fcm 推送通知在一加 6 手机中不起作用 [英] fcm push notification not working in one plus 6 mobile

问题描述

当设备处于后台、前台以及通过从托盘滑动关闭应用程序时，FCM 推送通知在以下设备中正常工作.品牌名称(安卓版)Micromax (5.1)摩托罗拉 (7.1.1)诺基亚 (8.1.0)三星 (8.0.0)连结 (8.1.0)小米 (7.1.2)

FCM push notification is working in following devices properly when the device is in the background, foreground and also when an app is close by swiping from a tray. Brandname (android-Version) Micromax (5.1) Motorola (7.1.1) Nokia (8.1.0) Samsung (8.0.0) Nexus (8.1.0) xiaomi (7.1.2)

但是在oneplus的情况下，通过从托盘滑动关闭应用程序时fcm通知不起作用，但当应用程序在前台和后台时正常工作.设备版本一加8.1.0

But in case of oneplus, fcm notification is not working when an app is closed by swiping from a tray, but work properly when an app is in foreground and background. Device Version OnePlus 8.1.0

但是当我为我的应用手动关闭电池优化选项时，在所有情况下，fcm 推送通知在 Oneplus 设备中都能正常工作

我以这种方式向服务器发送令牌

And I am sending token to server in this way

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

任何小的帮助将不胜感激

Any small help will be appreciated

推荐答案

发生这种情况是因为 打盹模式 你可以在 fcm 中通过将来自后端的推送通知消息优先级设置为高消息优先级来克服这个问题，看看是 文档

this happens because of Doze Mode you can overcome this in fcm by setting the push notification message priority from backend side to be high message priority take a look at is documentation
