FCM消息推送在一加6手机上无法工作

Question

FCM推送通知在以下设备中正常工作：当设备位于后台、前台时，以及当应用程序通过从托盘中刷卡关闭时。品牌名称（Android版）Micromax（5.1）摩托罗拉（7.1.1）诺基亚（8.1.0）三星（8.0.0）Nexus（8.1.0）小米（7.1.2）

但在oneplus中，当应用程序通过从托盘中刷卡关闭时，fcm通知不起作用，但当应用程序位于前台和后台时，fcm通知可以正常工作。设备版本OnePlus 8.1.0

但当我手动关闭应用程序的电池优化选项时，无论如何fcm推送通知在Oneplus设备中都能正常工作

我用这种方式向服务器发送令牌

{

            .addOnCompleteListener(new OnCompleteListener<InstanceIdResult>() {
                @Override
                public void onComplete(@NonNull Task<InstanceIdResult> task)
                {
                    String registrationId = task.getResult().getToken();
                    sendTokenToServer(registrationId);
                }
            });
}

任何小小的帮助都将不胜感激

Answer 1

试试这个代码

Uri defaultSoundUri = 
RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
 NotificationCompat.Builder notificationBuilder = new 
NotificationCompat.Builder(this)
 .setSmallIcon(R.drawable.ic_notif_icon)
  .setContentTitle("testTitle")
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setChannelId("testChannelId") // set channel id
.setContentIntent(pendingIntent);

Answer 2

在这些设备（如OnePlus、Huawie、OPPO）中，他们使用的是基于android操作系统的定制版操作系统，可能是在电池优化时，强制关闭FCM的后台服务，我们没有收到任何通知。

Answer 3

这种情况的发生是因为打瞌睡模式，您可以在fcm中将推送通知消息优先级从后端设置为高消息优先级来克服这种情况。请参阅is文档
