_Include the following details (edit as applicable):_

- **Issue category** : Semantic Segmentation
- **Device type & OS version** : Android /Pixel 3 on Android 11
- **Host machine & OS version** : PC / Windows 10
- **Issue Environment** : On Device
- **Xcode version** : N/A
- **ARDK version** : 1.2.0
- **Unity version** : 2020.3.24f1

Description of the issue:  
I am trying to run the Semantic Segmentation scene from the examples package on Android. I have not touched any scripts, I simply want to run the scene on device.

Once built, the app opens and asked for camera permission, then waits for a couple seconds, starts the camera, then it crashes. I have run the scene in the editor but do not see any errors.

I have tried leaving API Compatibility Level at .Net Standard 2.0 , only using OpenGLES3, and unchecking Dynamic Batching.

My best guess is that it is associated with the ardk client platform because it is mentioned in the Logcat error (see bottom of post). Anyone else have this issue, I appreciate any help / suggestions!

Below are screenshots of my build settings:

I recreated the Semantic Segmentation Example scene based on the Unity settings you provided (with OpenGLES3, Dynamic Batching, and .NET 4x). While using a lower Target API Level, I was able to build and run without issue, though built outside of Android Studio. Please try changing your Target API Level to Android 10.0 (API level 29). To target a higher API level, or if you are experiencing issues related to Android Studio, please double check the Building for Android 11 (API level 30) and higher directions, the Google Play Services for AR settings and your Gradle version.

Thanks for the response Erik.

I was indeed targeting Android 11 and followed the steps you listed but no luck. However, changing my build target to Android 10 did the trick! I appreciate your help.
