ChildLayer cl = new ChildLayer();
this.addChild(cl); ------------------------------>
}

public class ChildLayer extends CCLayer {

public ChildLayer() {
CCLayer.node();
}
.
.
}

Solution

  • This is solved.. In constructor,I have called the super class constructor like CCLayer.node() instead of super() I changed that and the problem is solved..
