(Json is a very common data transmission format on mobile platforms. This example provides two methods for generating and parsing Json format files. The first is to read and write the json file through the JsonReader and JsonWriter objects. The sdk must be above 11. The second method uses JSONArray, JSONObject, JSONTokener and other objects to perform json read and write operations. The sdk is required to be above 9. This method can also be implemented in other versions of sdk by introducing jar packages. After starting the client, click the Inject json button (the first or third button) to generate a Json file (the orientation is cdjson. json in the root directory of the sdcard), and then click the Read json button (the second or fourth button). The JsonParserUtil2 class in the example corresponds to the first parsing method, and the JsonParserUtil class 2 corresponds to the second parsing method.
