i'm trying use google cloud messaging , have followed steps in https://developers.google.com/cloud-messaging/android/client when synchronize gradle files project this:

failed complete gradle execution. cause: [empty] 

i tried implement solution: android studio: failed complete gradle execution, cause empty , other similar solutions result same.

what solution problem? has happened this?

thaanks in advance!!

i found solution:

the problem lies not in gcm. problem arises when try compile app. used command;

gradlew assembledebug --stacktrace 

and threw error:

unable execute dex : method id not in [0 , 0xffff ] : 65536. 

i've solved steps described google here: building apps on 65k methods
