i'm a beginner programmer and need some help. I'm using android studio and libgdx. I created a project. When I try to use box2d", I get this error:
"线程中的异常"；LWJGL应用"；com.badlogic.gdx.utils.GdxRuntimeException：java.lang.ExceptionInInitializerError">
Whenever I run a LibGDX project that uses box2d I always get a "java.lang.ExceptionInInitializerError" at the line where I initialize the world. I am just learning it in a tutorial series. I am trying to make am image into a physics body so it can fall. I think the problem may have something to do with the version of libGDX and android studio that I am using. Maybe both of them don't go too well. Please I would appreciate your help. Thank you.
public class MainGame extends ApplicationAdapter {
@Override
public void create() {
texture = new Texture("badlogic.jpg");
spriteBatch = new SpriteBatch();
sprite = new Sprite(texture);
world = new World(new Vector2(0, -98f),true);
body = createBody();
PolygonShape shape = new PolygonShape();
shape.setAsBox(sprite.getWidth()/2,sprite.getY()/2);
FixtureDef fixtureDef = new FixtureDef();
fixtureDef.density = 1f;
fixtureDef.shape = shape;
Fixture fixture = body.createFixture(fixtureDef);
shape.dispose();
}
}
当我运行程序时，我的logcat中的错误如下所示

如果您自己设置所有内容，则必须将gdx-box2d-nactives.jar添加到桌面项目的libs目录中。
相反，我建议您使用libGDX设置应用程序来创建一个包含所有依赖项设置和IDE集成的框架项目，然后您就可以在其中进行编程，而不必担心会摆弄库。
