buildscript { 
    repositories { 
     jcenter() 
    } 
    dependencies { 
     classpath 'com.google.gms:google-services:3.0.0' 

     classpath 'com.android.tools.build:gradle:2.2.2' 
     // NOTE: Do not place your application dependencies here; they belong 
     // in the individual module build.gradle files 
    } 
} 

allprojects { 
    repositories { 
     jcenter() 
     maven { url "https://jitpack.io" }
