Install Google Play Services Library
安装 Google Play 服务库
For client side implementation of GCM use this link
对于 GCM 的客户端实现，请使用此链接
For server side purposes follow the tutorial
对于服务器端的目的，请遵循教程
Pls note that the tutorial explains how you can send messages to individual devices using the registration id and not to all devices at one go.
请注意，本教程解释了如何使用注册 ID 向单个设备而不是一次性向所有设备发送消息。
[Update]
[更新]
I observed that still some people are using the deprecated library - GCM for android.
我观察到仍有一些人在使用已弃用的库 - GCM for android。
"Google Cloud Messaging for Android" is deprecated and no more used.GCM API's are now available as part of "Google Play Services".
“Android 版 Google Cloud Messaging”已弃用，不再使用。GCM API 现在可作为“Google Play 服务”的一部分使用。
Eventhough @anubhav's answer is correct for the asked question it is not recommended.
尽管@anubhav 的回答对提出的问题是正确的，但不建议这样做。

Seems like this package is now obsolete. In order to see it in SDK Manager I had to check "Show obsolete packages" in the "Packages" menu
好像这个包现在已经过时了。为了在 SDK Manager 中看到它，我必须在“Packages”菜单中选中“Show obsolete packages”
Edit (clarification of my answer)
编辑（澄清我的答案）
I encountered this problem when trying to run Maven Android SDK Deployer. The version of the SDK deployer I used, was expecting gcm package installed (at least when running the deployer in its default configuration).
我在尝试运行时遇到了这个问题Maven Android SDK Deployer。我使用的 SDK 部署器版本期望安装 gcm 包（至少在以默认配置运行部署器时）。
For other purposes, it's recommended to use the newer Google Play Servicesinstead, as stated in one of the answers here.
出于其他目的，建议改用较新的Google Play Services，如此处的其中一个答案中所述。

Is there any solution?

Use something newer than that tutorial. The old GCM API was deprecated last May and was replaced with a new one.

Just tick the "Obsolete" checkbox in Android SDK Manager popup.
只需在 Android SDK 管理器弹出窗口中勾选“过时”复选框。
