You can think of bundles as persistable dictionaries.
The primary use of a bundle is to save the state of an activity in onSaveInstanceState(Bundle) so you can restore the activity again in onCreate(Bundle).
The secondary use of a bundle (when put inside a message) is in asynchronous and/or inter-process communication.

A Bundle is a HashTable or Map, if you know the terms from other languagens.
Is basically a array, where you define something to be the index (could be a string) and something to be the data.
If you set two datas on the same index, the second will overwrite the first.
Do the notepad tutorial( Notepad Tutorial | Android Developers ), there you will learn how to work with bundles.
