Be able to upgrade/update our current app with extra options/features. Your initial duties include: 1. Fix/solve "force close", "freeze", "crash" errors and other annoying unexpected issues reported by users happening almost on daily basis. 2. Improve device compatibility with all Android versions (1.6 and up) 3. Optimize coding structures to remove unnecessary loading time (more speed), reduce overall file size and improve efficiency to the max. Your next duties include: 1. Enhance search functionalities. 2. Add ability to handle crash report. 2. Add save to SD option. 3. Add Email and social plugin 4. Add voice recognition (if feasible - without slowing app down) Due to this app fetching lots of queried data from the server (mainly search), you must be highly knowledgeable for efficiently being able to handle data transfer between the server and app without causing force closes, crashes, freezes, and minimize delays. If you have experience in highly sophisticated search type app done previously, its def. a plus++. If you're the right person, this is an upgrade work to long term contract opportunity (debug, update works).
