App Inventor query

Question

I have a simple four button menu on my opening screen of my tentative road safety application on the App Inventor. What do I do with the 'screenName' and 'startValue' variables?

• The first button of my app directs you to a plain tips screen with numerous simple text tips in driving.
• The second button of the opening screen will give a searchable list of applicable fines to traffic violations. How do I implement these lists. Do I use an internal DB, fusion tables or Web DB?
• The third button button gives us a list of emergency numbers wherein I plan to use the MakePhoneCall() feature.
• The last one is a road sign quiz on the lines of the popular logo quiz. This is what it looks like :) http://oi58.tinypic.com/mb1xja.jpg

So, how do I implement the lists using the DB and how do I link screens or rather, the buttons to various screens?

Answer 1

For multiple screen apps, see the Manager Screen Demonstration and Tribblehunter's Multiple Screen Method.

For Working with lists, see here. Your data is static, which means, you could store it in global variables in lists and read it from there, in this case no database is necessary.

Btw, it also helps to do the tutorials first to learn the basics of App Inventor.
