I solved this(with above github Class/solution), but now I have issue below 

Java.lang.RuntimeException: Could not deserialize object. Class neuberfran.com.jfran.model.FireFranValue does not define a no-argument constructor. If you are using ProGuard, make sure these constructors are not stripped (found in field 'value')
