I'm working with google cloud message in a android project, for this reason I am importing the google play services library but in my project also I need import the facebookSDK library, my problem is that the project not work when I have including the google play services library and facebookSDK library What is the correct form for import these libraries I think that G.C.M not work fine, it is because the Facebook SDK project has for default the google play services library
Adding Java Build Path reference to android_sdk\extras\google\google_play_services\libproject\google-play-services_lib\libs\google_play_services.jar file will fix the issue
