LIBGDX - 纹理故障

Question

I'm playing around with LIBGDX in Android Studio and I'm trying to insert an image as a texture for my game. I'm using the "badlogic.jpg" that is included for example. The image shows up fine on DesktopLauncher and on my Nexus 7 but on my Samsung Galaxy Note 3, something is wrong. I hope these screenshots explain better: Samsung - Nexus 7

This is my GameRenderer class in case that helps:

    public class GameRenderer {

    public static Texture badLogic;
    private SpriteBatch batch;

    private GameWorld myWorld;

    private OrthographicCamera cam;

    public GameRenderer(GameWorld world) {
        myWorld = world;

        cam = new OrthographicCamera();
        cam.setToOrtho(true, 1920, 1080);

        batch = new SpriteBatch();

        badLogic = AssetLoader.badLogic;


    }

    public void render(float runTime) {

        batch.begin();
        batch.draw(badLogic, 100, 100);
        batch.end();

    }

}

And GameScreen:

public class GameScreen implements Screen {

private GameWorld world;
private GameRenderer renderer;
private float runTime;

public GameScreen() {

    world = new GameWorld();
    renderer = new GameRenderer(world);

}
@Override
public void show() {

}

@Override
public void render(float delta) {               
    Gdx.app.log("FPS:", (1 / delta) + "");
    runTime += delta;
    world.update(delta);
    renderer.render(runTime);

}

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

}

@Override
public void pause() {

}

@Override
public void resume() {

}

@Override
public void hide() {

}

@Override
public void dispose() {

}

}

Is this even an issue with the code or is it my device?

Answer 1

The problem is that you have made your Texture static

     public static Texture badLogic;

it should be

     public Texture badLogic;

Android has issues with unloading static content after end of application life cycle and that's why you see these glitches

Answer 2

Solved by adding Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);

to this part in the GameRenderer:

    public void render (float runTime) {
        Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
        batch.begin();
        batch.draw(badLogic, 0, 0);
        batch.end();
    }
