How to draw a processed frame back to the screen in Camera2 api

Question

I'm attempting to grab frames of video from the Camera2 API in Android Studio and do some simple image processing on each frame.

The issue I am having is in drawing the processed frame back to the screen.

I am using code from the camera2raw example.

I'm modifying the pixel value in the buffer which stores all the frames.

Right now I'm just adding a constant value to each pixel to see if the image on the screen is modified or not.

The image on the screen is not changed by adding even a very large value to each pixel.

Therefore, I'm fairly confident I'm not writing the modified pixel values back to the screen.

Here is a code snippets from relevant portions of the program:

ImageReader.OnImageAvailableListener imageAvailableListener = new ImageReader.OnImageAvailableListener() {
    @Override
    public void onImageAvailable(ImageReader reader) {
        Image image = null;
        try {
            image = reader.acquireLatestImage();

            ByteBuffer Y = image.getPlanes()[0].getBuffer();
            ByteBuffer U = image.getPlanes()[1].getBuffer();
            ByteBuffer V = image.getPlanes()[2].getBuffer();

            int Yb = Y.remaining();
            int Ub = U.remaining();
            int Vb = V.remaining();

            byte[] data = new byte[Yb + Ub + Vb ];
            //your data length should be this byte array length.

            for (int i = 0; i < 512; i++)
            {
                for (int j = 0; j < 512; j++)
                {
                    int idx = i * 512 + j;
                    data[idx] += 255;
                }
            }
            // Screen should now show some distortion.
            Y.get(data, 0, Yb);
            U.get(data, Yb, Ub);
            V.get(data, Yb+ Ub, Vb);

        } catch (Exception ee) {
        } finally {
            if (image != null)
                image.close();
        }
    }

    //void save(byte[] bytes) {
        File file12 = getOutputMediaFile();
        OutputStream outputStream = null;
        try {
            outputStream = new FileOutputStream(file12);
            outputStream.write(bytes);
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                if (outputStream != null)
                    outputStream.close();
            } catch (Exception e) {
            }
        }
   // }
};

Please let me know if providing further explanation or sections of code will help make my question more clear.

Can someone please tell me how I write back to the screen the modified frame?

I have also tried doing this:

// Convert bytes data into a Bitmap
Bitmap bmp = BitmapFactory.decodeByteArray(data, 0, data.length);
ImageView imageView = new ImageView(MainActivity.this);
// Set the Bitmap data to the ImageView
imageView.setImageBitmap(bmp);
// Get the Root View of the layout
ViewGroup layout = (ViewGroup) findViewById(android.R.id.content);
// Add the ImageView to the Layout
layout.addView(imageView);

There are posts related to this issue but none has an exact solution. Can anyone provide me with a link to detailed step by step instructions of how to achieve what I described?
