尝试在三星 gio（运行 2.3.6）上解析一些 JSON 时遇到一个奇怪的异常，我已经在 xperia neo（运行 4.0）上尝试过它运行良好，我也尝试过不同的 JSON 它适用于两者设备，我已经验证了 JSON 并且它是有效的！我提供代码、json 文件和 logcat，不胜感激。

解析器

public static JSONObject getJSONObject(String url) throws ClientProtocolException, IOException, JSONException
{
    DefaultHttpClient httpclient = new DefaultHttpClient(new BasicHttpParams());
    HttpPost httppost = new HttpPost(url);
    httppost.setHeader("Content-type", "application/json");
    InputStream inputStream = null;
    HttpResponse response;
    response = httpclient.execute(httppost);
    HttpEntity entity = response.getEntity();
    inputStream = entity.getContent();
    //buildJSONString( inputStream );
    String s = buildJSONString( inputStream );
    Log.v("", s); // note that s is printed along all json files and all devices
    JSONObject jObj = new JSONObject( s );
    Log.v("", jObj +""); // it doesnt print on samsung, prints on xperia
    return jObj ;
} 
private static String buildJSONString( InputStream inputStream ) throws IOException
    {
        BufferedReader reader;
        StringBuilder stringBuilder=null;
        reader = new BufferedReader(new InputStreamReader(inputStream,"UTF-8"), 8);
        stringBuilder = new StringBuilder();
        String line = null;
        while ((line = reader.readLine()) != null)
            stringBuilder.append(line + "\n");
        if (inputStream != null)
            inputStream.close();
        return stringBuilder.toString();
    }

工作的json

{
    "song_list": [
        {
            "id": "4",
            "title_en": "Aces High",
            "artist_en": "IRON MAIDEN",
            "thumb_url": "http://192.168.0.81:8080/content/iron_maiden.jpg",
            "media_url": "http://192.168.0.81:8080/content/iron_maiden.mp3",
            "preview_url": "blabla",
            "num_download": "2846",
            "price": "0.50",
            "rating" : "4"
        },
        {
            "id": "8",
            "title_en": "Wasted Years",
            "artist_en": "IRON MAIDEN",
            "thumb_url": "http://192.168.0.81:8080/content/iron_maiden.jpg",
            "media_url": "http://192.168.0.81:8080/content/iron_maiden.mp3",
            "preview_url": "blabla",
            "num_download": "1984",
            "price": "0.50",
            "rating" : "4"
        }
    ]
}

不工作的json

{
    "artist_list": [
        {
            "id": "1",
            "artist_en": "MOTORHEAD",
            "artist_ar": "موتورهيد",
            "thumb_url": "http://192.168.0.81:8080/content/motorhead.jpg",
            "num_download": "2846"
        },
        {
            "id": "2",
            "artist_en": "WHITESNAKE",
            "artist_ar": "وايتسنيك",
            "thumb_url": "http://192.168.0.81:8080/content/whitesnake.jpg",
            "num_download": "1984"
        }
    ]
}

服务器命中

@Override
protected String doInBackground(String... arg0)
{
    try
    {   jObject = JSONParser.getJSONObject(url);    }
    catch (Exception e)
    {   cancel(true);   Log.v("", "failed");    }
    return null;
}

尝试这个

response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
String s = EntityUtils.toString(entity, HTTP.UTF_8);

来自Android Java UTF-8 HttpClient 问题

您将必须导入 apache 依赖项。
