I got this error too, and find someone's suggestion in this forum Just type below code to FriendlyMessage.java under Public Class FriendlyMessage : **public FriendlyMessage() {}** It solved my problem

@prince-28 have u succeeded to add messages node/child to your database? If yes maybe you can add one line code to your FriendlyMessage.java (under public class FriendlyMessage): **public FriendlyMessage() {}**
