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;
英文:
You can try using Maven Jackson databind dependency
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.9.5</version>
</dependency>
// Create a map for your key value json
Map<String,String> obj = new HashMap();
obj.put("flag","true");
ObjectMapper objectMapper = new ObjectMapper();
// Convert object into string
String output = objectMapper.writeValueAsString(obj);
return output;
