android google maps

THis helps u to open the inbuilts maps in android.

import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;

public class MapActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Intent intent = new Intent(android.content.Intent.ACTION_VIEW,
                Uri.parse("http://maps.google.com/maps?saddr=20.344,34.34&daddr=20.5666,45.345"));
                startActivity(intent);

        setContentView(R.layout.main);
