    Firebase requires your Pojo to have public getters and setters, check if you created getters and setters and if your variables are public!

    Firebase Database considers public fields and JavaBean-like getters and setters when serializing/deserializing JSON. A public field with a getter and a setter may cause this exception. Try to change to private or removing getter and setter.
