData().get("body"))
                        .setAutoCancel(true)
                        .setStyle(new NotificationCompat.BigTextStyle().bigText("" + remoteMessage.getData().get("body")))
                        .setContentIntent(pendingIntent)
                        .setSound(defaultSoundUri);

                NotificationCompat.InboxStyle inboxStyle =
                        new NotificationCompat.InboxStyle();
                String[] events = new String[6];
                inboxStyle.setBigContentTitle("" + title);
                for (int i = 0; i < events.length; i++) {
                    inboxStyle.addLine(events[i]);
                }

                //.setContentIntent(pendingIntent);
                NotificationManager notificationManager =
                        (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
                notificationManager.notify(id, notificationBuilder.build());

它曾经工作过，不知道在 Android O 等新 Android 设备上发生了什么.我没有尝试回到旧设备，但它发生在像素上.

It used to be working, no clue what's happening on new Android devices like Android O. I didn't try back going to old devices, but it's happening on pixel.

试试这个代码，它对我来说非常适合.

try this code it works perfectly for me.

        Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

        PendingIntent resultPendingIntent = PendingIntent.getActivity(this, 0, resultIntent, PendingIntent.FLAG_CANCEL_CURRENT);

        NotificationCompat.InboxStyle inboxStyle = new NotificationCompat.InboxStyle();

        inboxStyle.addLine(message);

        NotificationManager mNotificationManager = (NotificationManager) getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);

        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
            NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(getApplicationContext(),"channel_01")
                    .setSmallIcon(R.mipmap.ic_launcher)
                    .setContentText(message)
                    .setContentIntent(resultPendingIntent)
                    .setAutoCancel(true)
                    .setPriority(Notification.PRIORITY_HIGH)
                    .setChannelId("channel_01")
                    .setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
                    .setStyle(inboxStyle)
                    .setContentTitle(Title);

            mNotificationManager.notify(Notification_ID, mBuilder.build());

            NotificationChannel channel = new NotificationChannel(Notification_ID, "Playback Notification", NotificationManager.IMPORTANCE_HIGH);
            channel.enableLights(true);
            channel.enableVibration(true);
            channel.setVibrationPattern(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400});
            assert mNotificationManager != null;
            mBuilder.setChannelId("channel_01");
            mNotificationManager.createNotificationChannel(channel);

        }else {
            NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(getApplicationContext(),Notification_ID)
                    .setSmallIcon(R.mipmap.ic_launcher)
                    .setContentTitle(Title)
                    .setContentIntent(resultPendingIntent)
                    .setContentText(message)
                    .setStyle(inboxStyle)
                    .setSound(soundUri)
                    .setAutoCancel(true);
            mNotificationManager.notify(Notification_ID, mBuilder.build());
        }
