Use these dependencies for the project build.gradle
dependencies {
classpath 'com.android.tools.build:gradle:2.0.0-alpha3'
classpath 'com.google.gms:google-services:2.0.0-alpha3'
}
and put this at the end of the app-level build.gradle file (after the dependencies).
apply plugin: 'com.google.gms.google-services'
I have no clue why putting this at the end (and not at the beginning ) solves the error.

Ok… So trying to put an end to all problems you guys have faced with my solution
This is my final app level gradle
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
defaultConfig {
applicationId "your-app-name"
minSdkVersion 16
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
repositories {
jcenter()
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.google.android.gms:play-services:8.4.0'
compile 'com.android.support:design:23.1.1'
compile 'com.mcxiaoke.volley:library:1.0.6@aar'
}
apply plugin: 'com.google.gms.google-services'
and this is my final project level gradle
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.0.0-alpha3'
classpath 'com.google.gms:google-services:2.0.0-alpha3'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
}
}
Compare this with your own gradle files, and add or modify any values which are different from what I've written.
