What should be considered when exchanging a significant amount of data between fragments using a Bundle object?

When passing large amounts of data between fragments via a Bundle object, consider:

• Size limitation: Bundle has a size limit (usually around 1 MB), exceeding which can lead to errors or crashes.
• Data serialization: All data must be serializable (e.g., Parcelable or Serializable) to be transmitted correctly.
• Performance: Transferring large data can slow down the app and increase fragment load times.
• Alternatives:
  • Use shared ViewModel with LiveData for data exchange between fragments.
  • Store data in a database or cache and pass only identifiers.

Example of passing small data via Bundle:

val bundle = Bundle().apply {
    putString("key", "value")
}
fragment.arguments = bundle

For larger data, it is better to use ViewModel or other mechanisms.
