LibGDX can't access internal image resources

问题

I clearly stored my "background.png" in the assets folder under android. I also checked that it was there in Finder.

I am working with Android Studio.

However, upon trying to access the image:

public Background() {
    textureRegion = new TextureRegion(new Texture("background.png"));
    textureRegionBounds1 = new Rectangle(0 - Constants.APP_WIDTH / 2, 0, Constants.APP_WIDTH, Constants.APP_HEIGHT);
    textureRegionBounds2 = new Rectangle(Constants.APP_WIDTH / 2, 0, Constants.APP_WIDTH, Constants.APP_HEIGHT);
}

I get this error:

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

What am I missing?

EDIT Also, my current path for the Desktop launcher for the Working Directory is : AndroidStudioProjects/libGDXGame

However, upon changing it to: AndroidStudioProjects/libGDXGame/android/assets

I get a new error like such:

回答1:

try using this:

textureRegion = new TextureRegion(new Texture(
                Gdx.files.internal("background.png")));

if it does not work review, case sensitive, of the file name.

Edit: look that is a copy of the file, not a link, once he happened to someone so wrong

回答2:

You shouldn't load assets in a constructor directly because Gdx.files is null. Either load the assets outside of the constructor or use the AssetsManager.
