屏幕之间的libgdx切换非常慢，有时会崩溃而没有任何日志

Question

我正在使用libgdx来构建游戏，我使用了多个屏幕，并且它们之间的切换非常慢，有时会导致游戏崩溃，而无需在android设备上进行任何登录。我该如何解决这个问题？对于这个问题的原因，我完全一无所知。我在课堂上使用了几个动画和几个图像按钮，并使用了三个这样的类。

public class BabyGreen extends BabyScreen {


private BabyActor bg;
private BabyActor phone;
private AnimatedActor common;
private AnimatedActor plane,car,heli,boat,train,sub,truck,bus,police;
private ImageButton buttonLeft,buttonRight,buttonCenter;
private ImageButton 
button1,button2,button3,button4,button5,button6,button7,button8,button9;
private AnimatedActor actor;


public BabyGreen(Game g){
    super(g);
}

public void create () {


    bg = new BabyActor();
    bg.setTexture(new Texture("background-green.png"));
    bg.setSize(Gdx.graphics.getWidth(),Gdx.graphics.getHeight());


    phone = new BabyActor();
    phone.setTexture(new Texture("green-phone.png"));
    phone.setSize(Gdx.graphics.getWidth(),Gdx.graphics.getHeight());


    TextureRegion btLeft = new TextureRegion(new 
    Texture("ANIMALOFF.png"));

     stage.addActor(bg);
    stage.addActor(phone);


    Gdx.input.setInputProcessor(stage);
