I'm about to make an application for ipad that has the following specifications:
- download JSON (or xml) from server
- download short audiofiles from server (locations are in the JSON from above)
- save these to the iPad for offline use.
- based on these files the user gets to do some exercises
- user progress/results need to be saved to the device so they can continue where they left off the next time they launch the app.
My question: Can this be done with only html/css/jquery Phonegap? Or should I go native and make this all in Objective-C? Or can I combine phonegap and Objective-C?
Now I'd like to know how I can save a json file on the device for offline use. Also I'd like to know how to download audio (or images or whatever) and save those to the device.
