How to organize and what to use to display large text and many pictures?

Question

Android

I am writing an application that has an activity that displays a lot of text and a lot of pictures:
1. What to use to display text?
2. What to use to display pictures?
3. Where is this data stored? In the database, etc.
4. What is the best way to organize?
For example, there is an AndroidTutorials application, where does it store pictures and in what form? How does it display text? And how does he store this text?
