Display JPG images in an Adroid App

Create an Adroid Application to simple show thumbNails and JPG pictures from an archived file with a certain structure (see below, no compression involved) The archive does not need to employ compression/decompression. We use it as a simple container, the JPG files could be simply read as data buffers; encryption will be applied later The application will only have to show thumbnails of this pictures (by dynamically resizing the pictures), the full picture and buttons: SlideShow Random, SlideShow and Settings Upper row: Title 1 (Customizable) Second Row: Message Window Third Row: Category Thumbnails (should be taken from the main pictures folders, CAT_1_Thumb.jpg... [login to view URL]) Fourth Row: Text: "Pics in CAT X (Selected Category): MMMM" Left: Selected Category Pic 1.1... etc Picture 1 from category 1 is by default: [login to view URL] When pressed the image becomes partially full screen or full screen, as explained in the attached picture Requirements: Application should be somewhat customizable; Image files should be loaded locally, therefore, all pictures are in the .apk; no internet link, the app works offline Image files are called [login to view URL] (from first pic in cat1) to [login to view URL] (Picture Index MMMM from Category N) I should be able to modify <all> text variables (ex: #define Cat3 "CloseUps") A slideshow button to start a slideshow on files from a particular CATegory; always ask: Start from Pic 1.1 or continue from previously shown Slideshow pictures (settings customizable) EX: Never start a slideshow from a CAT II when CAT III is selected A Random Slideshow button also available; start with random pics: Show "Pic_?_?????.jpg" The single DB or archive of files should have a simple structure that could be modified later on: You make your own DB to test, following this structure: 4 bytes archive header (will be checked against a mask, say 0xFABACADA) 4 bytes - Total Count of Files 4 bytes - CheckSum of ARCHIVE (- the CheckSum value); could be md5 or any other simple method 2 bytes - Number of categories (CAT I, CAT II... CAT N etc) 4 bytes - CAT I Picture Count 4 bytes - CAT II Picture Count 4 bytes - CAT III Picture Count 4 bytes - CAT IV Picture Count ... 4 bytes - CAT N Picture Count Picture I from Cat I .... Picture N from Cat I .... Picture I from Cat N .... Picture N from Cat N Some markers in between or... a prescreening of archive when the app starts to know where to extract these from You can do your test with 1-2 JPGs in each category ex: Flowers - 2 pictures, Houses: 2 pictures, CARs: 2 pictures, Tools: 2 pictures, Buildings: 2 pictures GUI requirements: See atached pictures; Deliverables: I need an archive with all the source files and instructions: I expect to simply load the project, press "Build" and create a final APK. First, put mockup image files for proof of concept. CAT_1_Thumb.jpg... [login to view URL], then [login to view URL] to [login to view URL] (max 100000 files) could be any pictures in this mock-up application Files delivered should respect Google Play admission requirements (quality of work, size, time to load, etc) Android Version 4.X and up
