本文介绍了某些设备在几小时后收到Gcm通知的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
设备通过端口5228上的 TCP连接到Google Play服务 设备应使用端口443作为回退，如果端口5228被阻止，但显然他们并没有使用回退（有时发生在我的多个设备上）。 设备每发送一次心跳数据包到Google Play服务您可以检查连接状态，心跳间隔，连接地址和端口等。拨号 *＃*＃426＃ *＃* 在设备上 Open port 5228
Configure your routers, so they don't kill inactive tcp connections before waiting at least 15 minutes
我正在尝试使用gcm通知。我的服务器代码工作正常，我得到了成功作为承认。
问题是通知正常发送：
1）在大多数设备中，即时收到通知。 在Google Nexus，sony手机上测试。 $ b 2）其他设备也会在几个小时后收到通知。是，小时。测试Karbonn，Micromax的一些手机。注意： 所有设备连接到相同的WiFi，所以网络连接不成问题。在服务器端使用PHP; 关于此主题有几个未解答的问题。我特此列出其中的一些：
gcm通知不适用于micromax等设备

任何其他有类似问题的人都会附上您的问题。
更正尝试失败： $ b
我也经历了几个问题，其中开发人员发现他们的解决方案如从 onHandleIntent（）
GcmBroadcastReceiverpleteWakefulIntent（intent）;或将 delay_while_ideal 值更改为<$ c
或者单独提及接收者和注册意图 - 过滤器

如何解决设备无法连接时的常见问题在Google Play服务上使用wifi或经常失去连接：

I am trying to use gcm notification. My server code is working fine and I am getting success as acknowledgment.
The problem is notification is getting sent properly :
1) In most of devices notification is received instantaneously. Tested on google nexus,sony phones.
2) Other devices are also receiving notification but after several hours. Yes, hours. Tested on Karbonn, Micromax some phones.
Note:
All the devices are connected to the same wifi so network connectivity not an issue . Using php at server side; There are several unanswered questions regarding this topic . I am hereby listing some of them:
gcm notification is not working on some devices like micromax
One device doesn't receive push notifications (GCM)
Push notifications delay with GCM
Anyone else having similar problem attach your question too.
Failed trials of rectification:
I have also made changes to code after going through several questions in which the developers found their solution like removing this line of code from onHandleIntent()
GcmBroadcastReceiverpleteWakefulIntent(intent);Or changing delay_while_ideal value to true/false in server code.
Or separately mentioning receiver and registration intent-filter

解决方案- GCM works through Google Play Services
- Devices connect to Google Play Services through TCP on port 5228
- Devices should use port 443 as fallback if port 5228 is blocked, but apparently they just don't use the fallback sometimes (happened to multiple of my devices)
- Device sends a heartbeat packet to Google Play Services every 28 minutes on mobile and 15 minutes on wifi
- You can check the connection state, heartbeat interval, connection address and port, etc. dialing *#*#426#*#* on a device
How to fix common issues when devices don't connect to Google Play Services on wifi or lose connection frequently:
