How do I Post Data in Android?

Question

I've found this topic for PostData using http. but it doesn't work.

What's wrong?

I also requested Android.permission.INTERNET in the manifest.

    public void postData() {
    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("http:/mysite.com/postTest.php");
    try {
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
        nameValuePairs.add(new BasicNameValuePair("pw", "12456"));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        // Execute HTTP Post Request
        HttpResponse response = httpclient.execute(httppost);
        tv.setText(response.toString());
    } catch (ClientProtocolException e) {
        //
    } catch (IOException e) {
        //
    }
}

Edit

My application will be terminated with this message : Unfortunately PostDataProject has stopped.

"it doesn't work" - no exception, no description, no idea what the problem is. — Lukas Knuth, Apr 07 '12 at 10:17

try this:

HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = responce.getEntity();
// convert stream to String 
BufferedReader buf = new BufferedReader(new InputStreamReader(entity.getContent()));
StringBuilder sb1 = new StringBuilder();
String line = null;
while ((line = buf.readLine()) != null) {
sb1.append(line);
}
tv.setText(sb1.toString());

and u can direclty set to textview if data is only for textvew or small:

tv.setText(EntityUtils.toString(response.getEntity()));

and use this:

HttpPost httppost = new HttpPost("http://mysite.com/postTest.php");

instead of

HttpPost httppost = new HttpPost("http:/mysite.com/postTest.php");
