Quickstart for Android

Get started with targeting your ARCore Unity apps to Android.

This guide shows you how to set up your development environment and try out an ARCore sample app.

Requirements

Hardware

  • An ARCore supported device

  • A USB cable to connect your device to your development machine

Software

Get the ARCore SDK for Unity

  1. Download ARCore SDK for Unity 1.12.0 or later.
    The SDK is downloaded as arcore-unity-sdk-1.12.0.unitypackage.

Create a new project and import the SDK

  1. Open Unity and create a new 3D project.

  2. Unity 2019 only: Select Window > Package Manager and install the following packages:

    • Multiplayer HLAPI (required by the CloudAnchors sample)
    • XR Legacy Input Helpers (required by Instant Preview, which uses the TrackedPoseDriver)
  3. Import the ARCore SDK for Unity:

    1. Select Assets > Import Package > Custom Package.

    2. Select the arcore-unity-sdk-1.12.0.unitypackage that you downloaded.

    3. In the Importing Package dialog, make sure that all package options are selected and click Import.

Open the sample scene

  1. In the Unity Project window, you can find the HelloAR sample in:
    Assets/GoogleARCore/Examples/HelloAR/Scenes/.

Configure project settings

  1. Go to File > Build Settings to open the Build Settings window.
  2. Select Android and click Switch Platform.
  3. In the Build Settings window, click Player Settings.

Build and run the sample app

  1. Enable developer options and USB debugging on your device.

  2. Connect your device to your development machine.

  3. In the Unity Build Settings window, click Build and Run.
    Unity builds your project into an Android APK, installs it on your device, and launches it.

  4. Move your device around until ARCore starts detecting and visualizing planes.

  5. Tap a plane to put an Andy Android object on it.

  6. (Optional) Use Android logcat to view log messages or Android Device Monitor to analyze the device more comprehensively.
