After configuring account kit sdk as
compile \'com.facebook.android:account-kit-sdk:4.+\'
and gradle sync it conflict with com.goo
Possibly the conflict of libraries can be the reason. See dependencies here; https://mvnrepository.com/artifact/com.facebook.android/account-kit-sdk/4.27.0
See if you could submit an issue with the facebook to update it.
Or if you need facebook for authentication only, you can use Facebook Android Sdk
