How to design an android application tutorial?

Question

Android

I am writing a tutorial consisting of 50 lessons, each lesson is a text and several audio files, and the location of the text and audio files in each lesson is different, it is also necessary to highlight some words in the text and play sound when clicked, I found only spannableString from the solutions, since the webview has restrictions.

1. How to implement everything correctly to create 50 activities or fragments? or dynamically form it all in one activity?
   
2. What to choose to store json or sqlite text?
   

Answer 1

50 Manual creation of activities is a nightmare, the best solution is to dynamically create all these lessons.
