Unable to build and run ARSimpleProj with Android Studio -

i'm new ar , i've wanted try out artoolkit android studio.

when tried open example, arsimpleprog

it has error saying : plugin id 'com.android.model.application' not found.

and gradle project sync failed

i'm using android studio 2.1.2 , i've changed gradle below

since says must have android plugin version 2.1.2

and i've change gradle version 2.13 because read website

please follow instructions here setup native development artoolkit using android studio: http://artoolkit.org/documentation/doku.php?id=4_android:android_native

also have @ question here: gradle dsl cannot find sources()

artoolkit uses gradle experimental plugin building code. gradle script structure 'model' upfront correct. comes build.gradle (arsimpleproj) file.

you need build , setup environment instructed in artoolkit documentation.

hope helps
