What is the difference between Serializable and Parcelable in Android, and when would you use one over the other?

Serializable vs Parcelable in Android

Serializable and Parcelable are two ways to serialize and deserialize objects in Android. The main difference between Serializable and Parcelable is their performance. Parcelable is faster and more efficient than Serializable.

When to use Serializable:

• Use Serializable when you simply want to serialize an object without worrying about performance.
• Serializable is easier to implement as it only requires adding 'implements Serializable' to your class.
• Serializable is useful for simple data structures and small datasets.

When to use Parcelable:

• Use Parcelable when you need to pass data between Android components frequently, such as between Activities or Fragments.
• Parcelable is faster and more efficient than Serializable, making it suitable for high-performance applications.
• Parcelable requires more effort to implement as you need to write custom serialization and deserialization code for each class.

In summary, choose Serializable for simpler use cases and ease of implementation, while Parcelable is recommended for performance-critical scenarios when passing data between components frequently in Android applications.
