It seems that play-services-ads has version 8.4.0 in audience-network-sdk module with dependencies to com.google.android.gms of lower version, exclude play-services-ads and add play-services-ads:10.2.0 afterwards :

dependencies {
    compile ('com.facebook.android:audience-network-sdk:4.+') {
        exclude module: 'play-services-ads'
    }
    compile(name:'unity-ads',ext:'aar')
    compile 'com.codemybrainsout.rating:ratingdialog:1.0.7'
    compile 'com.google.firebase:firebase-core:10.2.0'
    compile 'com.google.android.gms:play-services-ads:10.2.0'
}
