Question

I want to pass objects between Activities and Services on Android. The straight forward way to do this is to make your objects implement Serializable or Parcelable.

• Serializable it’s relatively bad performance.
• Parcelable on the other hand requires me to implement and maintain the serialization myself i.e. always to remember to update it in the future.

I was thinking about using Jackson Json serializer for this task.
It’s faster than Java built in serialization and does not require me write and maintain serializtion code.

What you think?

Answer 1

If performance is important, then you really should go with Parcelable. JSON will be relatively slow because it is less efficient than Parcelable which was specifically implemented in Android for improving performance when packaging data for Inter-Process Communication.
