在Android SDK管理器中找不到Google云消息传递（GCM）库

Question

我想在我的android应用程序中实现推送通知。所以我想从android SDK管理器安装Google云消息传递库，但我在sdk管理器的Extras部分中看不到它。有人建议更新sdk管理器将使其他人建议您不要使用GCM库，而我只需要使用Google Play服务库。两者中的哪一个是正确的，我该如何解决？

Answer 1

您将拥有Google Play服务库。使用该库最适合推送通知

Answer 2

To write your client application, use the GCM APIs. To use this API, you must set up your project to use the Google Play services SDK, as described in Setup Google Play Services SDK.

Caution: When you add the Play Services library to your project, be sure to add it with resources, as described in Setup Google Play Services SDK. The key point is that you must reference the library—simply adding a .jar file to your Eclipse project will not work. You must follow the directions for referencing a library, or your app won't be able to access the library's resources
