Camera is closed exception on takePicture()

Hi, I am using camera2 in my app. Generally camera works fine for most of the users but for some users when they try capture image an exception is thrown with message “Camera is closed.” While this error occurs camera is actually actively working on UI, so not sure why this error is happening.

Code I am using to capture image is :

imageCapture.takePicture(outputFileOptions, ContextCompat.getMainExecutor(getContext()),
                    new ImageCapture.OnImageSavedCallback() {
                        @Override
                        public void onImageSaved(ImageCapture.OutputFileResults outputFileResults) {

                            imagePath = FileProvider
                                    .getUriForFile(getContext(), getContext().getPackageName() + ".provider", imageFile);
                            checkImageOrientation();
                        }

                        @Override
                        public void onError(ImageCaptureException error) {
                            // error.getMessage() --> Camera is closed.
                        }
                    });

Please let me know how to fix this. Thank you!

It’s a emulator issue. Change emulators camera setting Emulated instead of VirtualScene, will fix the issue

I am also getting this errof but only for android API 31 and using Back Camera.
I tested the CameraXBasic sample on many pixels devices and different CameraX versions and always getting this log bellow. When testing on lower Android Api or Using Front camera i could not reproduce this.
