android - GPS - Getting the distance,time while running and walking

Question

i have a situation where i need to use GPS technique.

i need to find the distance between two points when the person is walking.

When the person starts walking he will click on Start button and when he stops he clicks on stop button

after this it should show him

1.time taken 2.Distance travelled in Kms. 3.from where to where(places name) eg: a to b

Do i need to have google maps for this?

I saw the code here link to get the current location which gives me latitude longitude.

please help how to go with this

This is the code i am using

private EditText editTextShowLocation;
    private Button buttonGetLocation;
    private ProgressBar progress;

    private LocationManager locManager;
    private LocationListener locListener = new MyLocationListener();

    private boolean gps_enabled = false;
    private boolean network_enabled = false;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        editTextShowLocation = (EditText) findViewById(R.id.editTextShowLocation);

        progress = (ProgressBar) findViewById(R.id.progressBar1);
        progress.setVisibility(View.GONE);

        buttonGetLocation = (Button) findViewById(R.id.buttonGetLocation);
        buttonGetLocation.setOnClickListener(this);

        locManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
    }

    @Override
    public void onClick(View v) {
        progress.setVisibility(View.VISIBLE);
        // exceptions will be thrown if provider is not permitted.
        try {
            gps_enabled = locManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
        } catch (Exception ex) {
        }
        try {
            network_enabled = locManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
        } catch (Exception ex) {
        }

        // don't start listeners if no provider is enabled
        if (!gps_enabled && !network_enabled) {
            AlertDialog.Builder builder = new Builder(this);
            builder.setTitle("Attention!");
            builder.setMessage("Sorry, location is not determined. Please enable location providers");
            builder.setPositiveButton("OK", this);
            builder.setNeutralButton("Cancel", this);
            builder.create().show();
            progress.setVisibility(View.GONE);
        }

        if (gps_enabled) {
            locManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locListener);
        }
        if (network_enabled) {
            locManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locListener);
        }
    }

    class MyLocationListener implements LocationListener {
        @Override
        public void onLocationChanged(Location location) {
            if (location != null) {
                // This needs to stop getting the location data and save the battery power.
                locManager.removeUpdates(locListener); 

                String londitude = "Londitude: " + location.getLongitude();
                String latitude = "Latitude: " + location.getLatitude();
                String altitiude = "Altitiude: " + location.getAltitude();
                String accuracy = "Accuracy: " + location.getAccuracy();
                String time = "Time: " + location.getTime();

                editTextShowLocation.setText(londitude + "
" + latitude + "
" + altitiude + "
" + accuracy + "
" + time);
                progress.setVisibility(View.GONE);
            } 
        }

        @Override
        public void onProviderDisabled(String provider) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onProviderEnabled(String provider) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onStatusChanged(String provider, int status, Bundle extras) {
            // TODO Auto-generated method stub

        }
    }

    @Override
    public void onClick(DialogInterface dialog, int which) {
        if(which == DialogInterface.BUTTON_NEUTRAL){
            editTextShowLocation.setText("Sorry, location is not determined. To fix this please enable location providers");
        }else if (which == DialogInterface.BUTTON_POSITIVE) {
            startActivity(new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS));
        }
    }

It is showing the Logitude Latitude which i am entering from emulator control.

In this i am manually entering the details of longitude and latitude by going to window->showview->other->emulator control for testing in the emulator but what i need is i will have two edittext where i enter the place name(A) and (B)

it should give me the distance

please help
