Vuforia ARcore Integration

Hi,

I need some help, I try to integrate Vuforia with ARCore following this link https://library.vuforia.com/content/vuforia-library/en/articles/Solution/arcore-with-vuforia.html

On Unity 2018.2, build with Gradle, mi device is a Galaxy S7 supported on the device list

Already do all stuff on the integration page, when try to build I get a Gradle error:

Build failed with an exception.

* What went wrong: Could not resolve all files for configuration ':releaseCompileClasspath'. > Could not find com.google.ar:core:1.3.0.   Searched in the following locations:

file:/C:/Android/extras/m2repository/com/google/ar/core/1.3.0/core-1.3.0.pom       file:/C:/Android/extras/m2repository/com/google/ar/core/1.3.0/core-1.3.0.jar       file:/C:/Android/extras/google/m2repository/com/google/ar/core/1.3.0/core-1.3.0.pom       file:/C:/Android/extras/google/m2repository/com/google/ar/core/1.3.0/core-1.3.0.jar       file:/C:/Android/extras/android/m2repository/com/google/ar/core/1.3.0/core-1.3.0.pom       file:/C:/Android/extras/android/m2repository/com/google/ar/core/1.3.0/core-1.3.0.jar       file:/C:/MyProject Unity 2018/Temp/gradleOut/libs/core-1.3.0.jar       file:/C:/MyProject Unity 2018/Temp/gradleOut/libs/core.jar

core-1.3.0.aar is on my Plugins\Android foleder, and the Project gradle file have the implementation 'com.google.ar:core:1.3.0'

I try to add @arr at the end of the implementation line and the error gone, but still can not see Vuforia running with ARCore

VuforiaRuntimeUtilities.GetActiveFusionProvider() always show VUFORIA_SENSOR_FUSION

is there a way to show all the available fusion providers? or check if arcore is enabled? (PLATFORM_SENSOR_FUSION??)

Is there any working vuforia unity example/Project to check for?

Regards
