The first method is to read and write json files through JsonReader and JsonWriter. the sdk must be later than 11.
Second, perform json read/write operations on objects such as JSONArray, JSONObject, and JSONTokener. the sdk must be later than 9. This method can also be implemented in other sdk versions by introducing jar packages.
After the client is started, click the write json button (1st or 3 buttons) to generate a Json file (location: cdjson under the sdcard root directory. json), and then click the read json button (2nd or 4 buttons ).
