I got it after along search , but from a J2ME code.

blocks|key|1106118|text|尝试在您的响应上使用EntityUtil：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1106119|String+responseBody+=+EntityUtils.toString(response.getEntity());|code-block|syntax|javascript|1106120|entityMap^0|A|A|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|P|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|Q|8|@]|D|@]|E|$]]]|L|$]]

Try to use the <code>EntityUtil</code> on your response:

<pre><code>String responseBody = EntityUtils.toString(response.getEntity());
</code></pre>

blocks|key|1106143|text|您可以使用ResponseHandler调用execute方法。下面是一个例子：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1106144|ResponseHandler<String>+responseHandler+=+new+BasicResponseHandler();
String+response+=+httpClient.execute(httppost,+responseHandler);|code-block|syntax|javascript|1106145|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

You can call execute method with a ResponseHandler. Here's an example:

<pre><code>ResponseHandler&lt;String&gt; responseHandler = new BasicResponseHandler();
String response = httpClient.execute(httppost, responseHandler);
</code></pre>

blocks|key|1106167|text|试试这个，它看起来是最紧凑的。尽管在现实世界中，您需要使用异步请求，以便设备在检索请求的页面时不会挂起。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1106168|http://www.softwarepassion.com/android-series-get-post-and-multipart-post-requests/|offset|length|1106169|entityMap|0|LINK|mutability|MUTABLE|url^0|0|0|2B|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|N|8|@]|9|@$D|O|E|P|1|Q]]|A|$]]|$1|F|3|-4|5|6|7|R|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|C]]]]

Try this, it seems to be the most compact. Although in the real world, you'd need to use an asynchronous request so the device won't hang while the requested page is being retrieved.

You should try using HttpGet instead of HttpPost. I had a similar problem and that solved it.

I have been trying long to send an HttpPost request and retrieve response but even though I was able to make a connection I don't yet get how to get the string message which is returned by the request-response

<pre><code> HttpClient httpclient = new DefaultHttpClient();
 HttpPost httppost = new HttpPost("http://www.myurl.com/app/page.php");
 // Add your data 
 List &lt; NameValuePair &gt; nameValuePairs = new ArrayList &lt; NameValuePair &gt; (5);
 nameValuePairs.add(new BasicNameValuePair("type", "20"));
 nameValuePairs.add(new BasicNameValuePair("mob", "919895865899"));
 nameValuePairs.add(new BasicNameValuePair("pack", "0"));
 nameValuePairs.add(new BasicNameValuePair("exchk", "1"));

 try {
 httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
 Log.d("myapp", "works till here. 2");
 try {
 HttpResponse response = httpclient.execute(httppost);
 Log.d("myapp", "response " + response.getEntity());
 } catch (ClientProtocolException e) {
 e.printStackTrace();
 } catch (IOException e) {
 e.printStackTrace();
 }
 } catch (UnsupportedEncodingException e) {
 e.printStackTrace();
 } 
</code></pre>

I'm sorry, I sound very naive because I'm new to java. Please help me.
