你可以尝试下面的代码：
try {JSONObject jsonObject = new JSONObject("{\"flag\":\"true\"}");jsonObject.toString();}catch (JSONException err){Log.d("Error", err.toString());}

您可以尝试使用Maven导入Jackson databind依赖：<dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-databind</artifactId><version>2.9.5</version></dependency>// 创建一个用于键值JSON的映射Map<String, String> obj = new HashMap();obj.put("flag", "true");ObjectMapper objectMapper = new ObjectMapper();// 将对象转换为字符串String output = objectMapper.writeValueAsString(obj);return output;
