问题
I want to use GCM Service in my application.
I have referred to the following link (Android Developer: Google GCM) but was not able to install the GCM Library in my eclipse.
From the SDK manager I am not getting GCM Library in the Extras Folder.
Can anyone please help me?

I had similar issues and it was resolved once I updated Android SDK Tools to revision 20 and Android Platform SDK Tools to revision 12. Rev 19/11 would not shown up Extras > Google Cloud Messaging for Android Library in SDK Manager. And make sure that you restart SDK manager after updating.
It should then show up in SDK manager as shown bellow:

For me just an update don't work. But try to download and install new Android SDK from http://developer.android.com/sdk/index.html. After installing this it finally shows me new libraries in extras.
