libGDX compiles only a Black Screen

Question

SOLVED!!! Seems the image wasnt in a proportionate size, eg, 64x64, 128x128

Made a basic Hello World and this compiled all good, but when I try and get a basic graphic to display, all that shows is blackness. basically following a tutorial word for word and it still seems to be doing this. Any ideas anyone?

package com.me.mygdxgame;

import com.badlogic.gdx.ApplicationListener;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.graphics.Color;
import com.badlogic.gdx.graphics.GL10;
import com.badlogic.gdx.graphics.OrthographicCamera;
import com.badlogic.gdx.graphics.Texture;
import com.badlogic.gdx.graphics.Texture.TextureFilter;
import com.badlogic.gdx.graphics.g2d.BitmapFont;
import com.badlogic.gdx.graphics.g2d.Sprite;
import com.badlogic.gdx.graphics.g2d.SpriteBatch;
import com.badlogic.gdx.graphics.g2d.TextureRegion;

public class MyGdxGame implements ApplicationListener {

SpriteBatch batch;
BitmapFont font;
Texture mario;





    @Override
    public void create() {
        mario = new Texture(Gdx.files.internal("mario.jpeg"));
        batch = new SpriteBatch();
        font = new BitmapFont();
        font.setColor(Color.CYAN);
    }

    @Override
    public void dispose() {
        batch.dispose();
        font.dispose();
    }

    @Override
    public void render() {      
        Gdx.gl.glClearColor(1, 1, 1, 1);
        Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);

        batch.begin();
        batch.draw(mario, 200, 200);
        batch.end();

    }

    @Override
    public void resize(int width, int height) {
    }

    @Override
    public void pause() {
    }

    @Override
    public void resume() {
    }
}

Just realised there was an error code coming up. file name is definitely correct.

It can't find the image "mario.png" in the data folder. Make sure you have the image in the android asset folder (Android Project -> Assets -> Data -> mario.png) .

You may want to look into how to read stack-traces (Big long error report thing) it will save you lots of time in the future.

Edit: Here is link for you on stack-traces

He couldn't find mario.png. I recommend, if you don't use an Assets folder, to create another source folder containing all of your resources. After that, you can call Gdx.input.classpath(String classpath) to load a file from the actual exported .jar, without having to hardcode the paths.
