Camera is closed exception on takePicture()

[akashsarkar188]

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!

thank you for reporting the issue! To get on this issue, may you narrow down the scope, if you could have a small app to demo it, that is great; os version, device model(s). Unless this consistently happens on most devices(Pixel device is easy to get by in our org).

[akashsarkar188]

Hey @ggfan , Sorry for replying late, actually this is happening in our production application. So basically the app doesnt crash so I dont really have any clear logs. I am just able to get some message which says "camera is closed" in the onError callback.

We are also getting this error, reported on Samsung Galaxy A52 5G, I have logs for the same. We are using CameraX stable version. The user is taking pictures continuously and it occurs in between. Please find the logs below. Thanks Ram

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.

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

[kotoMJ]

I am afraid it's not just emulator issue. I can see the happening for users in production with device Samsung Galaxy S22 Ultra. This is definitely not just an emulator issue.

I can just add the scenario which was the cause in my particular case and how I fixed that.

For me this issue happened when the app was sent to the background after triggering a picture but before picture was saved. In this case camera fired ImageCaptureException. I simply try catch this exception and return null instead of photoFile. No more ImageCaptureException in production since then.

Hope it will help to the others.

Getting same exception in Device Manufacturer- OPPO OS Version- 12 Device Name- OP4EF3L1

imageCapture1.takePicture( outputOptions, ContextCompat.getMainExecutor(requireContext()), object : ImageCapture.OnImageSavedCallback { override fun onError(exc: ImageCaptureException) { "Camera is closed" }

[AdarshRevankar]

For me, it just so happened that I forgot to perform image.close() operation over the past captured images in the following method, override fun onCaptureSuccess(image: ImageProxy)

Performing takePicture multiple times without performing image.close() imageProxy might also create this issue of androidx.camera.core.ImageCaptureException: Camera is closed.

Hope this will be useful to someone ! Cheers 😄 ✌️

ContextCompat.getMainExecutor(getContext())

imageCapture.takePicture( outputOptions, Executors.newSingleThreadExecutor(), object : ImageCapture.OnImageSavedCallback{})

@akashsarkar188 try using separated thread for the executor(). Its worked for me.
