Question

I have the following class definition:

public class Message {
     private String sender, text;

     public Message(String sender, String text) {
         this.sender = sender;
         this.text = text;
     }

}

I would like to be able to send an instance of this Message class over a bluetooth socket. In order to do this, it will need to be converted into a byte[]. After it has been sent, I need to convert it back to a Message object (on the other side of the socket). How can I achieve this?

Answer 1

Two possible answers
Serializable vs Parcelable

Serializable relatively easy to implement but not efficient in term of memory and CPU

Parcelable more complex to implement but more efficient in term of memory and CPU
