I tried the code that you have posted earlier, but it seems answer as "false". Let me know how to fix this ?

nice code thanks. but, is there any specific way to send that post via a specified port? i just use new HttpPost(http://mywebsite.com:1234/post.php) and I get a NoHttpResponseException, although I checked and got a positive answer if a connection can be established .
Can you give me some advice please!

Thanks

Thank you for your patiences and help...

textview is not spelled correctly!

Line: tv = (TextView)findViewById(R.id.textveiw);

add

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

to the manifest

Thanks a lot for the code you provided.
It really helped me out and was very easy to follow.
Thanks to Wadael, too, of course.

Thanks a lot for your code, you saved me time as I'm new to Android.
I did some refactoring so that it can be used and reused in one's projects.

I get 2 errors:

The method toASCIIString is undefined for the type String

and

the local variable re is never used

Any suggestions ?

Can someone help me with this issue from the example above please? I'm a newbie to Android and not the best with Java..



I could really use having this POST method running for good.

How can I make this variable be read?

This tutorial is driving me nuts!!!!! Sometimes it's working sometimes it's not.. I've been around this for two days... can ANYBODY help me please?

Here's the code:

A HTTPPoster Class on which I didn't change anything:


And the method being used on the event of a Click on another class



Please... what the hell am I doing wrong ?
Besides saying ''re'' is never read.. sometimes it passes the strings values sometimes it doesn't ..

My POST attributes to receive in the UT1.php file are ''name'' and ''email''.

How can I make this work? I'm kinda getting desperate !

Could someone please post a solution that works. It looks like a lot of people can't get this working either. Thanks.

Hi guys!
I need a little help.. I've tested every code on this forum and other websites, sanitizing them or using as written, but I always return the same error: 417 Expectation Failed.. I don't know anything about status error different from 404, 500, and so on..
Someone with more experience have a clue??
Thanks you a lot! If someone will find an answer I'll work hard for this forum with some open code!!

Same, I can't get any of the code posted to work.

Chances are the reason why your code isn't working is because you don't understand how to build an HTTP request. The code is fine, your headers and content probably isn't!

Using a network protocol analyser (such as Wireshark), or FireBug or Chrome's built in development tools, read the POST requests you make to websites then rebuild them (using the same headers) in Android.

New to anddev.org. Hello all. I tried your script i added a little bit more to read a reply. Now using your data in php i have

Code: Select all

<?php>
echo "My id is ". $_POST['id']


When i display it on my android 2.1 phone it just says "My id is "

The web isn't getting the $_POST am i not getting the data correct using $_POST.

I even tried in php to use "print_r($_POST);" and all it displays array()

pre Thanks

Thanks a lot for the code.. but the code provided above working perfectly as an independent application..
but when i try to call this from another activity, the application closes with an exception.


Please help me resolve this error at the earliest. I have a demo on monday of my applicaiton.

Code: Select all

public String POST(String action, String var1, String var2) {
      String answer = null;
      HttpParams params = new BasicHttpParams();
      params.setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);

      HttpClient httpclient = new DefaultHttpClient();
      HttpPost httppost = new HttpPost(url);
      
      try {
         List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
         // Your DATA
         nameValuePairs.add(new BasicNameValuePair("action", action));
         nameValuePairs.add(new BasicNameValuePair("var1", var1));
         nameValuePairs.add(new BasicNameValuePair("var2", var2));

         httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
         HttpResponse response = httpclient.execute(httppost);
         HttpEntity resEntity = response.getEntity();
         String ReTurned = EntityUtils.toString(resEntity);
         answer = ReTurned;
         Toast.makeText(this, answer, Toast.LENGTH_LONG).show();
      } catch (ClientProtocolException e) {
         Toast.makeText(this, "There was an issue Try again later", Toast.LENGTH_LONG).show();
      } catch (IOException e) {
         Toast.makeText(this, "There was an IO issue Try again later", Toast.LENGTH_LONG).show();
         e.printStackTrace();
      }
      
      return answer;
   }

I fixed my issue by adding in

Code: Select all

      HttpParams params = new BasicHttpParams();
      params.setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);

Also to the last poster the above i believe maybe what you are looking for.
