Question

I am working in Android. I have done almost all the work which is required for Foursquare integration in an Android application.

Now I am trying to add check in functionality in this application.

This is my code in android for foursquare check-in :

URL url = new URL("https://api.foursquare.com/v2/checkins/add?venueId=4d6a73bafd7ea35d0c08b24a&shout=great....&broadcast=public&oauth_token=myauthtoken");
URLConnection conn = url.openConnection();

Please tell me whether I am doing right or not? Actually I dont know that what is the procedure to add check in functionality for a venue through Foursquare in our android application.

DefaultHttpClient httpClient;

private String ret;

HttpPost httpPost = null;

public String sendPost(String url, List<NameValuePair> data, String contentType) {
    ret = null;

    httpClient.getParams().setParameter(ClientPNames.COOKIE_POLICY, CookiePolicy.RFC_2109);

    httpPost = new HttpPost(url);
    response = null;

    StringEntity tmp = null;

    httpPost.setHeader("User-Agent", "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/535.1 (KHTML, like Gecko) Chrome/13.0.782.215 Safari/535.1");
    httpPost.setHeader("Accept", "text/html,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5");

    if (contentType != null) {
        httpPost.setHeader("Content-Type", contentType);
    } else {
        httpPost.setHeader("Content-Type", "application/x-www-form-urlencoded");
    }

    try {
        tmp = new UrlEncodedFormEntity(data);
    } catch (UnsupportedEncodingException e) {

    }

    httpPost.setEntity(tmp);
    response = httpClient.execute(httpPost, localContext);


    if (response != null) {
        ret = EntityUtils.toString(response.getEntity());
    }


    return ret;
}

Try using this method to post your checkin url with an empty ArrayList and null contentType.
