Android mysql php问题

I have an application which gets some data from a remote database. I use PHP with the following code to connect to the data base.

mysql_connect($host,$username,$password) or die( "no connection");
@mysql_select_db($database) or die( "Unable to select database");

$query = $_REQUEST['query'];
$q=mysql_query($query);

while($e=mysql_fetch_assoc($q)) {
    $output[]=$e;
}
print(json_encode($output));

mysql_close();

I then connect via following java code

public void connect(ArrayList<NameValuePair> nameValuePairs) {
        result = "";
        InputStream is = null;

        String url = "http://'ipadress'/PhpProject1/EmptyPHP.php";

        //Get the content
        try {
            HttpClient httpClient = new DefaultHttpClient();
            HttpPost httpPost = new HttpPost(url);
            httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
            HttpResponse httpResponse = httpClient.execute(httpPost);
            HttpEntity httpEntity = httpResponse.getEntity();

            is = httpEntity.getContent();
        } catch (Exception e) {
            Log.e("Connect", "Error in http connection " + e.toString());
        }
        //Convert content toString
        try {
            BufferedReader reader = new BufferedReader(new InputStreamReader(is, HTTP.UTF_8), 8);
            StringBuilder sb = new StringBuilder();
            String line = null;

            while ((line = reader.readLine()) != null) {
                sb.append(line + "
");
            }
            is.close();
            result = sb.toString();
            //result = replaceString(sb.toString());
        } catch (Exception e) {
            Log.e("Connect", "Error converting result " + e.toString());
        }
    }

When i have done that I make a query through

public void query(String query){
        ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
        nameValuePairs.add(new BasicNameValuePair("query", query));
        connect(nameValuePairs);
    } 

While this works great with the emulator there is a problem when using it on the phone.

Anyone has a clue why this is?

Thank you in advance

Make sure to connect your real device to the your private network to actually be able to access that server.

Easiest option would be a WiFi network in the same subnet as the server. Otherwise your phone won't be able to access the network as it is not public.
