我正在尝试在Android应用程序中使用gson解析一个json对象，测试在模拟器中非常顺利地通过了，当我使用实际设备时，问题开始了我得到如下异常

请提出解决方案，我使用的是 gson 1.4 版本。我使用的代码是

            URLsource = new URL("http://.........);
      in = new BufferedReader(new UnicodeReader(URLsource.openStream(), "UTF-8"));
       jse = new JsonParser().parse(in);
    in.close(); 
            JsonArray info = jse.getAsJsonObject().getAsJsonArray("info");

浏览器中 url 的 o/p 是

    {"info":[{"restaurant_id":"","name":"Vie de France","campus_id":"","address":"600 Maryland Ave SW","city":"WASHINGTON","state":"DC","neighborhood":"","neighborhood_urlname":"","zipcode":"20024","average_entree":"6.29","chain_id":"994","phone":"(202) 554-7870","is_voicestar":"0","menu_type":"1","url":"","logo":"","details":"","latitude":"38.886877","longitude":"-77.019913","properties":"rmwa","reviews":"y","yelp_phone":"2025547870","reservation_id":"","reservation_url":"","price":"","cross_street":"","public_transit":"","restaurant_description":"","payment_methods":"","hours":"","next_open":"","restaurant_status":"","is_preorder":"","citysearch_hours":" ","minimum_order":"","minimum_order_2":"","delivery_rate":"","delivery_time":"","delivery_info":"","misc_info":"","delivery_charge":"","delivery_charge_2":"","is_pickup":"","is_delivery":"","minimum_tip_amount":"","minimum_tip_percent":"","restaurant_account_id":"","urlname":"\/dc\/washington\/239256-vie-de-france\/","facebook_fan_page":"","twitter_page":"","is_dz":"0","loyalty":"","delivery_hours":""}],"cuisines":[{"mastercuisineid":"143","cuisine":"American","urlname":"american"},{"mastercuisineid":"90","cuisine":"Bakery & Pastries","urlname":"bakery-pastries"},{"mastercuisineid":"57","cuisine":"French","urlname":"french"}]}

您似乎正在尝试将 HTTP 解析为 JSON。HTTP在任何 JSON 实体之前都有一个状态行和标头。

If your JSON is on a server and you access it through an HTTP request, you need to parse only the content, not the whole file with the headers.
Try doing an HTTP client, use getResponse.getEntity or getResponse.getContent, and then your parser on one of these.
