Question

How can I send my username and password to the server and get response from the server using httpclient in Android? I researched many websites but I couldn’t find anything I want.

Answer 1

Make a class Adapter and put this code…Here i assume you are using json webService.

public String login(String uname, String password)
{
    InputStream is = null;
    String result = "";
    ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();

    try 
    {   
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost("Your Url");

        nameValuePairs.add(new BasicNameValuePair("emailid", uname));
        nameValuePairs.add(new BasicNameValuePair("password", password));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        HttpResponse response = httpclient.execute(httppost);
        HttpEntity entity = response.getEntity();

        is = entity.getContent();
    }
    catch (Exception e)
    {
        Log.e("log_tag", "Error in http connection " + e.toString());
    }

    // convert response to string
    try 
    {
        BufferedReader reader = new BufferedReader(new InputStreamReader( is, "iso-8859-1"), 8);
        StringBuilder sb = new StringBuilder();
        String line = null;

        while ((line = reader.readLine()) != null) 
        {
            sb.append(line).append("\n");
        }

        is.close();
        result = sb.toString();

        Log.v("log","Result: " + result);
    } 
    catch (Exception e)
    {
        Log.v("log", "Error converting result " + e.toString());
    }

    return result;
}

and make a call like this…

Adapter adb = new Adapter();
response = adb.login(edtLoginemail.getText().toString(), edtLoginPassword.getText().toString());
