How to Share your Location in AR in 15 minutes or less [Tutorial]


Here's an easy demo that lets you share a certain location AR using with Unity, ARFoundation, and echoAR.. The full demo can also be found on echoAR's GitHub.


If you don't have an echoAR API key yet, make sure to register for FREE at echoAR.



PinLocation Package

  • Clone this repo
  • In your existing project of Unity-ARFoundation-echoAR, from the toolbar on top select Assets > Import Package > Custom Package...
  • Select echoAR-PinLocation.unitypackage located in this repo and click Open
  • Click All and then Import
  • From the Project tab in Unity, go to Assets > AR Foundation > Scenes > PinLocation
  • Open the scene PinLocationAR
  • Edit ShareButtonHandler.cs file in the same directory
  • Find the ShareLocation() function and place your API key and optional * configurations
  • From the project tab, go to Assets > AR Foundation > Scripts
  • Overwrite PlaceOnPlane.cs with the corresponding file in this repo


echoAR Console

  • In the Content page under Manage, select the option to upload new files
  • Upload both files in the directory MapPinConsoleObject located in this repo


  • This project utilizes Native Share for Android & iOS from the Unity Asset Store
  • In your Unity project, go to Asset Store and download the asset above in its entirety


Note: These instructions assume that you are familiar with building and running the project for your desired platform (iOS, Android…) Please consult external resources if you are having difficulties in this process.

  • In Build Settings, after selecting iOS, ensure that you have selected the correct scene that is AR Foundation/Scenes/PinLocation/PinLocationAR. If this option is not available, click Add Open Scenes and try again by looking at the end of the list.


When share button at the bottom-center of the screen is touched, user location is determined with LocationService in Unity. The location is sent within an HTTP POST request to echoAR’s API.

  • In the echoAR console, go to Data tab under Manage
  • The location should be seen in the Global database table on this page
