Why am I getting File not found error for ExifInterface with Android?

Question

I am using Firebase to store images for my android app. The images then appear in my app in a recycler view. This all works fine, however, certain images appear sideways. Specifically those taken with a Galaxy S7.

I know that I need to get the exif information from the images but when I try I get a file not found error what can I do?

private int getImageOrientation(String imagePath){
        int rotate = 0;
        try {
            File imageFile = new File(imagePath);

            ExifInterface exif = new ExifInterface(imageFile.getAbsolutePath());
            int orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);

            switch (orientation) {
                case ExifInterface.ORIENTATION_ROTATE_270:
                    rotate = 270;
                    break;
                case ExifInterface.ORIENTATION_ROTATE_180:
                    rotate = 180;
                    break;
                case ExifInterface.ORIENTATION_ROTATE_90:
                    rotate = 90;
                    break;
            }

        } catch (Exception e) {
            e.printStackTrace();
        }
        return rotate;
    }

I just need this to return how much the image is rotated but it always returns 0 since it throws a File not found expression. Any help would be greatly appreciated.

Download the file, then use the AndroidX edition of ExifInterface to examine it.

Or, if you will be showing these images in an ImageView , use an image-loading library like Glide or Picasso, which should take the EXIF orientation headers into account when displaying the images.

Answer 2

So the answer that I implemented works for me but I am not sure it will work in all cases. So when I am creating an image I set a boolean value to check if the height is more than the width. Then when I am loading the image in picasso I have:

Picasso.get()
                .load(imageURL_1)
                .fit()
                .rotate(post.isRotated()?0:90)
                .transform(new RoundedCornersTransformation(30,30))
                .into(imageView1);

Like I said this only works if the image is rotated counter clockwise 90 degrees. If there is a better fix I welcome your answers, but this is the best I can do without access to EXIF information.
