Trouble loading .png file using LibGDX Gdx.files.internal

Question

I'm trying to load a Texture to libGDX and I'm getting a file not found exception.

Here's the code that's trying to load the .png file.

//Textures
private Texture tiles;
private TextureRegion grassImage;
private TextureRegion dirtImage;
private TextureRegion stoneImage;

//Entities
private Texture entities;
private TextureRegion playerImage;

public WorldRenderer(World world, boolean debug) {
    this.world = world;
    this.camera = new OrthographicCamera(CAMERA_WIDTH, CAMERA_HEIGHT);
    this.camera.position.set(CAMERA_WIDTH/2f, CAMERA_HEIGHT/2f, 0);
    this.camera.update();
    this.debug = debug;
    spriteBatch = new SpriteBatch();
    loadTextures();
}

public void loadTextures() {
    tiles = new Texture(Gdx.files.internal("tiles.png"));
    grassImage = new TextureRegion(tiles, 0, 0, 32, 32);
    dirtImage = new TextureRegion(tiles, 0, 64, 32, 32);
    stoneImage = new TextureRegion(tiles, 64, 0, 32, 32);

    entities = new Texture(Gdx.files.internal("entities.png"));
    playerImage = new TextureRegion(entities, 0, 0, 32, 32);
}

public void render() {
    spriteBatch.begin();
    drawGrass();
    drawDirt();
    drawStone();
    drawPlayer();
    spriteBatch.end();
    if (debug) {
        drawDebug();
    }
}

Here's the error message:

The problem exists in the loadTextures() method. Can't find the file

 tiles = new Texture(Gdx.files.internal("tiles.png"));

I've made sure to put the .png files in the assets folder of the android project files. I have no idea what's causing this; I've gotten this to work on other projects but this time around something went awry. Thanks for any help.

Answer 1

Solving the "Couldn't load file" issue by cleaning the project (Eclipse)

(For this solution is expected that the paths to your image files are correct.)

Sometimes I have this Couldn't load file problem when I add new images to my project. I don't know why, but my Desktop version of my LibGDX game doesn't update the folder Mygame-desktop/bin/data with my new images (which were added to Mygame-android/assets/data) when the project is built. (That is, every time I save a file, Eclipse builds the project, cause I set the option Project > Build Automatically.)

It should work, cause in LibGDX the Desktop and HTML projects have a link to the Android project assets folder. So, I was not suppose to need to copy manually my new images to Mygame-desktop/bin/data.

The solution, on Eclipse, is to clean (menu Project > Clean...) all LibGDX projects you use for your game, then the files in Mygame-android/assets/data will be copied to Mygame-desktop/bin/data properly.

If you're using Gradle, click the left mouse button in package explorer on Aassets -> Gradle -> Refresh All.

That's it =)

Answer 3

create new folder data in the assets folder of the android project and then access the file using Gdx.files.internal("data/tiles.png")

tiles = new Texture(Gdx.files.internal("data/tiles.png"));

Answer 4

Make a data folder in the assets folder and instead of using

tiles = new Texture(Gdx.files.internal("tiles.png"));

try this:

tiles = new Texture("data/tiles.png");
