To transmit custom data between activities, implements Serializable or Parcelable interface is required.
You can use bundle putSerializable (String, Serizlizable) data or use intent putExtrr (String, Serizlizable) data directly.
I have a requirement to pass multiple custom data types, so I wrote a data class Value to encapsulate the custom data that I need. This class implements the Serizlizable interface. However, an error occurs during putExtra.

Later, I found that to transmit data between activities, all the content must implement the serializable interface, but a custom data encapsulated in my Value does not implement this interface, so an error occurs.
Then I set the custom type to implement the serializable interface.
