Show Image in Android as a result of REST API Respone Header

Question

My REST API is returning an image in the header ('Content-Type', 'image/png'). The image is stored as binary in SQL Server (data type: picture, stored in binary format). API's response is perfect as I have checked in Postman.
I want to display that image in Android. (I am using volley for Network requests.)
Any thoughts?
Thank you in advance.

EDIT1
Here is my slim REST API route that returns the image.

//get image
 $app->get('/image', function ($request, $response) {
$conn = new PDO('sqlsrv:server =localhost; Database = dbName', 'dbUser', 'dbPass');
$sql = "SELECT Picture 
        FROM Table
        WHERE Primary_Key = 'abc'";

$statement = $conn->prepare($sql);
$statement->execute();
$row = $statement->fetch(PDO::FETCH_ASSOC);
return $response->withHeader('Content-Type', 'image/png')->write($row['Picture']);}

EDIT2
Here is my API get request call using volley at Android end. This code resides in a Fragment. url is a String variable, profileImage is an ImageView where I want to use that fetched image.

url= getString(R.string.api_url) + "image";
    request = new StringRequest(GET, url, new Response.Listener<String>() {
        @Override
        public void onResponse(String response) {

            byte[] byteArray = response.getBytes();
            Bitmap bitmap = 
            BitmapFactory.decodeByteArray(byteArray,0,byteArray.length);
            profileImage.setImageBitmap(bitmap);
        } //onErrorResponse
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            error.printStackTrace();
        }
    }) {
    };
    queue = Volley.newRequestQueue(getActivity());
    queue.add(request);

`My REST API is returning an image in the header ('Content-Type', 'image/png'). `. No. That is a content type. A string. Some characters. — blackapps, Apr 18 '20 at 07:30
My GET API call(http://localhost/api/image) is returning the image. I can't get this image in Android via volley — Rizwan Abbasi, Apr 18 '20 at 07:38
@blackapps and Android_id : I am working on the question to put some code. I have just edited the question and inserted code for the API. Thank you. — Rizwan Abbasi, Apr 18 '20 at 08:26
@blackapps I have added code for both API end and Android end. — Rizwan Abbasi, Apr 18 '20 at 08:38
`//below line gives error on response,`. Yes. And already at compile time as response is a string and not a stream. — blackapps, Apr 18 '20 at 09:23
I know that is a string. How should I populate my ImageView? — Rizwan Abbasi, Apr 18 '20 at 09:27
I have updated onResponse() code. Now I can't see the image in ImageView. — Rizwan Abbasi, Apr 18 '20 at 10:33
I think First you will have to decode the string i.e,the response something like byte [] byteArray = Base64.decode(response,Base64.DEFAULT); — Android_id, Apr 18 '20 at 11:08
java.lang.IllegalArgumentException: bad base-64 at android.util.Base64.decode(Base64.java:1 Also, if I try to store the hardcoded binary of the image in the byte[] , it gives me error. Integer Number too large. It has more than 65k characters. — Rizwan Abbasi, Apr 18 '20 at 11:18
Here is the image that is stored in SQL Server in Picture format. https://rizwanabbasi.com/image.txt — Rizwan Abbasi, Apr 18 '20 at 12:18

After doing a lot of effort, I came to conclusion that this question is possible duplicate of How to download an Image by using Volley?

I replaced the value of url = "https://i.stack.imgur.com/dbujt.png"; with my API GET request and result is perfectly as desired.

Here is the code from that question thread.

ImageView mImageView;
String url = "https://i.stack.imgur.com/dbujt.png";
mImageView = (ImageView) findViewById(R.id.myImage);
...

// Retrieves an image specified by the URL, displays it in the UI.
ImageRequest request = new ImageRequest(url,
new Response.Listener<Bitmap>() {
    @Override
    public void onResponse(Bitmap bitmap) {
        mImageView.setImageBitmap(bitmap);
    }
}, 0, 0, null,
new Response.ErrorListener() {
    public void onErrorResponse(VolleyError error) {
        mImageView.setImageResource(R.drawable.image_load_error);
    }
});
// Access the RequestQueue through your singleton class.
MySingleton.getInstance(this).addToRequestQueue(request);

Thank you all for helping.
