Didn't find class "com.google.android.gms.common.GoogleApiAvailability"

Hi,

I'm developing an AR application for Android devices. But the problem is, that I can't use the Image Tracking function. The image don't get recognized. Logcat shows following error that might be the reason:

Does anybody have any ideas how to fix this problem? The error shows up as soon as the AR Session script is activated in Unity.

I'm using:
Unity 2019.3.0f3
AR Foundation 3.1.0 - preview.3
AR Subsystem 3.1.0 - preview.2
ARCore XR Plugin 3.1.0 - preview.2
XR Interaction Subsystems 1.0.1
XR Interaction Toolkit 0.9.2 - preview
XR Legal Input Helpers 1.3.8
XR Management 3.05

Device: Samsung Galaxy S8 with Android 8

Thanks in advanced!

 

Hi,

I have resolved the issue
Navigate to Assets-> plugins-> Android open the mainTemplete.gradle file in notepad and add dependency as implementation 'com.google.android.gmslay-services-auth:17.0.0' in gradle file under dependencies.

 

I'm trying to create the simplest AR application and in my project, there is no Plugins directory. Am I missing something?
