Как загрузить файл .TMX в Cocos2d Android с помощью cocos2d-android.jar

Это мой первый вопрос, и я тщательно искал в SO, чтобы найти решение моей проблемы. Но я не понимаю. Я разрабатываю демо-игру на Android, используя cocos2d-android.jar (Cococs2d, а не Cocos2d-x). Ниже приведен мой код Java для загрузки файла TMX:

public class GameLayer extends CCLayer {

    private CGSize _winSize;
    protected ArrayList<CCSprite> _targets;
    protected ArrayList<CCSprite> _projectiles;
    protected int _projectilesDestroyed;
    protected CCSprite _player;
    protected CCSprite _nextProjectile;
    protected CCTMXTiledMap _map;
    protected CCTMXLayer _background;
    protected CCTMXLayer _foreground;
    protected CCTMXLayer _meta;
    protected CCTMXObjectGroup _objects;
    protected HashMap<String, String> _spawnPoint;

    protected GameLayer() {
        super();
        _winSize = CCDirector.sharedDirector().displaySize();
        _targets = new ArrayList<CCSprite>();
        _projectiles = new ArrayList<CCSprite>();
        _projectilesDestroyed = 0;

        // Get TMX Map and associated layers/groups
        _map = CCTMXTiledMap.tiledMap("MyTiledMap.tmx"); // The app is crashing at this line
        _background = _map.layerNamed("Background");
        _foreground = _map.layerNamed("Foreground");
        _meta  = _map.layerNamed("Meta");
        _meta.setVisible(false);

        _objects = _map.objectGroupNamed("Objects");
        if(_objects == null){
            Log.e("BoxAway", "Tile map has no objects..");
        }

        // Add my background layer
        // TODO: Position layer in the correct spot.
//      addChild(_background);
        addChild(_map);

        _spawnPoint = _objects.objectNamed("SpawnPoint");

        _player = CCSprite.sprite("player.png");

        setPlayerPosition(CGPoint.ccp(100.0f, 100.0f));

        addChild(_player);
        setViewPointCentered(_player.getPosition());

        float y = 0.0f;

        x = Math.max(pos.x, _winSize.width / 2);
        y = Math.max(pos.y, _winSize.height / 2);

        x = Math.min(x, (_map.getMapSize().width * _map.getTileSize().width)
                - _winSize.width / 2);
        y = Math.min(y, (_map.getMapSize().height * _map.getTileSize().height)
                - _winSize.height / 2);

Может кто-нибудь указать мне в правильном направлении, пожалуйста? Также приветствуются другие источники/ссылки, показывающие загрузку и перемещение тайловых карт с помощью cocos2d в Android.
