Simple android app to parse json data

This is a growing Android application project with initial app to parse data from a simple json files. Lets consider our JSON file to be like this: [{ "Toyota": { "model": [{ "description": "RAV 4 is a great car", "price": 23000 }, { "description": "RAV 4 hybrid is a great car", "price": 29000 }, { "description": "RAV 4 manual is a great car", "price": 21000 } ], "shortdesc": "Good for family!" }, "Mazda": { "model": [{ "description": "Mazda is a great car", "price": 22000 }, { "description": "Mazda2 hybrid is a great car", "price": 24000 }, { "description": "Mazda3 manual is a great car", "price": 17000 } ], "shortdesc": "Good for family and sports!" }, "Subaru": { "model": [{ "description": "Subaru is a great car", "price": 20500 }, { "description": "Subaru hybrid is a great car", "price": 33000 }, { "description": "Subaru manual is a great car", "price": 25000 } ], "shortdesc": "Good for sports!" } }] Add this JSON into a file([login to view URL]) and call from a web url... example: [login to view URL] DO NOT upload file in android project... JUST CALL IT FORM A URL... this is how I want it to happen: Screen 1: Initial Android Screen: (list view) ---------------------------------- TITLE: Select Car Toyota Good for family! Mazda Good for family and sports! Subaru Good for sports! Screen 2: After tapping on one of the CAR NAME.. Android Screen: (list view) ---------------------------------- TITLE: Select Model RAV 4 is a great car 23000 RAV 4 hybrid is a great car 29000 RAV 4 manual is a great car 21000 Screen 3: After tapping on one of the CAR MODEL.. Android Screen: (list view) ---------------------------------- TITLE: Verify Toyota RAV 4 is a great car ------ Note that the data is being extracted via json file for above screens ------ So basically there are 3 screens, that we will navigate after each selection. The screen navigation is based upon the same JSON files... so make sure to keep track of the JSON structure. Please NOTE: * do not use any third party library. I WILL REJECT YOUR PROJECT. * use simple JAVA methods. No need to make it advanced. I just need it in simple steps * create Activity for each screen * make sure that you follow the activity lifecycle properly * put a home button to go back to the initial screen and reset the android life cycle.. do not make it crash create a new lifecycle without ending the first one..
