Run AR Apps in Android Emulator

Use the Android Emulator to test AR scenarios without a physical device. The Android Emulator lets you run ARCore apps in a virtual environment with an emulated device that you control.

Set up your development environment

Software requirements:

Android Studio 3.1 or later.
Android Emulator 27.2.9 or later.

Hardware requirements:

If you're using Sceneform in your app, you'll also need:
Development machine that supports OpenGL ES 3.0 or higher.

Get Android Studio and SDK tools for ARCore

Install Android Studio 3.1 or later.
In Android Studio, go to Preferences > Appearance and Behavior > System Settings > Android SDK.
Select the SDK Platforms tab and check Show Package Details.

Under Android 8.1 (Oreo), select:
Google APIs Intel x86 Atom System Image API Level 27, version 4 or later.
Select the SDK Tools tab and add Android Emulator 27.2.9 or later.
Click OK to install the selected pacakges and tools.
Click OK again to confirm changes.
Accept the license agreement for the Component Installer.
Click Finish.

Create a virtual device with AR support

You can follow the Android Studio instructions to Create a Virtual Device with AR support.

Configure the virtual device

Select the Pixel or Pixel 2 hardware profile.
Select the Oreo: API Level 27: x86: Android 8.1 (Google APIs) system image.
Confirm that your virtual device is configured correctly:
- Go to Verify Configuration > Show Advanced Settings.
- Make sure that Camera Back is set to VirtualScene.

Configure the emulator to support Sceneform

Sceneform requires OpenGL ES 3.0 or higher.

Make sure your emulator is configured to use the latest version of OpenGL ES:
- Click in the running emulator's toolbar.
- Select Settings > Advanced > OpenGL ES API level > Renderer maximum (up to OpenGL ES 3.1).
- Restart the emulator. When prompted, do not save the current state.
After restarting the emulator, briefly interact with the emulated deivce, then check whether OpenGL ES 3.0 or higher is being used by grepping the device logs:
```
adb logcat | grep eglMakeCurrent
```
If you see ver 3 0 or higher version, then you can run Sceneform apps in the emulator:
```
… …  …  … D EGL_emulation: eglMakeCurrent: 0xebe63540: ver 3 0 (tinfo 0xd104cb40)
```
If you see a lower version, then your desktop GPU does not support OpenGL ES 3.0 and you must instead use a physical supported device to run Sceneform apps.

Run your app

Test an ARCore app on an AR-supported virtual device in the emulator. To do this, you can follow the Android Studio instructions to Run an app in the Android Emulator.

Update Google Play Services for AR

The version of Google Play Services for AR on the emulator is likely out of date. Follow these instructions to update it:

Download the latest Google_Play_Services_for_AR_1.14.0_x86_for_emulator.apk from the GitHub releases page.
Install the downloaded APK into each AVD you'd like to use:

Start the desired AVD, then drag the downloaded APK onto the running emulator, or install it using adb while the virtual device is running:
```
adb install -r Google_Play_Services_for_AR_1.14.0_x86_for_emulator.apk
```

Repeat these steps process for any additional AVDs you'd like to use.

Control the virtual scene

When your app connects to ARCore, you’ll see an overlay describing how to control the camera and a status bar below the emulator window.

Move the virtual camera

Press and hold Option (macOS) or Alt (Linux or Windows) to access camera movement controls. Use the following controls to move the camera:

Platform	Action	What to do
macOS	Move left or right	Hold Option + press A or D
	Move down or up	Hold Option + press Q or E
	Move forward or back	Hold Option + press W or S
	Change device orientation	Hold Option + move mouse
Linux or Windows	Move left or right	Hold Alt + press A or D
	Move down or up	Hold Alt + press Q or E
	Move forward or back	Hold Alt + press W or S
	Change device orientation	Hold Alt + move mouse

Release Option or Alt to return to interactive mode in the emulator.

Use the Virtual Sensors tab in Extended controls for more precise device positioning.

Add Augmented Images to the scene

Load images into the emulator’s simulated environment to test Augmented Images.

Use the Camera tab in Extended controls to add or modify Scene images. There are two image locations, one on the wall and one on the table.

To view these image locations in the scene, launch your emulator, then move the camera to the dining room area through the door behind the camera’s starting position.

Troubleshooting tips

If your ARCore app launches and you see an "AR Core not supported" message, check the revision on your system image. Make sure you are using API Level 27 Revision 4.
If your ARCore app fails to open the camera when it launches, make sure that Camera Back is set to VirtualScene, as described in the configuration steps above.
