import android.os.Bundle;

public class MapasSimplesActivity extends MapActivity { \ erro nesta linha, na MapActivity

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main); \\erro aqui nesta linha
    MapView mapView = (MapView) findViewById(R.id.map_view) ;\\erro aqui nesta linha
    mapView.setClickable(true) ;
