By Humus1 on Thu, 10/10/2019 - 11:40

Guys I started following Mathew Halberg's make in 6 minute augmented reality app

https://www.youtube.com/watch?v=lMFn8eTwePI

. Im using unity 2018.3.0f 2 and Vuforia Engine v8.5.8

and im getting these following errors. On screen in unity Play mode i can see my character and i can move him in the unity play mode

but when i complie the apk file n run it on my android i cant my character .

My android lacks gyroscope so i guess this is why i get 2nd error but i ran that apk file on my friend's android he has gyroscope and android 7.8 something OS. I should get this error but why does the same thing happen on my friend's android i cant figure out please help. Also when i run the game in unity play mode my character disappears and then reappears.

Ive followed the video to the letter.

I set up ground plane stage and Plane Finder.

Assign Ground Plane Stage to Contetn positioning behavior script

Plane finder Behavior as interactive On my plane Finder i add the character object and use a function to move him and also the toggle button

I set my character as child object of Ground Plane Stage

Hi,

In order to use Ground Plane the devices on which you are installing the game need to be supported by ARCore or Fusion. Below links to check if your phone is supported.

Hi,

I have tested my unity project in Pocophone f1,Nokia 6.1 plus which does have AR core support but still iam getting the same issue.Previously when iam working with Vuforia version 8.0.10 it was working fine.When i update it to 8.3.8 i got this issue.

ThankYou,

Hi,

Yes i have imported ARCore inside my Unity Project and have set the vufoira configuration as mentioned here:

Hi,

Does it work? or are you receiving the same error?

Thank you.

Hi

It is not working. Smart terrain and positional device tracker are always null. But in iOS, it is working fine. Also it is working some of the high end android mobiles like Samsung S8 plus.
