Android simple slideshow app

General: Main app use, photo viewer and simple kids books. This an engine and not designed for a single release. I a have similar app for iPhone that you simply have to copy for android. I pay on time, provide exact instructions and even may pay a bonus if I get an extraordinary service. Developer requirements: Proven record of android apps development Great communication skills & support App features: 1. Display a list of JPG files (I manage that myself each time) 2. Play optional MP3 files (1 mp3 per slide, start automatically) 3. Text configuration file (JPG's , MP3, links...) like json file for iPhone. 4. Last slide is a web page (part of app) 5. Up to 3 URL links per slide (predefined location). 6. Zoom into the JPG (double click or button click for normal display) 7. Sound player buttons (stop, play, pause, mute-app level) 8. Navigation (next slide, previous, home (+back from home). 9. Page fold visual effect- controlled by finger for auto in button click. 10. Page fold sound effect (optional , defined in text configuration) 11. Next slide can be either from left or right (RTL/LTR) 12. preserve current page status - ser can switch to other app and get current page on return. i will provide link to iPhone app and video that demonstrate exactly how it looks for selected developers only.
