import com.jiramot.foursquare.android.R;
import com.mukesh.foursquare.android.Foursquare.DialogListener;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;

public class Main extends Activity {

Foursquare foursquare;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
foursquare = new Foursquare("Client Id","Client Secret","Redirect Url");

foursquare.authorize(this, new FoursquareAuthenDialogListener());

private class FoursquareAuthenDialogListener implements DialogListener {

@Override
public void onComplete(Bundle values) {

 try {
     String aa = null;
     aa = foursquare.request("users/self");
     Log.d("Foursquare-Main", aa);
 } catch (MalformedURLException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (IOException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();

@Override
