Spotify Android SDK搜索曲目号码

我目前已连接到Spotify sdk，我目前正在寻找能够让用户搜索曲目并返回曲目编号。我跟着sdk指南来跟踪歌曲，并将响应作为JSON响应得到，但是当我尝试在android中根据字符串响应创建JSONArray时，它告诉我无法创建JSONArray。我目前得到的回应是这样的Spotify Android SDK搜索曲目号码

和我的Android代码看起来像这样

try { 
      response = httpClient.execute(httpPost); 
      responseBody = EntityUtils.toString(response.getEntity()); 
      try { 
       jsonArray = new JSONArray(responseBody); 
      } catch (JSONException e) { 
       e.printStackTrace(); 
      }

你需要首先检索JSONObject而不是JSONArray然后去JSONArray“跟踪” – Nisarg

执行此

JSONObject jObj; 
try { 
     jObj = new JSONObject(responseBody); 
    } catch (JSONException e) { 
     e.printStackTrace(); 
    }
