I am newB in Android. I was working on a problem where I came across passing custom object between Activity. I did some research and found that, if I need to either implement Serializable or Parcellable interface, I also found that Parcellable is faster compared to Serializable. But I am having confusion on, let's say I have multiple custom Object in my class as property then do I need to make all those Object to implement either or those interface or there is any other method to do that.
Forgive me if I am not clear, please feel free to edit if possible.
Thanks.
The simplest way to use them would be to make your class implement Serializable, and make sure that every one of the class members also implement Serializable (or is a base value like int).
If you have a member that does not implement Serializable, you're going to have to implement the serialize/deserialize methods of our class manually.
Parcelable is more efficient, but not as automatic as Serializable.
