As an example, let's implement a simple logging function:

JSObject logger = (JSObject)ctx.get("{}"); logger.set("log", new
JSFunction(){

     public void apply(JSObject self, Object[] args) {
       String msg = (String)args[0];
       Log.p("[Javascript Logger] "+msg);
     }
 });

 ctx.set("window.logger", logger);


 c.executeAndReturnString("logger.log('This is a test message');");
