How to persist nested Bundle in Android?

I have a Bundle with a nested nature that I want to pr开发者_如何学编程eserve, how can I persist the whole Bundle most easily? SharedPreferences lacks a bundle feature.

Don't use a Bundle. A Bundle is not meant to be persisted. Use a different data model (POJOs, HashMap, whatever) and write persistence logic (serialize, serialize to JSON, serialize to XML, write to SQLite, etc.).
