【问题描述】：
此代码在桌面上运行良好，但是当我在我的安卓手机上运行它时出现错误。 代码：
public class MainClass extends ApplicationAdapter {
private Stage stage;
private Skin skin;
@Override
public void create () {
skin=new Skin(Gdx.files.internal("uiskin.json"));
stage=new Stage(new ScreenViewport());
final Label label=new Label("This is a label",skin,"default");
label.setPosition(250,0);
label.setWidth(300);
label.setHeight(50);
stage.addActor(label);
Gdx.input.setInputProcessor(stage);
}
@Override
public void render () {
Gdx.gl.glClearColor(0.5f, 0.5f, 0.5f, 1);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
stage.act(Gdx.graphics.getDeltaTime());
stage.draw();
}
@Override
public void dispose() {
super.dispose();
stage.dispose();
skin.dispose();
}
}
错误：

我知道错误是因为手机找不到uiskin.json，但我不明白为什么。
