Question

I’m making a POST request with login/pass and opening the site with an Intent. The site is opening but it is not logged in. What is wrong?

    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("http://mysite.co/login.php");

    try {

        // Add your data
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
        nameValuePairs.add(new BasicNameValuePair("pass", "mypass"));
        nameValuePairs.add(new BasicNameValuePair("user", "myuser"));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        // Execute HTTP Post Request
        HttpResponse response = httpclient.execute(httppost);
    } catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
    } catch (IOException e) {
        // TODO Auto-generated catch block
    }

    Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://mysite.com"));
    startActivity(browserIntent);

The problems is that you are login into a website in your application. So, all cookies (which shows whether you are logged in or not) are stored in response.

You send new intent, which open a browser. However, browser doesn’t have access to these cookies which are saved in your response. So when it tries to access website, the website doesn’t get a cookie and thinks that you aren’t logged it.

I would say you should remove whole first part of this code and just have something like this:

 Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://mysite.com/login.php?user=myuser&pass=mypass"));
    startActivity(browserIntent);

This way the broswer will send authentication information and will receive a cookie in response and use it for any following communications.
