Question

    Exception in th         


        

Answer 1

to see the code where it is called, but I venture to say that the problem is the call to your world this must be called before here's an example:

This a example compile good:

    oWorld = new World(gravedad, dormir);
    loader = new BodyEditorLoaderNewW(
             Gdx.files.internal("data/test.json"));

This a example not compile good:

    loader = new BodyEditorLoaderNewW(
             Gdx.files.internal("data/test.json"));
    oWorld = new World(gravedad, dormir);

recive this:

java.lang.UnsatisfiedLinkError: com.badlogic.gdx.physics.box2d.PolygonShape.newPolygonShape () J

note the difference in the world is called one after so gives:

it is possible that in the future can, need this: BodyEditorLoader - noSuchMethod

but if this is not the solution you could put some of the code, I hope you help

Answer 2

Based on this https://github.com/libgdx/libgdx/issues/2393 the problem is because natives aren't loaded before creating shape.

There are two solutions:

First is creating World instance before creating any shapes.

Second is calling Box2D.init(); before creating any shapes. This method is preferred because you don't need to create World instance and it's much more obvious.
