android - Preferred method of working with logical objects -

-

i'm having array of objects represented json string coming api server. let's suppose have movie categories , actual movies belong each category:

[ {     "id": "1",     "name": "action",     "movies": [         {             "id": "1",             "name": "movie 1",             "description": "movie 1 description",             "other": "other..."         },         {             "id": "2",             "name": "movie 2",             "description": "movie 2 description",             "other": "other..."         }     ] }, {     "id": "2",     "name": "drama",     "movies": [         {             "id": "3",             "name": "movie 3",             "description": "movie 3 description",             "other": "other..."         },         {             "id": "4",             "name": "movie 4",             "description": "movie 4 description",             "other": "other..."         }     ] } ]

the users of android app need able browse through categories/movies. of following scenarios better regarding performance of code , optimal memory usage?
assume there many channels , categories.
1. parse json string once, create arraylists of category , movie objects each category later use them populating lists.
2. create parser few methods get_total_channels, get_channel, get_category parse contents of json string return me appropriate data populate lists.
3. other suggestion?
