I'm trying to pass a bundle of two values from a started class to my landnav app, but according to the debug nothing is getting passed, does anyone have any ideas why?

package edu.elon.cs.mobile;

import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.EditText;

public class PointEntry extends Activity{

private Button calc;
private EditText longi;
private EditText lati;
private double longid;
private double latd;


public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.pointentry);

    calc = (Button) findViewById(R.id.coorCalcButton);
    calc.setOnClickListener(landNavButtonListener);

    longi = (EditText) findViewById(R.id.longitudeedit);
    lati = (EditText) findViewById(R.id.latitudeedit);
}

private void startLandNav() {

    Intent intent = new Intent(this, LandNav.class);
    startActivityForResult(intent, 0);
}


private OnClickListener landNavButtonListener = new OnClickListener() {

    @Override
    public void onClick(View arg0) {
        Bundle bundle = new Bundle();
        bundle.putDouble("longKey", longid);
        bundle.putDouble("latKey", latd);
        longid = Double.parseDouble(longi.getText().toString());
        latd = Double.parseDouble(lati.getText().toString());
        startLandNav();
    }


};

}

This is the class that is suppose to take the second point
