Using the date from DatePicker in URL for webservice

[franssen00]

Okayyyy, so in my code at the moment today's date is being read into the webservice url using the following snippet of code:\[code\]Calendar c = Calendar.getInstance();System.out.println("Current time => " + c.getTime());SimpleDateFormat df = new SimpleDateFormat("dd/MM");String formattedDate = df.format(c.getTime());\[/code\]I want it to automatically be todays date but I also want the user to be able to select a different date from the DatePicker and find the sunrise/sunset values for that particular date.I'm guessing this is simple and I'm just being a bit dim so any help would be appreciated, here is my code:\[code\]package richgrundy.learnphotography;import java.io.IOException;import java.io.InputStream;import java.io.StringReader;import java.text.SimpleDateFormat;import java.util.Calendar;import javax.xml.parsers.DocumentBuilder;import javax.xml.parsers.DocumentBuilderFactory;import org.apache.http.HttpEntity;import org.apache.http.HttpResponse;import org.apache.http.client.HttpClient;import org.apache.http.client.methods.HttpGet;import org.apache.http.impl.client.DefaultHttpClient;import org.apache.http.protocol.BasicHttpContext;import org.apache.http.protocol.HttpContext;import org.w3c.dom.Document;import org.xml.sax.InputSource;import android.app.Activity;import android.app.FragmentTransaction;import android.content.Context;import android.location.Location;import android.location.LocationListener;import android.location.LocationManager;import android.os.AsyncTask;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.Spinner;import android.widget.TextView;public class SunriseSunset extends Activity implements OnClickListener { public Button getLocation;
