背景

想用Android整一个聊天机器人，测试一下功能。

参考文档

在这里插入图片描述

申请DeepSeek API KEY（略）

代码

参考文档中的代码已经基本满足要求，主要是返回结果为JSON格式没有解析，内容比较乱，加一些简单的解析即可。

package com.example.myapplication;

public class MainActivity extends AppCompatActivity {

    private static final String API_KEY = "KEY"; // 替换为你的 DeepSeek API 密钥
    private DeepSeekApiService apiService;
    /*Input: msg 发送给AI的信息*/
    /*返回AI的对话结果。注意：DeepSEEK 服务经常没有相应*/

    String DeepSeekApi(String msg)
    {
