Code user input & output component of Tizen mobile app with existing UI (C, C++)

We require a developer experienced in C to complete the I/O component of a Tizen mobile app we are developing. The successful bidder will be responsible for the following small tasks: 1) Use appcontrol.h or similar to request input from the user, plus initiate or cancel that input request on command. 2) Retrieve & process data from json objects into the appropriate UI elements. and, if you want the extra work we might also be able to offer you these modules: 3) Loading and updating of config variables through Preference API. 4) TTS for a few UI elements Four small tasks, all of which are quite simple thanks to services available to implement them. All four are well documented in the API reference/coding guide, and Samsung provides sample code for all of them which can be easily adapted to our needs. In your proposal, please address each of the 4 tasks independently; i.e., quote timeframe and cost for each. The only two tasks guaranteed to be allocated to the successful bidder are the first two, however if you want to quote on items 3 & 4 we'd appreciate it. Look forward to hearing from you!
