            this.transferred += len;

            this.transferred++;
            this.listener.transferred(this.transferred);
        }
    }
}

This is config

package com.camerafileupload;

public class Config {
     public static final String FILE_UPLOAD_URL = "url.com/android_upload/file_upload.php";

        // Directory name to store captured images and videos
        public static final String IMAGE_DIRECTORY_NAME = "android_upload";

Answer 1
