Answer 1

In your project level build.gradle add like following:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.2'
        classpath 'com.google.gms:google-services:3.0.0'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

While your App level build.gradle should look like this:

apply plugin: 'com.android.application'
dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile "com.google.android.gms:play-services-gcm:8.3.0"
}
apply plugin: 'com.google.gms.google-services'

Make sure to add apply plugin: 'com.google.gms.google-services' as last line in your app level gradle file.

You should only apply the com.android.application plugin.

Applying the java plugin as well will result in a build error. Reference : http://tools.android.com/tech-docs/new-build-system/user-guide

The dependencies you have added are fine. You can remove the "apply plugin: 'com.google.gms.google-services'" entry.
