не запускается kryonet сервер на android устройстве

Я сейчас занимаюсь разработкой небольшой android игры на движке libGDX и решил сделать мультиплеер в игре. Для реализации этой цели я решил воспользоваться kryonet и написать небольшой сервер. Когда я запускаю приложение на ПК, сервер спокойно запускается, но, когда приложение запускается на android устройстве или на android эмуляторе, сервер не запускается, и приложение не падает. Вот код экрана в котором происходит запуск сервера и реализации клиента и сервера

сервер:

и клиент:

public class ClientListener extends Listener {

    }

    public void received(Connection connection, Object object) {
        if (object instanceof PacketMessage) {

            if (message.text == "start_game_event") {
                game.setScreen(new PlayScreen(game, fighter, map));
            }

            if (message.text.startsWith("map: ")) {
                map = message.text.replace("map: ", "");
            }
        }
    }
}
