Androidでhttpポストを使用してWebサービスからデータを取得する方法があります。
私のコードは、
public class PropertyRequestService {
static String result;
PropertiesList localProperty = new PropertiesList();
List<PropertiesList> Properties;
List<PropertiesList> PropertiesRS;
public List<PropertiesList> getAllPropertiesStuff() {
try {
HttpClient client = new DefaultHttpClient();
HttpPost httppost = new HttpPost(
"Here Given Webservice URL");
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs
.add(new BasicNameValuePair("string", "value"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = client.execute(httppost);
HttpEntity entity = response.getEntity();
if (entity != null) {
InputStream instream = entity.getContent();
String response1= convertStreamToString(instream);
// Closing the input stream will trigger connection release
instream.close();
//result = EntityUtils.toString(entity);
Log.i("RESPONSE=", response1);
JSONObject json = new JSONObject(response1);
PropertiesRS.add(SplitResult(json));
}
} catch (Exception e1) {
e1.printStackTrace();
}
return PropertiesRS;
}
public static String convertStreamToString(InputStream instream) {
BufferedReader reader = new BufferedReader(new InputStreamReader(instream));
StringBuilder sb = new StringBuilder();
String line = null;
try {
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
instream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return sb.toString();
}
これはlogcatです。

この例外が発生する理由がわかりません。
クライアント要件の制限により、json 形式でデータを送信するようにアプリケーションを変更できません。
Androidで応答をjsonオブジェクトに変換するには? これは私の貴重な時間を奪い、先に進めません。私はここで立ち往生しています。
アイデアや提案をお願いします！
前もって感謝します..
