What do you mean? Why are you talking about AVD Manager? Yet, this issue is not present on emulators.

Can you set your Camera ID in AVD Manager under Advanced Settings to "0"?

Hi there,

Thanks for the email - it looks similar to the logs in a bug that was filed recently. Please see our developers response here: https://issuetracker.google.com/issues/140751456#comment8 pasted here as well:

 

The crash in comment #1 looks to me as if the HAL has crashed. CameraX is calling getCameraCharacteristics() with what should be a valid camera, but an exception is thrown. This exception is thrown if the camera id doesn't exist however we always query for camera ids via getCameraIdList(). This unfortunately is a condition that CameraX is unable to recover from. We are looking into if there are reasons why CameraX might cause the camera HAL to go into such a state, but as of now we don't have a reliable way of reproducing it.

Thanks
