How to resize bitmap before sending it with retrofit2 to avoid large size exception

I asked this question so many times and nobody answers me I don not know why, and everybody ignored it, please I need help with bitmaps, I have tried so many ways that I saw on the Internet but none solved my problem. I want to compress an image which was selected from gallery before sending it with retrofit. I saw so many ways the decode the image into string or byteArray ... etc but none worked with me. Please help me with this, my app is almost done except this issue.

I tried to convert the bitmap to a FILE: Didn't work. I tried to convert the bitmap to a BYTEARRAY: Didn't work. I tried to convert the bitmap to a STRING : Didn't work.

  public byte[] getFileDataFromDrawable(Bitmap bitmap) {
        ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.PNG, 80, byteArrayOutputStream);
        return byteArrayOutputStream.toByteArray();
    }

I expect to shrink the size of the image before sending it to the server using retrofit2

        });
    }

You can resize your bitmap with this code

private static Bitmap getResizedBitmap(Bitmap image, int IMAGE_MAX_SIZE) {

    int width = image.getWidth();
    int height = image.getHeight();

    float bitmapRatio = (float) width / (float) height;
    if (bitmapRatio > 1) {
        width = IMAGE_MAX_SIZE;
        height = (int) (width / bitmapRatio);
    } else {
        height = IMAGE_MAX_SIZE;
        width = (int) (height * bitmapRatio);
    }

    return Bitmap.createScaledBitmap(image, width, height, true);
}

use a third party library to compress the file. I used to work with this one https://github.com/Sunzxyong/Tiny , and I got good results.
