Can't render a Tiled Map in libgdx

Question

I have been trying to render a tiled map to my LibGDX project but nothing shown on the screen, I followed this tutorial from here http://www.gamefromscratch.com/post/2014/04/16/LibGDX-Tutorial-11-Tiled-Maps-Part-1-Simple-Orthogonal-Maps.aspx.

Could the problem be that I didn't set the position of the camera right?

This is my code

  package com.mygdx.game;

import com.badlogic.gdx.ApplicationAdapter;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.Input;
import com.badlogic.gdx.InputProcessor;
import com.badlogic.gdx.graphics.GL20;
import com.badlogic.gdx.graphics.OrthographicCamera;
import com.badlogic.gdx.graphics.Texture;
import com.badlogic.gdx.maps.tiled.AtlasTmxMapLoader;
import com.badlogic.gdx.maps.tiled.TiledMap;
import com.badlogic.gdx.maps.tiled.TiledMapRenderer;
import com.badlogic.gdx.maps.tiled.TmxMapLoader;
import com.badlogic.gdx.maps.tiled.renderers.OrthogonalTiledMapRenderer;
import com.badlogic.gdx.scenes.scene2d.Stage;

public class Level extends ApplicationAdapter implements InputProcessor {
    ActorDemo jet;
    Stage stage;
    TiledMap tiledMap;
    OrthographicCamera camera;
    TiledMapRenderer tiledMapRenderer;
    AtlasTmxMapLoader test;

    @Override
    public void create () {
        float w = Gdx.graphics.getWidth();
        float h = Gdx.graphics.getHeight();
        jet = new ActorDemo();
        stage = new Stage();
        stage.addActor(jet);
        camera = new OrthographicCamera();
        camera.setToOrtho(false,w/2,h/2);
        camera.update();
        tiledMap = new TmxMapLoader().load("Level.tmx");
        tiledMapRenderer = new OrthogonalTiledMapRenderer(tiledMap);
        Gdx.input.setInputProcessor(this);
    }

    @Override
    public void render () {
        Gdx.gl.glClearColor(0, 0, 0, 0);
        Gdx.gl.glBlendFunc(GL20.GL_SRC_ALPHA, GL20.GL_ONE_MINUS_SRC_ALPHA);
        Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
        camera.update();

        tiledMapRenderer.setView(camera.combined,0,0,Gdx.graphics.getWidth(),Gdx.graphics.getHeight());
        tiledMapRenderer.render();
        stage.draw();
    }

    @Override
    public boolean keyDown(int keycode) {
        return false;
    }

    @Override
    public boolean keyUp(int keycode) {
        if(keycode == Input.Keys.LEFT)
            camera.translate(-32,0);
        if(Gdx.input.isKeyPressed(Input.Keys.A)){

            camera.position.x -=2;

        }
        if(keycode == Input.Keys.RIGHT)
            camera.translate(32,0);
        if(keycode == Input.Keys.UP)
            camera.translate(0,-32);
        if(keycode == Input.Keys.DOWN)
            camera.translate(0,32);
        if(keycode == Input.Keys.NUM_1)
            tiledMap.getLayers().get(0).setVisible(!tiledMap.getLayers().get(0).isVisible());
        if(keycode == Input.Keys.NUM_2)
            tiledMap.getLayers().get(1).setVisible(!tiledMap.getLayers().get(1).isVisible());
        return false;
    }

    @Override
    public boolean keyTyped(char character) {

        return false;
    }

    @Override
    public boolean touchDown(int screenX, int screenY, int pointer, int button) {
        return false;
    }

    @Override
    public boolean touchUp(int screenX, int screenY, int pointer, int button) {
        return false;
    }

    @Override
    public boolean touchDragged(int screenX, int screenY, int pointer) {
        return false;
    }

    @Override
    public boolean mouseMoved(int screenX, int screenY) {
        return false;
    }

    @Override
    public boolean scrolled(int amount) {
        return false;
    }
}

Here is where I put my tiled map

This is the tile set I used to create my tmx file

I added this tile set to to the tiled map editor and created a tile sheet and then put it in my project

This code works for me just fine, except without the jet actor and with my own map. Try the tilesheet from the tutorial. If you have any errors or output - please post it here — exenza
I did use the tilesheet used in the tutorial, and the same problem just a black screen, how did you use the tilesheet in the tutorial i may use it wrongly. thanks extenza for replying — Mahbadran
I just copy-pasted your code to my ide and changed the filename. How about keys up, down, right, left, num_1, num_2 do they change anything? — exenza
they don't change anything just a black screen and no responses to any input, did the code work with you ? — Mahbadran
Yes, it works. Could you please provide the whole file code? — exenza

It worked, the problem was that the program was not able to find the tile Set, so I changed the path(from the .tmx file) to where it actually located and it worked.
