Foursquare签到

Question

我在Android上工作。我已经完成了在Android应用程序中集成Foursquare所需的几乎所有工作。

现在，我正尝试在此应用程序中添加签入功能。

这是我在android中为foursquare签到的代码：

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

请告诉我我做得对不对？实际上，我不知道在我们的android应用程序中通过Foursquare为一个会场添加签到功能的步骤是什么。

    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");

    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;
}

尝试使用此方法发布带有空ArrayList和空contentType的签入url。

我是这样解决我的问题的：

    try {

                     HttpPost post = new 
   HttpPost("https://api.foursquare.com/v2/checkins/add?venueId="+mNearbyList.get(position).id+"&shout=great....&broadcast=public&oauth_token="mytoken");



                        HttpClient hc=new DefaultHttpClient();
                        HttpResponse rp = hc.execute(post);
                    //    Log.v(TAG,"response from server "+EntityUtils.toString(rp.getEntity()));  
                          if (rp.getStatusLine().getStatusCode() == HttpStatus.SC_OK) 
                         {
                              Toast.makeText(PlacetoCheckin.this, "Done", Toast.LENGTH_SHORT).show();
                              String response = EntityUtils
                                .toString(rp.getEntity());
                        Log.v(TAG,
                                "response from server====="
                                        + response);
                          }
               }
               catch(Exception e){}
              }
            });

谷歌代码上有一些旧的安卓代码，这些代码是由FourSquare为一个安卓FourSquare应用程序编写的。也许你可以在那里找到一些例子。
