When does this error occur? ImageCaptureException: Camera is closed

[Ishank Nijhawan]

Hey, we introduced CameraX on our production app few months ago. It's working fine, but few of our users are constantly facing the following error while capturing an image.

       Non-fatal Exception: androidx.camera.core.ImageCaptureException: Camera is closed.
       at androidx.camera.core.imagecapture.TakePictureManager.abortRequests(TakePictureManager.java:161)
       at androidx.camera.core.ImageCapture.abortImageCaptureRequests(ImageCapture.java:787)
       at androidx.camera.core.ImageCapture.onStateDetached(ImageCapture.java:781)
       at androidx.camera.camera2.internal.Camera2CameraImpl.notifyStateDetachedToUseCases(Camera2CameraImpl.java:879)
       at androidx.camera.camera2.internal.Camera2CameraImpl.detachUseCases(Camera2CameraImpl.java:898)
       at androidx.camera.core.internal.CameraUseCaseAdapter.detachUseCases(CameraUseCaseAdapter.java:603)
       at androidx.camera.lifecycle.LifecycleCamera.onStop(LifecycleCamera.java:97)
       at androidx.camera.lifecycle.LifecycleCamera.suspend(LifecycleCamera.java:140)
       at androidx.camera.lifecycle.LifecycleCameraRepository.suspendUseCases(LifecycleCameraRepository.java:472)
       at androidx.camera.lifecycle.LifecycleCameraRepository.setInactive(LifecycleCameraRepository.java:417)

Due to this they're not able to move forward. My question is, when exactly does this error occur? I've also attached user's device screen recording, and as you can see he's not able to capture anything. But if I reproduce this on my device, it works just fine. 

Below are the device details for which users are facing issue

Samsung Galaxy S23 FE, Android version 14

Google Pixel 6a, Android 14

Redmi Note 8, Android 11

Oneplus Nord CE2, Android 14

Redmi Note 7 pro, Android 10

Any help would be greatly appreciated. Let me know if any further information is provided. Thanks!

Hi, thanks for reaching out to report the issue.  

Is there any chance that you can get the adb logcat files for us to analyze further ?

Hi Scott, unfortunately this exception is occurring for a production users so I don't have the exact logs. Plus, I'm not able to reproduce this issue on my device as well

I checked this github forum and the issue seems to be similar to mine https://github.com/android/camera-samples/issues/410

Kindly let me know if I can do anything to help you here

Hi Ishank, 

Sorry for the late reply!   Can you possibly tell if the issue is caused by takePicture being interrupted by lifecycleOwner stop event such as activity or fragment is stopped or destroyed ?  
I mean, if you log every takePicture onError event,  the takePicture interruption is also logged but it's not an actual issue that we have to worry about.  

But if it is not ,  then it's a real issue that we need to investigate further.  In our experience,  there are some devices having issue that takePicture will hang when using some certain resolutions.
