Steps to reproduce:

  1. Open Unity Hub and create a new project from the “3D” template.

  2. In Unity Editor open build settings and switch platform to Android.

  3. Open player settings, turn off Auto Graphics API and remove Vulkan from the list, such that only OpenGles3 remains.

  4. Scroll down and set minimum API level to Android 7.0 ‘Nougat’ (API level 24).

  5. Set Target API level to Android 10.0 (API level 29).

  6. Set scripting backend to IL2CPP.

  7. Under target architectures, turn off ARMv7 and turn on ARM64.

  8. Import custom package “ardk-1.1.0.unitypackage” and click “Yes, just for these files” in the Script Updating Consent pop up window.

  9. Import custom package “ardk-examples-1.1.0.unitypackage”.

  10. Close Unity Editor, open Unity Hub and open the newly created project which was created in step 1.

  11. Add ARDK_MockWorld layer.

  12. In the project panel go to Assets > ARDKExamples > Image Detection and open the ImageDetection.unity scene file.

  13. In Unity Editor open build settings and switch platform to Android.

  14. Make sure the device is set to Developer Mode with USB Debugging turned on.

Sorry to hear that you’re facing an issue with the ImageDetection example. We tried to reproduce the issue on our end, however, we were able to build and run the application on an android device successfully.

In your case, if the app has been built and deployed to a device and still shows a black screen for the camera, then there might be camera permission on the device that’s not being allowed at runtime. To fix that, check the app permissions and enable camera, location, and storage permissions.

Hope this helps!
