CameraX photo capture freeze (frequently)
Mohammad Sajib Al Seraj
Hello,
I am facing a similar problem (https://stackoverflow.com/questions/70706754/camerax-video-recording-freezes-and-generates-empty-video-file/71356133#71356133)
for capturing photo. I am trying to take multiple photos using our app. Preview
and taking the first photo is always fine. But when I try to take a second or third
photo, camera stops taking photos.
Log is attached here. Thanks in advance.
imageCapture.takePicture(image, ContextCompat.getMainExecutor(this),
new ImageCapture.OnImageSavedCallback() {
@Override
public void onImageSaved(@NonNull ImageCapture.OutputFileResults outputFileResults) {
runOnUiThread(() -> {
onPictureTakenOption(photoFilePath);
});
}
@Override
public void onError(@NonNull ImageCaptureException exception) {
}
}
);

- Could you provide the model number (SM-XXXX) of the devices which you can reproduce the issue?
- What is the issue occurrence rate?
- Are there any reproduce steps that is easier to reproduce the issue?
- Is it possible to provide a sample project with the source code to reproduce the issue? Or, could you help to check whether the issue can be reproduced by enabling NIGHT mode in the CameraXBasic sample app?

1. Could you provide the model number (SM-XXXX) of the devices which you can reproduce the issue? Samsung S10+ (SM-G975U1) and A71 5G (SM-A716V)
2. What is the issue occurrence rate? – The occurrence rate is very high (one per 2-3 events).
3. Are there any reproduce steps that is easier to reproduce the issue? – In our app(I have attached one screenshot of our app) we need to take multiple photos. This issue is only happening for either the second or third capture, not the first capture.
4. Is it possible to provide a sample project with the source code to reproduce the issue? Or, could you help to check whether the issue can be reproduced by enabling NIGHT mode in the CameraXBasic sample app? – I checked with CameraXBasic sample app which is working fine. I have attached a java file from my project where I have implemented image capture.
NB:
I have tested our app with the CameraX vendor extension not supported devices(Pixel 4a and
other devices) where I didn’t face this issue(not a single time).
Thanks

I might need more time to reproduce the issue. But I have one question after checking the code. I found you always call the InitCamera() function to unbind all and recreate use cases after capturing an image. I'm thinking whether it is necessary. It seems there is no change related to the uses' case settings. Maybe you can try to NOT unbind all and recreate use cases after capturing an image. This might be a faster approach to fix the issue before I reproduce it and find a solution for it.
