Inside this directory will be created a subdirectory "images" to store all images and subdirectories required. The will be a initial configuration to store the address to download the SQLite database. On every start, the app will check for internet presence and for updates comparing remote info on a web service with local info on SQLite. Before proceding with updates, the app will ask the user before starting with downloads. A new SQLite db will be downloaded along with images and other files. After update-check phase, the app will open providing different data views. 1) CARD VIEW In this view the user will see items inside cards. The interface will show as many cards as possibile depending on the screen resolution, however everything must be equally divided and centered. Each card represent a single item in tblItems table. In every card must be shown: the image, the description, the cost and some other info. Sliding with finger, other set of cards will be shown until the end is reached. 2) DETAIL VIEW In detail view there will be a single card with more datas and bigger images zoomable. There can be more than one image, touching the image or sliding up/down change image from the current set. Sliding with the finger the user can move to next or previous item.
