Images rotated automatically

[Bilal512]

Images selected from camera roll are rotated 180 degree automatically and there is no way to fix that.

Replace loadBitmap method and Add rotateBitmap method in SimplePhotoData.java file

private Bitmap loadBitmap(String uri) {
        Bitmap bitmap = null;
        if (uri.startsWith("drawable://")) {
            String idStr = uri.substring("drawable://".length());
            int id = Integer.parseInt(idStr);
            bitmap = BitmapFactory.decodeResource(mContext.getResources(), id);
        } else if (uri.startsWith("file://")) {
            String path = uri.substring("file://".length());
            bitmap = BitmapFactory.decodeFile(path);
        } else if (uri.startsWith("http")) {
            InputStream is = null;
            try {
                URL url = new URL(uri);
                HttpURLConnection connection = (HttpURLConnection) url.openConnection();
                is = connection.getInputStream();
                bitmap = BitmapFactory.decodeStream(is);
