Android httppost network violation

Question

I have a problem with my android app. I mean I'm using the code from one of tuts in the internet, looks like below

public static String sendLocation(String s) {
    // Create a new HttpClient and Post Header
    //HttpParams params = new BasicHttpParams();
    //params.setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);
    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("http://google.com/read.php");
    //String d = "ok";

    try {
        // Add your data
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
        nameValuePairs.add(new BasicNameValuePair("user", "mobile"));
        nameValuePairs.add(new BasicNameValuePair("location", s));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        // Execute HTTP Post Request
        HttpResponse response = httpclient.execute(httppost);

    } catch (ClientProtocolException e) {
      //  d = "CPE";
    } catch (IOException e) {
       // d = "E";
    }
    return "send";
}

}`

And the problem/bug appeared when the app try to send data to the remote server (the line below)

// Execute HTTP Post Request HttpResponse response = httpclient.execute(httppost);

I also use the StrictMode and after that everything works, the logs shows network violation

11-08 22:34:40.020: D/StrictMode(939): StrictMode policy violation; ~duration=359 ms: android.os.StrictMode$StrictModeNetworkViolation: policy=31 violation=4

I included in the manifest file appropriate permission

<uses-permission 
    android:name="android.permission.ACCESS_FINE_LOCATION" />

Do you have any idea what should I do to run my app (actually send data via post to the server) without StrictMode?

The problem is that you are trying to do network calls on the main UI thread. Only use those types of methods in a separate thread.

A good example of that is here.

See [this question](http://stackoverflow.com/a/10955043/2050) on how to find about the policy and the violation. – Eric Platon Jun 20 '14 at 08:17
