android jsonデータ取得

jsonデータをstringオブジェクトに変換

public static String getContent(String url) {
    StringBuilder sb = new StringBuilder();
    try {
        HttpClient client = new DefaultHttpClient();
        HttpParams httpParams = client.getParams();
        HttpConnectionParams.setConnectionTimeout(httpParams, 3 * 1000);
        HttpConnectionParams.setSoTimeout(httpParams, 5000);
        HttpResponse response = client.execute(new HttpGet(url));
        HttpEntity entity = response.getEntity();
        if (entity != null) {
            BufferedReader reader = new BufferedReader(
                    new InputStreamReader(entity.getContent(), "UTF-8"),
                    8192);
            String line = null;
            while ((line = reader.readLine()) != null) {
                sb.append(line + "
");
            }
            reader.close();
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
    return sb.toString();
}
