Andengine BlackBoxes Sprites not loading correctly

Question

Hi im new to developing for android and im having some troubles with my sprites not loading right. My code was perfectly fine before i started adding in a AnalogOnScreenControl now all my sprites including my AnalogOnScreenControl just show a black box. The nub on the control is also black. the only things that arent black are the blackground and the ground itself. heres my code:

public class MainActivity extends BaseGameActivity {

Scene scene;
protected static final int CAMERA_WIDTH = 256;
protected static final int CAMERA_HEIGHT = 144;
BitmapTextureAtlas playerTexture;
ITextureRegion playerTextureRegion;
PhysicsWorld physicsWorld;
private Camera mCamera;

private TextureRegion controlTextureRegion;
private TextureRegion controlNubTextureRegion;

@Override
public EngineOptions onCreateEngineOptions() {
    // TODO Auto-generated method stub
    mCamera = new Camera(0, 0, CAMERA_WIDTH, CAMERA_HEIGHT); // Camera
                                                                    // Defines
                                                                    // How
                                                                    // we
                                                                    // see
                                                                    // the
                                                                    // screen
    EngineOptions options = new EngineOptions(true,
            ScreenOrientation.LANDSCAPE_FIXED, new RatioResolutionPolicy(
                    CAMERA_WIDTH, CAMERA_HEIGHT), mCamera); // set screen
                                                            // orientation
                                                            // and camera to
                                                            // engine
                                                            // options
    return options; // return those options
}

@Override
public void onCreateResources(
        OnCreateResourcesCallback pOnCreateResourcesCallback)
        throws Exception {
    // TODO Auto-generated method stub
    loadGfx(); // load graphics
    pOnCreateResourcesCallback.onCreateResourcesFinished(); // add callback
}

private void loadGfx() {
    // TODO Auto-generated method stub
    BitmapTextureAtlasTextureRegionFactory.setAssetBasePath("gfx/");
    playerTexture = new BitmapTextureAtlas(getTextureManager(), 88, 23);
    playerTextureRegion = BitmapTextureAtlasTextureRegionFactory
            .createFromAsset(playerTexture, getBaseContext(),
                    "mrsaispritesheet.png", 0, 0);

    this.controlTextureRegion = BitmapTextureAtlasTextureRegionFactory.createFromAsset(new BuildableBitmapTextureAtlas(getTextureManager(), 32, 32), this.getAssets(), "basecontrol.png", false);
    this.controlNubTextureRegion = BitmapTextureAtlasTextureRegionFactory.createFromAsset(new BuildableBitmapTextureAtlas(getTextureManager(), 32, 32), this.getAssets(), "controlnub.png", false); 


}

@Override

        throws Exception {

    final AnalogOnScreenControl control = new AnalogOnScreenControl(0,
            CAMERA_HEIGHT - this.controlTextureRegion.getHeight(),
            this.mCamera, this.controlTextureRegion,
            this.controlNubTextureRegion, 200,
            getVertexBufferObjectManager(),
            new IAnalogOnScreenControlListener() {

                @Override
                public void onControlChange(
                        BaseOnScreenControl pBaseOnScreenControl,
                        float pValueX, float pValueY) {
                    // TODO Auto-generated method stub

                }

                @Override
                public void onControlClick(
                        AnalogOnScreenControl pAnalogOnScreenControl) {
                    // TODO Auto-generated method stub

                }

    });




    this.scene = new Scene();
    this.scene.setBackground(new Background(0, 125, 58));

    physicsWorld = new PhysicsWorld(new Vector2(0,
            SensorManager.GRAVITY_MOON), false);
    this.scene.registerUpdateHandler(physicsWorld);
    createWalls();
    this.scene.setChildScene(control);
    pOnCreateSceneCallback.onCreateSceneFinished(this.scene);

}

private void createWalls() {
    // TODO Auto-generated method stub
    FixtureDef WALL_FIX = PhysicsFactory.createFixtureDef(0.0f, 0.0f, 0.0f);
    Rectangle ground = new Rectangle(0, CAMERA_HEIGHT - 15, CAMERA_WIDTH,
            15, this.mEngine.getVertexBufferObjectManager());
    ground.setColor(new Color(15, 50, 0));
    PhysicsFactory.createBoxBody(physicsWorld, ground, BodyType.StaticBody,
            WALL_FIX);
    this.scene.attachChild(ground);
}

@Override
public void onPopulateScene(Scene pScene,
        OnPopulateSceneCallback pOnPopulateSceneCallback) throws Exception {
    // TODO Auto-generated method stub

    Sprite sPlayer = new Sprite(CAMERA_WIDTH / 2, CAMERA_HEIGHT / 2,
            playerTextureRegion,
            this.mEngine.getVertexBufferObjectManager());

    final FixtureDef PLAYER_FIX = PhysicsFactory.createFixtureDef(10.0f,
            0.0f, 0.0f);

    Body body = PhysicsFactory.createBoxBody(physicsWorld, sPlayer,
            BodyType.DynamicBody, PLAYER_FIX);
    this.scene.attachChild(sPlayer);
    physicsWorld.registerPhysicsConnector(new PhysicsConnector(sPlayer,
            body, true, false));

    pOnPopulateSceneCallback.onPopulateSceneFinished();
}

}

Any idea what im doing wrong? help is apreciated :]

You need to call the load function to load your texture after creating them. Like this:

playerTexture.load();

This line has to be just after creating them
