android - How to update Google Play Services to 9.8.7

Question

I am trying to implement firebase in android project but always getting:
Google Play services out of date. Requires 9877000 but found 9683480
My graddle project/app files look like:

...
compile 'com.google.firebase:firebase-core:9.8.0'
    compile 'com.google.firebase:firebase-database:9.8.0'
    compile 'com.google.firebase:firebase-auth:9.8.0'

}

apply plugin: 'com.google.gms.google-services'

and

dependencies {
        classpath 'com.android.tools.build:gradle:2.2.2'
        classpath 'com.google.gms:google-services:3.0.0'

I created Nexus S emulator with API 23 and Target: Android 6.0 (Google APIs) x86_64

Inside emulator Google App Services version is 9.6.83

What should I do to be able to run firebase as don't know what to install or update anymore :/
I am new to android and don't know if I am missing something small.
