Difference between Serializable and Parcelable in Android

Serializable and Parcelable are both mechanisms used in Android for transferring data between different components such as activities, fragments, and services. Here are the key differences between Serializable and Parcelable:

1. Performance: Parcelable is considered to be more efficient in terms of performance compared to Serializable. This is because Parcelable uses a specialized mechanism for serialization and deserialization, resulting in faster data transfer.
2. Control over data: Parcelable provides more fine-grained control over the serialization and deserialization process. Developers can customize how their objects are serialized and deserialized using Parcelable, whereas Serializable is a more general-purpose mechanism with less control.
3. Compatibility: Serializable is a Java interface that can be used in any Java-based application, whereas Parcelable is specific to Android and is optimized for data transfer within the Android platform.

In conclusion, if you are looking for better performance and more control over the serialization process in Android, Parcelable is the preferred choice. However, if you need compatibility with non-Android applications, Serializable can still be used.
