helllo_ar_java emulator failed to create AR session
SPECIFIC ISSUE ENCOUNTERED
Failed to create AR session com.google.ar.core.exceptions.fatalexception
hello_ar_java displays this error and a black screen when trying to run in emulator.
I downloaded the google play services for AR apk and installed on the emulator. I have tried many different hardware profiles and API versions and none will successfully display.
Front camera is set to emulated in AVD and rear is virtualscene. Logcat logs are pasted below.
Some APIs display this error, and in some, the app just crashes.

Arcore SDK for Andriod version v1.43.
It can detect 2 cameras. But fails to find the default camera. Physical cameras don't match device profile. Camera not found. camera_id=0, cameras count=2
@devbridie Could you suggest which version of AR core SDK can be used while this bug is being fixed including compatible OS version and API level.
Same issue happens for me, not just on hello_ar_java, but every time I try to create a new AR Session (vial new Session(context) ) on a virtual device, in any project.
I tried several device images (Android API 35, Android Vanilla IceCream Android 14 ("UpsideDownCake"),
and both Google_Play_Services_for_AR_1.44.0_x86_for_emulator.apk and Google_Play_Services_for_AR_1.45.0_x86_for_emulator.apk.
Not a single one works, they all throw the same FatalException.
Did anyone find a work-around?
Facing the same issue with Google_Play_Services_for_AR_1.45.0_x86_for_emulator.apk, API 35
@SandeepHub @khattab-dev @symmetry-max Did you find a solution to this?
Still same issue after updating the emulator to 35.2.10 and Google Play Services for AR to 1.46.0.
the same for com.google.ar:core:1.47.0 Baklava and UpsideDownCake Update: in my case this might be an issue: Only x86-based Android Emulator architectures are supported. Other architectures such as arm64-v8a, armeabi-v7, are not currently supported. https://developers.google.com/ar/develop/java/emulator#create_avd
You need to make sure that the image you're using IS NOT doing an ABI translation like this
As from the example the Baklava is doing a translated ABI into arm64-v8a which prevents it from running the ARCore as stated here

@Desz01ate Thanks for the answer.
In my Android Studio dialog, ABI translation is not displayed, so I'm having trouble understanding what you mean.
On the official documentation, it is stated that "Only x86-based Android Emulator architectures are supported. Other architectures such as arm64-v8a, armeabi-v7, are not currently supported."
Are you suggesting to use an arm64 system image?
I just tried it again using the latest v1.50.0 which was released 4 days ago, but it still has exactly the same error.
I'm also getting the same error in my app when running it in the emulator.
Reproduces with Google_Play_Services_for_AR_1.50.0_x86_for_emulator

@Desz01ate I've tested 2 emulators with 2 images, one with translated ABI and one with not translated ABI:
Error appears on both images.
Dear @devbridie this issue has been open for over a year now, and chance it will get seen and fixed?
If someone is still looking for a solution, API 33 images work for me, with Preferred ABI x86_64.
