package com.android.login.test;

/* new_auth_data=1&     - If there is new user ot password changes
 * debug_data=1&        - Debugging data sent from terminal
 * client_api_ver=1.5.1.422&    - API version of clients terminal
 * timestamp=1314195661&        - THE timestamp of first sync of new device 
 * password_hash=d2824b50d07cfed3d82a480d5d87437af11a4f7e&      - A valid password hash

            try {
                httppost.setEntity(new UrlEncodedFormEntity(postParameters));

                HttpResponse response = httpclient.execute(httppost);
                Log.d("myapp", "response " + response.getEntity());

                String responseBody = EntityUtils.toString(response.getEntity());

                error.setText(responseBody);
            } catch (Exception e) {
                username.setText(e.toString());
            }

        }
    });

}

}

I'm setting all the params in code because as I said it's just for test.As a result after the executing http post I need to send to the server something like that :

new_auth_data=1&debug_data=1&client_api_ver=1.5.1.422&timestamp=1314195661&password_hash=d2824b50d07cfed3d82a480d5d87437af11a4f7e&set_locale=en_US&device_os_type=iPhone%20Simulator%204.3.2&username_hash=6d229fe6593f5250653e3b29184a6e370fc7ffe5&device_sync_type=3&device_identification_string=iPhone%20Simulator%204.3.2&device_resolution=320x480&device_identificator=255634997

How can I fix this so I can test a login?any ideas or suggestions are welcomed! Thanks in advance!

Answer 1

To get the response you should do like this:

        HttpEntity entity = response.getEntity();

        String html = null;
        if (entity != null) {
            InputStream instream = entity.getContent();
            try {
                html = streamToString(instream);
            } finally {
                instream.close();
            }
        }

If you have any further questions don't hesitate to ask me.

Have you checked whether you can login to your server using desktop browser or some utility like curl command line utility? Username and password hash mentioned in your comment and in code are different. You should be able to see parameters received on server with the help of server logs.
