I am trying to implement a push notification solution for android.I am following the steps given in the following tutorial http://www.androidhive.info/2012/10/android-push-notifications-using-google-cloud-messaging-gcm-php-and-mysql/
but when i tried to install the Google Cloud Messaging for Android Library using the android sdk(i am using the latest sdk) i don't find it the extras module like you can see in this picture
This is really strange. Is there any solution?
Select the 'Show Obsolete Packages' option in Packages menu and you will be able to view it and install.
