具有高优先级的Firebase消息未从Doze Android 6+唤醒设备 [英] Firebase message with high priority not waking device from Doze android 6+

问题描述

我已经从使用GCM迁移项目到使用Firebase。

I have migrated my project from using GCM to use Firebase. Push notification comes through ok when the device is awake or been asleep recently but if I leave the device for say an hour, no push is sent until I wakeup the device.

当设备醒来或最近入睡时，推送通知通过ok，但是如果我离开设备一个小时，则不会发送任何推送，直到我唤醒设备。

The Android docs say that if you need to wake a device to deliver a message, then use FireBase with priority set to high. It also says that device Admin apps are not subject to Doze restrictions, my app is a device admin app.

Android文档说，如果您需要唤醒设备来传递消息，则可以将FireBase的优先级设置为高。它还说设备Admin应用程序不受Doze限制，我的应用程序是设备管理应用程序。

I thought I would mention that when I migrated the project from GCM to FCM, I only specified the package name in the firebase console and not the fingerprint.

我想我会提到从GCM迁移项目时到FCM，我只在Firebase控制台中指定了程序包名称，而不是指纹。

What I have tried.

我尝试过的内容。

1. Set priority to high

1. 将优先级设置为高

{ "time_to_live": 300000, "delay_while_idle": false, "android": { "priority": "high" }, "data": { "message": "PING_DEVICE", "time": "21/01/2018 16:20:28", "pushguid": "10062" }, "registration_ids": [ "eOMT........" ] }

Time to live is set so the message will come through eventually. delay_while_idle is set to false, this is ignored by FCM after sept 2016.

已设置生存时间，因此消息最终将通过。 delay_while_idle设置为false，2016年9月之后FCM将忽略它。

Device admin apps are not subject to Doze, mine is a device admin app but I have also explicitly added the app to the Doze whitelist found in Setting -> Battery -> Optimization. This was done manually through the settings app and NOT programmatically in code.

设备管理应用程序不受Doze的限制，我的设备管理应用程序受此限制，但我还已将该应用程序明确添加到设置->电池->优化中的打ze白名单中。这是通过设置应用程序手动完成的，而不是以编程方式在代码中完成的。

I have left my device to go to sleep for 3 hours and no push come through. I have also used adb to put the device into Doze. When adb puts the device in Doze no push is received, when adb takes the device out of Doze, the push comes through.

我已离开设备进入睡眠状态持续3个小时，没有任何推动力。我还使用过adb将设备放入Doze。当adb将设备置于打Do状态时，不会收到任何推送；当adb将设备从打ze状态退出时，推送将通过。

further thoughts I haven't tried.

My pushes are data messages. This is because I don't want the push to come to the notification bar on the device and have the user click it to execute the functionality. The user has no interaction with the device admin app. So a data message is handled by

我的推送是数据消息。这是因为我不希望推送出现在设备的通知栏上，而是让用户单击它来执行功能。用户与设备管理员应用没有交互。因此，数据消息由

onMessageReceived(RemoteMessage remoteMessage)

I believe notification messages do wake up the device, which is what I need but I want the app to handle the push, not the user. Could I have messages that are both notification and data but have onMessageRecievied handle the functionality?

有人可以经历过类似的事情或有任何解决方案吗？

Has anybody experienced anything similar or have any solutions to this?

我在下面找到了以下链接，您可以发送一条既包含通知又包含数据的消息，但是如果应用程序在后台，则显示通知但是仅在用户单击通知时才执行数据。这不是我想要的，因为我希望立即在onMessageRecived中执行数据。

I have found the following link below that says you can send a message which is both notification and data, but if the app is in the background, the notification is displayed but the data is only executed when the user clicks the notification. This is not what I want as I would like the data to execute in onMessageRecived straight away.

数据通知

我已经添加了以下代码和对应用的许可。该应用程序现在要求用户将应用程序列入Doze的白名单，因此我单击是。然后，我通过adb将设备放入Doze并发送了一个推送。直到我将设备退出打ze模式，一切都没有完成。因此，不幸的是，这不起作用。

I have added the following code and permission to the app. The app now asks the user to whitelist the app for Doze, so I clicked yes. I then via adb put the device in Doze and sent a push. Nothing came through until I took the device back out of doze mode. So, unfortunately, this does not work.

if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            Intent intent = new Intent();
            String packageName = getPackageName();
            PowerManager pm = (PowerManager) getSystemService(POWER_SERVICE);
            if (!pm.isIgnoringBatteryOptimizations(packageName)) {
                intent.setAction(Settings.ACTION_REQUEST_IGNORE_BATTERY_OPTIMIZATIONS);
                intent.setData(Uri.parse("package:" + packageName));
                startActivity(intent);
            }
        }

<uses-permission android:name="android.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS" />

我已经完成了进行进一步测试，以找出问题所在，并排除我的Web应用程序代码。我通过adb和使用的FireBase控制台将设备放入Doze，以发送推送。 推送正确完成 。这表明我的Web应用程序代码存在问题，该代码将所有推送信息发送到fcm端点。我将在今晚获得代码并稍后发布。

I have done further testing to try to isolate the problem and take my web application code out of the equation. I put the device into Doze via adb and the used FireBase console to send the push instead. The push came through correctly This tells me there is a problem with my web application code that sends all the push info to the fcm endpoint. I will get the code tonight and post later.

我刚刚做了更多测试。我将设备置于休眠状态，然后使用FireBase控制台发送带有2个键值对的数据消息。当设备处于打ze状态且应用程序位于前景（屏幕上）时，将通过推送并执行onMessageReceived。这很棒。但是，如果应用程序在BG中，则仅显示通知。我从文档中了解到，数据消息是通过Intent调度到启动器活动的，但是我的启动器应用程序不处理推送。处理推送的类称为MyAndroidFirebaseMsgService并扩展了FirebaseMessagingService。

i have just done some more testing. I placed the device into doze then used FireBase console to send a data message with 2 key-value pairs. When the device is in Doze and the app is in the foreground (on the screen), the push comes through and onMessageReceived executes. This is great. However, if the app is in the BG then only a notification is displayed. I understand that from the docs, the data messages are dispatched to the launcher activity via an Intent, but my launcher app does not handle the pushes.The class that handles the pushes is called MyAndroidFirebaseMsgService and extends FirebaseMessagingService.

如果应用程序在BG中，我是否必须将意图路由到此类？似乎有点饥饿，必须执行此操作。

Do i have to route the intent to this class in case the app is in the BG? Seems a bit starnge to have to do this. It was never the case in GCM.

此外，我不希望应用程序通过推送启动，因为这非常具有侵入性，因为设备用户可能会使用一个不同的应用程序。我的应用程序也是设备管理应用程序，因此99％的时间没有用户交互，它只是在设备上执行策略的客户端。

推荐答案

在遇到类似问题后，我设法使其正常工作。

After struggling with a similar issue I managed to get it to work.

我通过邮递员发送以下json数据：

I send following json data through postman:

{
  "data": {
    "body": "Test body from curl"
  },
  "registration_ids": ["Token"],
  "webpush": {
    "headers": {
      "Urgency": "high"
    }
  },
  "android": {
    "priority": "high"
  },
  "priority": 10
}

似乎最后一个 priority：10 对我来说是固定的。

It seems like the last "priority":10 is what's fixing it for me.

我在Firebase文档中找不到对此的任何引用，但是在已弃用的GCM文档中。 https://developers.google.com/cloud-messaging/concept-options

I could not find any reference to this in the Firebase documentation, but in the deprecated GCM documentation it's used. https://developers.google.com/cloud-messaging/concept-options
