Trouble with JOGL and Visual Studio Code

I'm new to OpenGL in Java, and Java in general. I am following a textbook and trying to create my first window. However, when I run my code, I get the error that "package com.jogamp.opengl does not exist". I have added the .JAR files to my project's reference libraries as shown.
My code reads:
import javax.swing.*;
import static com.jogamp.opengl.GL4.*;
import com.jogamp.opengl.*;
import com.jogamp.opengl.awt.GLCanvas;
public class Code extends JFrame implements GLEventListener {
private GLCanvas myCanvas;
public Code() {
setTitle("Chapter 2 - program 1");
setSize(600, 400);
setLocation(200, 200);
myCanvas = new GLCanvas();
myCanvas.addGLEventListener(this);
this.add(myCanvas);
this.setVisible(true);
}
public void display(GLAutoDrawable drawable) {
GL4 gl = (GL4) GLContext.getCurrentGL();
gl.glClearColor(1.0f, 0.0f, 0.0f, 1.0f);
gl.glClear(GL_COLOR_BUFFER_BIT);
}
public static void main(String[] args) {
new Code();
}
public void init(GLAutoDrawable drawable) {
}
public void reshape(GLAutoDrawable drawable, int x, int y, int width, int height) {
}
public void dispose(GLAutoDrawable drawable) {
}
}
Any advice would be great - I'm guessing it is some simple step I've missed, but I've gone over the section in the book a couple of times now so I'm nto sure what I'm missing.

You have to add jogamp-fat.jar into the classpath. Please rather ask your JOGL specific questions on the official JogAmp forum as only a very few JOGL maintainers and users come on StackOverflow. Please ensure that you use at least JOGL 2.3.2. The namespace used in the JAR(s) must match with the namespace used in your source code above. Moreover, you must include the necessary JAR(s) not only when you compile but when you run your project too.
I don't know how VisualStudio Code works, these are the instructions for other major Java IDEs: https://jogamp.org/wiki/index.php?title=Setting_up_a_JogAmp_project_in_your_favorite_IDE

I am using Libgdx to build a mobile game. Can someone please show me how set the screen to one size?

package com.test.game;
import com.badlogic.gdx.Gdx;

import com.badlogic.gdx.graphics.g2d.SpriteBatch;
import com.badlogic.gdx.math.Rectangle;
import com.badlogic.gdx.math.Vector2;
public class Splash implements Screen {
private Sprite splash;
private SpriteBatch batch;
private float height = 1920;
private float width = 1080;
private float aspectratio = width/height;
#Override
public void render(float delta){
Gdx.gl.glClearColor(0,0,0,1);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
batch.begin();
splash.draw(batch);
batch.end();
}
#Override
public void resize(int width, int height){
}
#Override
public void show(){
batch = new SpriteBatch();
Texture splashTexture = new Texture("zeuswallpaperphone1.jpg");
splash = new Sprite(splashTexture);
//splash.setSize(Gdx.graphics.getWidth(), Gdx.graphics.getHeight());
splash.rotate(90);
splash.setPosition(Gdx.graphics.getWidth()/2 - splashTexture.getWidth()/2, Gdx.graphics.getHeight()/2 - splashTexture.getHeight()/2);
}

This is the splash screen of my game. I am trying to get the splash screen image to adjust for different screen sizes. Is there a way that I set the screen to one size? I want to set the screen to a size of 1280 x 720. And also will this keep the touch inputs the same? I do not understand why this is so hard in android. I have searched the internet vigorously trying to find a solution. I am also sorry if this question was already answered in another post. It seems that most answers to this problem are really old. I have not been able to find an answer the the problem that I have. I am looking for any help so please someone help me out. I have tried various methods and nothing seems to be working. Thank you in advance for your help. I hate that stack overflow makes you type a certain amount. There are a few libgdx tutorials out there. So if someone could watch one and get back to me that would be great. I have tried playing with the Viewport and Orthographic camera but when I run the game it will not adjust. On iOS you just set the screen size and you are good to go on all devices. They need that in android studio. Nothing seems to be working.
This is the code I have. Thanks for your help. This is crazy they still want me to type more.

I think you need to use a camera and viewport:
OrthographicCamera hudCamera = new OrthographicCamera();
Viewport hudViewport = new ScreenViewport(hudCamera);
public void create {
// Your code
hudViewport.apply(true);
}
public void render(float delta){
Gdx.gl.glClearColor(0,0,0,1);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
batch.setProjectionMatrix(hudCamera.combined);
batch.begin();
splash.draw(batch);
batch.end();
}
public void resize(int width, int height) {
hudViewport.update(width, height);
hudViewport.apply(true);
}
Make sure you are setting the correct size in your main method.

