Export Json to SQLite example
This code convert Json string from file to SQLite database
How to use
Create sqlite convertor
SQLiteDB sqlite = new SQLiteDB(); Create gson parser
Gson gson = new Gson(); Load Json string from disk
String jStr = LoadAssetFile("airports.json"); Parse Json objects in your Java classes
Airports airoports = gson.fromJson(jStr, Airports.class); Convert your Classes to SQLite Database
sqlite.createDb("airports.db", airoports.getClass().getSimpleName() .toLowerCase(), airoports.getAirports(), Airport.class.getDeclaredFields()); Parametrs
- SQLite Database Name
- Table name
- List Objects
- Fields of Class. This fields will be columns name in table
Example
