SOLVED: No faces found on image, solution by @aznxed

If faces are not detected, try this solution by @aznxed. The issue is that face are only detected when you take a picture in landscape mode which makes the usability of the app - and the code we learn - very limited, outright broken. This solution rotates the portrait images so that they are usable and face detection works as intended.

    Try this in addition to line 73 in BitmapUtils.java, tested in portrait mode on Google Pixel 2

    Matrix matrix = new Matrix();
    matrix.postRotate(-90);

    Bitmap bitmapOrg = BitmapFactory.decodeFile(imagePath);
    Bitmap scaledBitmap = Bitmap.createScaledBitmap(bitmapOrg, bitmapOrg.getWidth(), bitmapOrg.getHeight(), true);
    Bitmap rotatedBitmap = Bitmap.createBitmap(scaledBitmap, 0, 0, scaledBitmap.getWidth(), scaledBitmap.getHeight(), matrix, true);

    return rotatedBitmap;
