Estoy creando una aplicación que obtiene datos de países (nombre, latitud, longitud, ...) deJSON y crea unlistview, donde cada elemento es un país diferente.

Esa parte está funcionando pero, cada vez que hago clic en un elemento, se abre MapActivity, con el mapa centrado en ese país. El problema es que no puedo enviar las coordenadas de MainActivity a MapsActivity.

public class TodasAsCategorias extends AppCompatActivity {

private String TAG = TodasAsCategorias.class.getSimpleName();
private ProgressDialog pDialog;
private ListView lv;
private static String url = "http://*************/api/continent/any/country/all?id=siF1uXXEsltXOi5CWlSIzy7EABlnE5iF33bnNmfAHJiYXYNmjY";
ArrayList<HashMap<String, String>> listaPaises;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_todas_as_categorias);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setTitle("Categorias");

    listaPaises = new ArrayList<>();
    lv = (ListView) findViewById(R.id.list);
    new GetPaises().execute();
}


@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case android.R.id.home:
            finish();
            return true;
        default:
            return super.onOptionsItemSelected(item);
    }
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.main, menu);
    menu.findItem(R.id.spinner_cat).setVisible(false);
    menu.findItem(R.id.spinner_pais).setVisible(false);
    return true;
}

private class GetPaises extends AsyncTask<Void, Void, Void> implements Serializable {
    @Override
