There is a conflict between play-service-ads used by audience-network-sdk facebook module and those used by firebase module. The following will fix it : 

compile('com.facebook.android:audience-network-sdk:4.+') {
    exclude module: 'play-services-ads'
}
compile 'com.google.android.gms:play-services-ads:11.0.2'

But after that, you have another conflict (not related to play-sevice this time) :

com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: com/facebook/ads/AbstractAdListener.class

This happens because com.adincube.sdk:AdinCube-Java-206ebf includes a dependency to com.adincube.partner:facebook which has the package name com.facebook.ads. I guess it's an unofficial modified package of facebook library. If you are sure you don't need this dependency, you can exclude it : 

compile('com.adincube.sdk:AdinCube-Java-206ebf:1.+@aar') {
    transitive = true
    exclude module: 'facebook'
}

Otherwise contact adincube.com for instructions about integrating their module with com.facebook.android:audience-network-sdk
