This Java code converts android's ImageProxy to Bitmap.

Convert Android ImageProxy to Bitmap in Java.java

private Bitmap toBitmap(Image image) {
    Image.Plane[] planes = image.getPlanes();
    ByteBuffer yBuffer = planes[0].getBuffer();
    ByteBuffer uBuffer = planes[1].getBuffer();
    ByteBuffer vBuffer = planes[2].getBuffer();

    int ySize = yBuffer.remaining();
    int uSize = uBuffer.remaining();
    int vSize = vBuffer.remaining();

    byte[] nv21 = new byte[ySize + uSize + vSize];
    //U and V are swapped
    yBuffer.get(nv21, 0, ySize);
    vBuffer.get(nv21, ySize, vSize);
    uBuffer.get(nv21, ySize + vSize, uSize);

    YuvImage yuvImage = new YuvImage(nv21, ImageFormat.NV21, image.getWidth(), image.getHeight(), null);
    ByteArrayOutputStream out = new ByteArrayOutputStream();
    yuvImage.compressToJpeg(new Rect(0, 0, yuvImage.getWidth(), yuvImage.getHeight()), 75, out);

    byte[] imageBytes = out.toByteArray();
    return BitmapFactory.decodeByteArray(imageBytes, 0, imageBytes.length);
}

Getting distorted image like below

This is my code

public Bitmap imageProxyToBitmap(ImageProxy imageProxy) {
        ImageProxy.PlaneProxy[] planeProxies = imageProxy.getPlanes();

        ByteBuffer yBuffer = planeProxies[0].getBuffer();
        ByteBuffer uBuffer = planeProxies[1].getBuffer();
        ByteBuffer vBuffer = planeProxies[2].getBuffer();

        int ySize = yBuffer.remaining();
        int uSize = uBuffer.remaining();
        int vSize = vBuffer.remaining();

        byte[] nv21 = new byte[ySize + uSize + vSize];

        //U and V are swapped
        yBuffer.get(nv21, 0, ySize);
        vBuffer.get(nv21, ySize, vSize);
        uBuffer.get(nv21, ySize + vSize, uSize);

        YuvImage yuvImage = new YuvImage(nv21, ImageFormat.NV21, imageProxy.getWidth(), imageProxy.getHeight(), null);
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        yuvImage.compressToJpeg(new Rect(0, 0, yuvImage.getWidth(), yuvImage.getHeight()), 100, out);

        byte[] imageBytes = out.toByteArray();
        return BitmapFactory.decodeByteArray(imageBytes, 0, imageBytes.length);
}

private void bindImageAnalysis(@NonNull ProcessCameraProvider cameraProvider) {
        Preview preview = new Preview.Builder().setTargetAspectRatio(AspectRatio.RATIO_16_9).build();
        preview.setSurfaceProvider(previewView.getSurfaceProvider());

        ImageAnalysis imageAnalysis =
                new ImageAnalysis.Builder()
                        .setTargetAspectRatio(AspectRatio.RATIO_16_9)
                        .setBackpressureStrategy(ImageAnalysis.STRATEGY_KEEP_ONLY_LATEST)
                        .setOutputImageFormat(ImageAnalysis.OUTPUT_IMAGE_FORMAT_YUV_420_888)
                        .build();

        imageAnalysis.setAnalyzer(ActivityCompat.getMainExecutor(this), imageProxy -> {
            try {
                Bitmap capturedImage = CameraXUtil.imageProxyToBitmap(imageProxy);
                String imageAnalysisFile = Common.saveImageToCache(capturedImage, getApplicationContext(), "test.jpg");
                Log.d("imageAnalysis", imageAnalysisFile);
            } catch (Exception e) {
                
            }
        });

        CameraSelector cameraSelector = new CameraSelector.Builder()
                .requireLensFacing(CameraSelector.LENS_FACING_BACK).build();
        cameraProvider.bindToLifecycle(this, cameraSelector, imageAnalysis, preview);
 }

the same thing happened to me in my image analysis use case, I changed the resolution of the image in the image analysis use case.
try changing the aspect ratio or resolution of an image or don't change the aspect ratio and image resolution at all.

I'm getting a distorted image as well. I am not trying to do any kind of analysis. I have a ton of code that works with bitmaps and I need to be able to use that code as is, but I am bringing in an ImageProxy object through React-Native and I just cannot figure out how to get it not to be distorted.

I am having the same problem. I created a plugin to Process Frames. In Android 12 I get distorted image, exact the same above.
