And

My gradle file :

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.0"

    defaultConfig {
        minSdkVersion 19
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:24.0.0'
    compile "com.google.android.gms:play-services-gcm:9.0.0"

}

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

The problem might comes from one of the libraries your app depends on, library that depends itself on Google Play Services as well. You might using an older version of the Google Play Services SDK and its still relies on the fact that Google API Client class is an interface. This breaks backward compatibility because of the transitive dependencies of libraries. Please check if you use the latest version or remove the dependecy if possible.
