How to Pass a Serializable List of Objects via Intent in Android?

Passing Objects with Serializable

In this query, the user is encountering difficulties in transferring a serializable class via an intent. Despite implementing Serializable, the operation remains unsuccessful.

The class involved, Thumbnail, contains attributes and methods for managing labels and bitmaps. The user attempted to send a list of these Thumbnail objects via intent, but without success.

To resolve this issue, it is not necessary to use Parcelable. Instead, the user can pass the serializable list using a Bundle.Serializable within the intent.

Bundle bundle = new Bundle();
bundle.putSerializable("value", all_thumbs);
intent.putExtras(bundle);

On the receiving end, within the SomeClass Activity:

Intent intent = this.getIntent();
Bundle bundle = intent.getExtras();

List<Thumbnail> thumbs = (List<Thumbnail>) bundle.getSerializable("value");

This approach enables successful data transfer of the Thumbnail object list via intent using Serializable.
