Set up HTTPPOST android?

I want to set up httppost to my server.
For now I have address for emulator, but now I want to test app online.
Here is the code:

HttpClient httpClient = new DefaultHttpClient();
 HttpPost httpPost = new HttpPost("http://10.0.2.2/posloviPodaci/index.php");
 

How to set up address for my server, which I have online?
Thanks.
