Compilare ARToolKit su Android Studio 3

Le istruzioni per installare ARToolKit su Android Studio sono piuttosto vecchie e di fatto non funzionano nella configurazione attuale (sono state scritte nel 2016)

Per fare funzionare gli esempi, dopo avere compilato la libreria nell'NDK (come da istruzioni), si devono modificare i file di progetto come segue (vedi linee evidenziate in giallo)

---------------------------

buildscript {
    repositories {
        jcenter()
    }
    
    dependencies {
        classpath 'com.android.tools.build:gradle-experimental:0.11.1'

        // NOTE: Do not place your application dependencies here; they belong        // in the individual module build.gradle files    }
}

allprojects {
    repositories {
        jcenter()
    }
}
