not getting response response = httpclient.execute(request);

public class HTTPPoster {
    public static HttpResponse doPost(String url, JSONObject c) throws ClientProtocolException, IOException 
    {

        HttpClient httpclient = new DefaultHttpClient();
        HttpPost request = new HttpPost(url);

        HttpEntity entity;
        StringEntity s = new StringEntity(c.toString());
        s.setContentEncoding((Header) new BasicHeader(HTTP.DEFAULT_CONTENT_CHARSET, "application/json"));
        entity = s;
        request.setE开发者_StackOverflow社区ntity(entity);

        HttpResponse response;

        response = httpclient.execute(request);

        return response;
    }

}

This is the code but on response = http.client.execute(request) doesn't get response. I couldn't find why.

You should call the method asynchronously. Then it will work with the same code. Add these two lines of code to your project

StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
        StrictMode.setThreadPolicy(policy);

and make minimum sdk version to 9

You can check that if you are getting response from server or not by using following code :

HttpResponse response = httpClient1.execute(request);
                    Log.v("response code", response.getStatusLine()
                            .getStatusCode() + ""); 

If you get the value of response code as 200 then you are getting data from server and if the response code value >=300 then you have error at your server side.

First of all try to change the return type to String by doing these 2 steps

Change

public static HttpResponse doPost(String url, JSONObject c) throws ClientProtocolException, IOException 

to

public static String doPost(String url, JSONObject c) throws ClientProtocolException, IOException 

AND

Change

HttpResponse response; 

to

String response; 

---

Now check the response string? Is it still null?

This is a permission issue.

Add this line <uses-permission android:name="android.permission.INTERNET" /> to your manifest file and rebuild.
