Answer 1

public String getIpAddress() {
String ip;
   try {
        HttpClient httpclient = new DefaultHttpClient();
        HttpGet httpget = new HttpGet("http://ip2country.sourceforge.net/ip2c.php?format=JSON");
        // HttpGet httpget = new HttpGet("http://whatismyip.com.au/");
        // HttpGet httpget = new HttpGet("http://www.whatismyip.org/");
        HttpResponse response;

        response = httpclient.execute(httpget);
        //Log.i("externalip",response.getStatusLine().toString());

        HttpEntity entity = response.getEntity();
        entity.getContentLength();
        str = EntityUtils.toString(entity);
        Toast.makeText(getApplicationContext(), str, Toast.LENGTH_LONG).show();
        JSONObject json_data = new JSONObject(str);
        ip = json_data.getString("ip");
        Toast.makeText(getApplicationContext(), ip, Toast.LENGTH_LONG).show();
    }
    catch (Exception e){...}

  return ip;
}
