Error with sending data from android to php

Question

below is the code snippet of my app trying to send the data to my php address.. It comes up with an error though. Ans when I check on my php server, it does not show up.. Here is the code snippet below:

 public void sendData() {
    String ip = getIpAddress();
 HttpClient httpclient = new DefaultHttpClient();
 HttpPost httppost = new HttpPost("http://mysamplephp.php?ip=" + ip + "&date=" + formattedDate + "&appname=amigosmexican"+ "&appid="+ android_id);
    try{
        List<BasicNameValuePair> deviceinfo = new ArrayList<BasicNameValuePair>(3);
         deviceinfo.add(new BasicNameValuePair("id", android_id));
         deviceinfo.add(new BasicNameValuePair("date", formattedDate));
         deviceinfo.add(new BasicNameValuePair("ip", ip));
         httppost.setEntity(new UrlEncodedFormEntity(deviceinfo));  

         HttpResponse response = httpclient.execute(httppost);

         InputStream is = response.getEntity().getContent();
         BufferedInputStream bis = new BufferedInputStream(is);
         ByteArrayBuffer baf = new ByteArrayBuffer(20);
         Log.i("postData", response.toString());
         int current = 0;

         while((current = bis.read()) != -1){
             baf.append((byte)current);
         }



    } catch (ClientProtocolException e) {

    } catch (IOException e) {
        Log.e("log_tag", "Error in http connection ",e);
         }
    }

}

The error is :

EDIT: snippet for getting external ip:

 public String getIpAddress() {
try {
for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {
    NetworkInterface intf = en.nextElement();
    for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {
        InetAddress inetAddress = enumIpAddr.nextElement();
        if (!inetAddress.isLoopbackAddress()) {
            return inetAddress.getHostAddress().toString();
        }
    }
}
} catch (SocketException ex) {
Log.e("LOG", ex.toString());
}
return null;
}

`ilyushin.ph` does not exist, which is clearly stated in the 2nd line of error output... — Marc B, Oct 12 '12 at 04:24
@Marc B - i see. assuming the URL is valid, my code is OK? or my code is correct? — omi0301, Oct 12 '12 at 04:27
Have you added permission for INTERNET in your AndroidManifest.xml file? — VendettaDroid, Oct 12 '12 at 04:55
Yes I have.. I think I figured out what the problem is.. The URL is valid. its just that my emulator cant connect to the internet. I tried it on my phone.. However, I think I am not getting the external IP address. I need the external IP address. Please see edit above . that is my snippet on how i get the external IP. — omi0301, Oct 12 '12 at 05:08

when you are passing parameters in List params then no need to write them in url,

try your code this way,

public void sendData() {
String ip = getIpAddress();
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://mysamplephp.php");
try{
    List<BasicNameValuePair> deviceinfo = new ArrayList<BasicNameValuePair>(3);
     deviceinfo.add(new BasicNameValuePair("id", android_id));
     deviceinfo.add(new BasicNameValuePair("date", formattedDate));
     deviceinfo.add(new BasicNameValuePair("ip", ip));
     httppost.setEntity(new UrlEncodedFormEntity(deviceinfo));  

     HttpResponse response = httpclient.execute(httppost);

     InputStream is = response.getEntity().getContent();
     BufferedInputStream bis = new BufferedInputStream(is);
     ByteArrayBuffer baf = new ByteArrayBuffer(20);
     Log.i("postData", response.toString());
     int current = 0;

     while((current = bis.read()) != -1){
         baf.append((byte)current);
     }



} catch (ClientProtocolException e) {

} catch (IOException e) {
    Log.e("log_tag", "Error in http connection ",e);
     }
}

Try this, it will work. For more details see this demo code

thanks for your answer. BUt what if i want to use this http://xxxxxxxxxxxxxxxxxxxxxxx.php?ip=" + ip + "&date=" + formattedDate + "&appname=amigosmexican"+ "&appid="+ android_id? SO i no longer need to make a list? – omi0301 Oct 12 '12 at 05:44
i think its with the ip address i am trying to get. do you have any way of getting the external ip? because my external ip is 116.x.x.x. However, on my php server, it shows 192.x.x.x. – omi0301 Oct 12 '12 at 05:52
if you are using parameters within url then no need to add List params – Rahul Upadhyay Oct 12 '12 at 06:04
and which ip address you want to get? Device running on or other? refer [http://stackoverflow.com/questions/6064510/how-to-get-ip-address-of-the-device] this – Rahul Upadhyay Oct 12 '12 at 06:04
the external ip address of the device – omi0301 Oct 12 '12 at 06:09
