Invalid float: "2.0:" on Android 4.0.4

Troubleshooting android
1

Hello Everybody!

I tried to deploy the simplest application on Android 4.0.4
Application’s source is
[java]
public class Main extends SimpleApplication {

public static void main(String[] args) {
    Main app = new Main();
    app.start();
}

@Override
public void simpleInitApp() {
    Box b = new Box(1, 1, 1);
    Geometry geom = new Geometry("Box", b);

    Material mat = new Material(assetManager, "Common/MatDefs/Misc/Unshaded.j3md");
    mat.setColor("Color", ColorRGBA.Blue);
    geom.setMaterial(mat);

    rootNode.attachChild(geom);
}

@Override
public void simpleUpdate(float tpf) {
    //TODO: add update code
}

@Override
public void simpleRender(RenderManager rm) {
    //TODO: add render code
}

}
[/java]

I have done everything like in the instruction described

I have the latest (nightly) jme3’s version. Nonetheless I have got an error. How could I fix the next one?

It’s a known issue of RC2, you have to use the svn in order to have it fixed