Exception in thread "LWJGL Application" com.badlogic.gdx.utils.GdxRuntimeException: Couldn't load file: badlogic.jpg

i'm begginer programmer and need some help. I'm using eclipse and libgdx. I created a project. When i try to load my file "background.png", i get this error:
"Exception in thread "LWJGL Application"
com.badlogic.gdx.utils.GdxRuntimeException: Couldn't load file:
badlogic.jpg"
. Oh wait, did you see that ? My file's name is "background.png", and error tells me that couldn't load "badlogic.jpg" I searched many forums but didnt find the solution cuz i think im the only one who is getting this error. And dont worry i have written my code correctly.`
This is GameScreen method
Reaction game;
OrthographicCamera camera;
SpriteBatch batch;
public GameScreen(Reaction game){
this.game = game;
camera=new OrthographicCamera();
camera.setToOrtho(true,1920,1080);
batch = new SpriteBatch();
}
#Override
public void show() {
}
#Override
public void render(float delta) {
Gdx.gl.glClearColor(0.95F, 0.95F, 0.95F, 0.95F);
Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
camera.update();
batch.setProjectionMatrix(camera.combined);
batch.begin();
batch.draw(Assets.sprite_back,0,0);
batch.end();
}
#Override
public void resize(int width, int height) {
}
#Override
public void pause() {
}
#Override
public void resume() {
}
#Override
public void hide() {
}
#Override
public void dispose() {
}
}
this is Assets method
public static Texture texture_back;
public static Sprite sprite_back;
public static void load(){
texture_back= new Texture(Gdx.files.internal("data/background.png"));
texture_back.setFilter(TextureFilter.Linear,TextureFilter.Linear);
sprite_back=new Sprite(texture_back);
sprite_back.setFlip(false, true);
}
}
and this is main game method
public GameScreen game_screen;
#Override
public void create() {
Assets.load();
game_screen = new GameScreen(this);
setScreen(game_screen);
}
}
I'm sure my code is correct cuz i made it with getting help from youtube videos. Please help me, im stuck...
More information: my files are linked, when i put my png file to assets/data folder it appears in desktop's assets too, and eclipse also automatically refresh files and when i manage files on eclipse, it happens to real project folder in my desktop, i tried to make it for you easier, i wish it helps.

Image not found in LibGDX

SOLVED, sorry!
I'm following this tutorial here: http://www.gamefromscratch.com/post/2013/10/02/LibGDX-Tutorial-3-Basic-graphics.aspx
For some reason, when running the code provided in that URL, an error comes back telling me that the image cannot be found, which is easily understandable. However, I cannot figure out why this error is coming at me.
Here is the error I am getting, just in case:

Here is the code:

public class MyGdxGame implements ApplicationListener {

#Override

texture = new Texture(Gdx.files.internal("data/jet.png"));
sprite = new Sprite(texture);
}
#Override
public void dispose() {

#Override
public void render() {

Here is my directory to the image:
C:\Android\projects\my-gdx-game-android\assets\data
Here is the directory in Eclipse:
So it looks like the image is not included in the project... How do I import it?

Refresh your project, right click over the project > Refresh or F5, so you can load the "jet.png" resource.
If you load the image directly on your Eclipse´s project explorer you will have no problems, but if you load only in Windows Explorer you have to refresh your project.

Solved using Import... -> File System -> Find my images and add them to the project.

First you can write this code
texture = new Texture(Gdx.files.internal("data/jet.png"));
like this (both right)
texture = new Texture("jet.png");
Second Make sure your file name dosn't have space before first letter (in asset folder)
cause reading " jet.png" is different from "jet.png"
Third Clean & refresh your project
Clean
1- Project ---> Clean
Refresh Gradle 2- Right Click ---> Cradle ---> Refresh All
Make sure you import files by drag and copy don't link it
your game desktop project ----> assets Drag your files & make sure you choose Copy

Libgdx tween not working on Android

I'm developing my first android game with libgdx, using as a base this amazing tutorial (http://www.kilobolt.com/day-11-supporting-iosandroid--splashscreen-menus-and-tweening.html). Everything works properly except for the tweening that I’m using in the splash screen to show the logo of my “company”. The weird part is that the logo works just fine in the desktop version, but in the android version is not being showed.
I’m using the same class that they used in the app developed in the tutorial. By the way, this app’s splash screen works fine in both versions.
I have compared my app and the tutorial’s app, but I found no differences except for this on the package explorer. I don't know if it means something:

import aurelienribon.tweenengine.BaseTween;

{
sprite = new Sprite(AssetLoader.logo);
sprite.setColor(1, 1, 1, 0);
float width = Gdx.graphics.getWidth();
float height = Gdx.graphics.getHeight();
float desiredWidth = width * .4f;
float scale = desiredWidth / sprite.getWidth();
sprite.setSize(sprite.getWidth() * scale, sprite.getHeight() * scale);
sprite.setPosition((width / 2) - (sprite.getWidth() / 2), (height / 2) - (sprite.getHeight() / 2));
setupTween();
batcher = new SpriteBatch();
}
private void setupTween()
{
Tween.registerAccessor(Sprite.class, new SpriteAccessor());
manager = new TweenManager();
TweenCallback cb = new TweenCallback()
{
#Override
public void onEvent(int type, BaseTween<?> source)
{
game.setScreen(new GameScreen());
}
};
Tween.to(sprite, SpriteAccessor.ALPHA, .8f).target(1).ease(TweenEquations.easeInOutQuad).repeatYoyo(1, .4f).setCallback(cb).setCallbackTriggers(TweenCallback.COMPLETE).start(manager);
}
#Override
public void render(float delta)
{
manager.update(delta);
Gdx.gl.glClearColor(1, 0, 0, 1);
Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
batcher.begin();
sprite.draw(batcher);
batcher.end();
}
}
Thank you very much for your help. I'm sorry if in any moment I couldn’t explain myself, but English is not my primary language. If you need any extra piece of code, I can add it.

You need to make sure you export the tween jar files in your Build Path. For Eclipse, you can Right-click on the project, choose "Build Path" > "Configure Build Path", go to the "Order and Export" tab on the right side, and make sure that the tween jar files are checked in the list there.
