Null Pointer Exception when trying to load Tiled Map

Question

Hi App I keep getting a null pointer Exception when I try to load my tiled map. Does anybody know how i can solve this issue. (Using libgdx and Tiled)

Here is the code

private TiledMap map;
private OrthogonalTiledMapRenderer renderer;


@Override
public void show() {
    // TODO Auto-generated method stub
    map = new TmxMapLoader().load("trial.tmx");

    renderer = new OrthogonalTiledMapRenderer(map, 2f);
    
}

@Override
public void render(float delta) {
    // TODO Auto-generated method stub\


    
}

@Override
public void resize(int width, int height) {
    // TODO Auto-generated method stub
    
}

@Override
public void pause() {
    // TODO Auto-generated method stub
    
}

@Override
public void resume() {
    // TODO Auto-generated method stub
    
}

@Override
public void hide() {
    // TODO Auto-generated method stub
    dispose();
}

@Override
public void dispose() {
    // TODO Auto-generated method stub
    map.dispose();
    renderer.dispose();
}

And Here is the error message I keep getting
