pinterestからjsonを取得する際に問題が発生し、JSONArray部分で常にエラーが発生します。
コード
JSONArray bodyarray = null;
JSONParser jParser = new JSONParser();
JSONObject json = jParser.getJSONFromUrl(url);
Log.i("url",""+url);
Log.i("json",""+json);
try{
bodyarray = json.getJSONArray(TAG_body); <---- this is the error here "NullPointerException"
Log.i("JSON", ""+bodyarray);
}
JSONを受信しました

FacebookやTwitterからJSONを解析するときにこの問題は発生していません。これは、Pinterestリンクでのみ発生します。ピンタレストリンクでアレイを取得するにはどうすればよいですか？
これは使用しているパーサーです
public class JSONParser {
static InputStream is = null;
static JSONObject jObj = null;
static String json = "";
// constructor
public JSONParser() {
}
public JSONObject getJSONFromUrl(String url) {
// Making HTTP request
try {
// defaultHttpClient
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(
is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n"); //\n
}
is.close();
json = sb.toString();
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
// try parse the string to a JSON object
try {
jObj = new JSONObject(json);
} catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
}
// return JSON String
return jObj;
}
}
*これは、Log on json = sb.toStirng（）;のlogcatです。およびstr_final*
