应用程式被杀死时，Firebase不会收到消息-Android Oreo [英] Firebase don't receive message when app is killed - Android Oreo

问题描述

我知道关于这个主题有很多问题，但是在我的项目中没有人工作，我也不知道为什么.

I know that it have a lot of questions about this theme, but no one works in my project, and I don't know why.

我正在使用Firebase，如果我的应用程序处于打开"或在背景"中，他会收到消息，但是当我杀死我的应用程序时，不会再出现该消息了.

I'm using Firebase, if my app is OPEN or in BACKGROUND, his receive the message, but when I kill my app don't appear more.

C#中的代码以发送推送

Code in C# to send the push

async Task SendPushAndroidAsync(Device device, InArgumentRequest push, Notification notification)
    {
        var applicationID = configuration["Push:Google:ApplicationKey"];

        var data1 = new
        {
            to = DeviceIdEnviroment(device.Token, true),
            android = new {
                priority = "normal"
            },
            data = new
            {
                notificationId = notification.Id,
                title = notification.Title,
                message = notification.Message,
                type = notification.Type,
                date = notification.DateCreated.ToString("dd/MM/yyyy HH:mm"),
                android_channel_id = "channelidandroid"
            }
        };
        try
        {
            var jsonBody = JsonConvert.SerializeObject(data1);

            using (var httpRequest = new HttpRequestMessage(HttpMethod.Post, "https://fcm.googleapis.com/fcm/send"))
            {
                httpRequest.Headers.TryAddWithoutValidation("Authorization", "key=" + applicationID);
                httpRequest.Content = new StringContent(jsonBody, Encoding.UTF8, "application/json");

                using (var httpClient = new HttpClient())
                {
                    var result = await httpClient.SendAsync(httpRequest);

                    if (result.IsSuccessStatusCode)
                    {
                        await UpdateStatusNotification(notification, true);
                    }
                    else
                    {
                        await UpdateStatusNotification(notification, false, result.ReasonPhrase);
                    }
                }
            }
        }
        catch (Exception ex)
        {
            string error = ex.InnerException.Message;
            await UpdateStatusNotification(notification, false, error);
        }
    }​

谢谢！

推荐答案

消息priority

The message priority should not be nested inside android and should have value "high":

    var data1 = new
    {
        to = DeviceIdEnviroment(device.Token, true),
        priority = "high",
        data = new
        {
            notificationId = notification.Id,
            title = notification.Title,
            message = notification.Message,
            type = notification.Type,
            date = notification.DateCreated.ToString("dd/MM/yyyy HH:mm"),
            android_channel_id = "channelidandroid"
        }
    };

您可能没有收到该消息，因为该设备处于打ze模式或该应用处于应用待机模式.这是在文档中解释的.

It's possible you are not receiving the message because the device is in Doze Mode or the app is in App Standby Mode. This is explained in the documentation.

对邮件进行更改后，您可以致电

After making the change to your message you can confirm that it is received with high priortity by calling RemoteMessage.getOriginalPriority().
