Can't Log to an aspx form from Android

I have a code to make an httpPost, but i can't log using the parameters in the array, but if i make all the complete url i will log with no problem !, what am i missing ?
String URL = "http://domain.com/projexct/form.aspx"; //won't work
// String URL = "http://domain.com/projexct/form.aspx?user=aa&pass=11";
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(URL);
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("user", "aa"));
nameValuePairs.add(new BasicNameValuePair("pass", "11"));
httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Execute HTTP Post Request
HttpResponse response = httpClient.execute(httpPost);
EDIT1
It doesn't throw and error, but if i use the parames in namevaluePairs it shows just the login page, if i use the URL commented it will actualy log in.

Login and download programmatically in Android

I want to make an application for a web page that needs POST login. After that I'll download an HTML page and read its tags and perform some tasks to display some information.
Before I begin, I want to know if there is a way login in to this page using POST, somehow programmatically and download the page.

this is a way to send post request:
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://www.example.com/login.php");
try
{
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("name", "value"));
Httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
String result = EntityUtils.toString(response.getEntity());
}
catch(Exception e)
{
e.printStackTrace();
}
you can send your information in order to login to page.!

Making an HTTP post request to the Google Play Android Developer API

I'm trying to authorize the Google Play Android Developer API. I'm at the step where I need to make an HTTP post request to exchange the authorization code for an access token and a refresh token. Google gives the following example request:
POST /o/oauth2/token HTTP/1.1
Host: accounts.google.com
Content-Type: application/x-www-form-urlencoded
code=4/v6xr77ewYqhvHSyW6UJ1w7jKwAzu&
client_id=8819981768.apps.googleusercontent.com&
client_secret={client_secret}&
redirect_uri=https://oauth2-login-demo.appspot.com/code&
grant_type=authorization_code
I'm confused... First of all, for an installed application (Android) no client_secret is given. I created a web application for the same project in the Google API Console and this gave me a client_secret, so I used that, even though there is no web application. The following code gives me an "invalid_grant" error:
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("https://accounts.google.com/o/oauth2/token");
try {
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(5);
nameValuePairs.add(new BasicNameValuePair("code", "CODE"));
nameValuePairs.add(new BasicNameValuePair("client_id", "CLIENT_ID"));
nameValuePairs.add(new BasicNameValuePair("client_secret", "CLIENT_SECRET"));
nameValuePairs.add(new BasicNameValuePair("redirect_uri", "urn:ietf:wg:oauth:2.0:oob"));
nameValuePairs.add(new BasicNameValuePair("grant_type", "authorization_code"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
....
Taking out the client_secret entirely gave me an "invalid_request" error.

This is how I solved it. I ended up using a Web Applcation. See more details in my response here.
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("https://accounts.google.com/o/oauth2/token");
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(4);
nameValuePairs.add(new BasicNameValuePair("grant_type", "refresh_token"));
nameValuePairs.add(new BasicNameValuePair("client_id", CLIENT_ID));
nameValuePairs.add(new BasicNameValuePair("client_secret", CLIENT_SECRET));
nameValuePairs.add(new BasicNameValuePair("refresh_token", REFRESH_TOKEN));
post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = client.execute(post);

I have managed to redeem access code for access token from android app without the help of web application by simply eliminating the client_secret key as it is not applicable for installed applications.
HttpPost httppost = new HttpPost("https://accounts.google.com/o/oauth2/token");
httppost.setHeader("Content-type", "application/x-www-form-urlencoded");
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(4);
nameValuePairs.add(new BasicNameValuePair("grant_type", "authorization_code"));
nameValuePairs.add(new BasicNameValuePair("client_id", BLOGGER_CLIENT_ID));
nameValuePairs.add(new BasicNameValuePair("redirect_uri", "http://localhost"));
nameValuePairs.add(new BasicNameValuePair("code", BLOGGER_ACCESS_CODE));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpClient httpClient = new DefaultHttpClient(myParams);
response = httpClient.execute(httppost);
String returnedJsonStr = EntityUtils.toString(response.getEntity());
JSONObject jsonObject = new JSONObject(returnedJsonStr);
String receivedToken = jsonObject.getString("access_token");
Reason to post this comment is that your solution can be misleading to someone who might think only way to get access token in mobile apps is via web-application, which I thought after reading your post few minutes ago !
To avoid invalid_grant error follow this code:

HttpPost returns only part of response body

I'm performing login on server using HttpPost method.
CommonsConnection.initHttpConnection();
HttpResponse response;
String contentOfMyInputStream;
HttpGet initPostMethod = new HttpGet("https://stat.volia.com:8443/ktvinet/index.jsp");
response = CommonsConnection.hc.execute(initPostMethod);
HttpPost Statistics = new HttpPost("https://stat.volia.com:8443/ktvinet/j_security_check");
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(3);
nameValuePairs.add(new BasicNameValuePair("j_username", "username"));
nameValuePairs.add(new BasicNameValuePair("j_password", "password"));
nameValuePairs.add(new BasicNameValuePair("submit", "%C2%EE%E9%F2%E8"));
Statistics.setEntity(new UrlEncodedFormEntity(nameValuePairs));
response = CommonsConnection.hc.execute(Statistics);
HttpGet mainPage = new HttpGet("https://stat.volia.com:8443/ktvinet/main.do");
response = CommonsConnection.hc.execute(mainPage);
contentOfMyInputStream = EntityUtils.toString(response.getEntity());
The response I get - body of webpage - is like 1/5 part of webpage, which ends with "...".
Am I missing some parameter for httpclient ?

How are you examining the response? if you're looking int he debugger or something similar, it may well truncate long strings, try dumping it in a file.

Logcat displays only part of long string response.

Post data to server in android

I want to send some data to a server through POST method in android. I am using the following code
DefaultHttpClient hc=new DefaultHttpClient();
ResponseHandler <String> res=new BasicResponseHandler();
HttpPost postMethod=new HttpPost(url);
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("name", "value"));
nameValuePairs.add(new BasicNameValuePair("password", "value"));
postMethod.setEntity(new UrlEncodedFormEntity(nameValuePairs));
String response=hc.execute(postMethod,res);
But I am getting the error response in my response xml. The error message is cookies are disabled in client machine. How do I need to enable cookies in android ?

You need to handle cookies with your request. See this and this related questions.
