Today we will introduce json data parsing. We use JSONObject and JSONArray in Android to parse json data. For more information, see android Developers. String strJson = "{" students ": [{" name ":" Jack "," age ": 12 },{" name ":" Vista "," age ": 23 },{ "name": "Kaka", "age": 22 },{ "name": "Hony", "age": 31}]} ";Try

SQLite lightweight database is mainly used for embedded systems. It only occupies hundreds of K of system resources and has the following features: lightweight: you only need a dynamic library to enjoy all the functions, in addition, the dynamic library size is also very small and independent: the Core Engine does not need to rely on third-party software isolation: All database information (tables, views, triggers) is stored in the same file cross-platform: supports most operating systems, you c
