Question

Hi Everyone I am using the code given here What is the simplest and most robust way to get the user's current location on Android? to get current location But I am getting the ClassNotFoundExecption Here is my complete code:

//MapActivity code:

package com.example.gmaps;
import com.example.gmaps.MyLocation.LocationResult;
import com.google.android.maps.MapActivity;
import android.location.Location;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.widget.Toast;

public class MainActivity extends MapActivity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    LocationResult locationResult = new LocationResult(){
        @Override
        public void gotLocation(Location location){
            //Got the location!

            Toast.makeText(getApplicationContext(), "I got the location", Toast.LENGTH_LONG).show();
        }
    };
    MyLocation myLocation = new MyLocation();
    myLocation.getLocation(MainActivity.this, locationResult);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
}

@Override
protected boolean isRouteDisplayed() {
    // TODO Auto-generated method stub
    return false;
}

Did you add above code your AndroidManifest.xml ?
