          $query1=mysql_query($query);
            if ($query1="")
         {echo "unsuccessfull";

        {   
            if(fname.getText().length()== 0)

                HttpResponse response = httpclient.execute(httppost);

My code is not working @ when i enter my data on My emulator my data does not goes into my server database instead of that some blank data goes into database Can anyone please help me how can I do the same.Also Please point out what is the mistake in My code.

Answer 1

Error was on this line I feel:

httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs,HTTP.UTF_16));

I replaced this with,

UrlEncodedFormEntity URLEntity = new UrlEncodedFormEntity(nameValuePairs);
httppost.setEntity(URLEntity );

Answer 2

Did you try:

DefaultHttpClient client = new DefaultHttpClient();

instead of HttpClient client = new DefaultHttpClient();

And let me know

Answer 3

I would suggest you to check the status of your web call, you can check it through:

int status = response.getStatusLine().getStatusCode();

If you getting 200 as status code then its a successful web call otherwise something is going wrong.

Answer 4

@Parth Dani You have a error in the php file...You are actually making a POST call throug your program.
HttpPost httppost = new HttpPost("http://android/android_user.php");

and you are using GEt in your Php code ...what you have to do is just replace GET with POST in your Php code and you're done.
