What is the difference between Serializable and Parcelable Which is the best approach in Android?

Answer 1

"Typically, data must be transferred from one activity to another while designing apps. A related intent object has to include this data. To get the data ready for transfer, certain further steps are needed. The object needs to be parcelable or serializable to accomplish that.

Serializable:

• Serializable is a Java interface that is widely used. With this method, you merely implement the interface to designate a class as serializable, and Java will do the rest.

• The technique makes use of reflection, and numerous new things are produced. The result is the heavy rubbish collection and subpar performance.

Parcelable:

• An Android-specific interface is called Parcelable. You carry out the serialization by yourself in this method.

• Because reflection is not employed in this operation, no garbage is produced.

• Since Parcelable circumvents various issues with the built-in Java serialization mechanism, it is significantly more efficient than Serializable. It is also quicker and produces better - results because it has been tailored for use in the development of Android."
