How to save a image Jpge from surfaceView using Camera?

I need to get information from php web service, but when I do HttpPost in android The application breaks jusrt in HttpResponse response = httpclient.execute(httppost);

this is my Android code

public String getHttp(){
    String jsonResult ="";
    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("http://ift.tt/1OsSjeZ");
    try {
        HttpResponse response = httpclient.execute(httppost);
          jsonResult = convertStreamtoString(
                response.getEntity().getContent()).toString();
    }
    catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    return jsonResult;
}

private String convertStreamtoString(InputStream resultado) throws IOException{
    if(resultado != null){
        StringBuilder sb = new StringBuilder();
        String con = "";
        try{
            BufferedReader br = new BufferedReader(
                    new InputStreamReader(resultado, "UTF-8"));

            while((con = br.readLine())!= null){
                sb.append(con).append("'n");
            }

        }finally{
            resultado.close();
        }
        return sb.toString();
    }
    else{
        return "";
    }
}

and this is my PHP code

<?php 
 include ('conex.php');
       $result = mysql_query("Select nombre FROM escuela") or die("No se realizo");
       $json = array();
        if(mysql_num_rows($result)){
              while ($row = mysql_fetch_assoc($result)) {
                   $json[]= $row;
               }
        }
        echo json_encode($json);
?>
