Chapter 15. Handling Data and Generating Random Numbers
We are making good progress. We have a rounded knowledge of both the Android UI options and the basics of Kotlin. In the previous few chapters, we started bringing these two areas together and we manipulated the UI, including some new widgets, using Kotlin code. However, while building the Note to self app, we have stumbled upon a couple of blanks in our knowledge. In this chapter, we will fill in the first of these blanks, and then, in the next chapter, we will use this new information to progress with the app. We currently have no way of managing large amounts of related data. Aside from declaring, initializing, and managing dozens, hundreds, or even thousands of properties or instances, how will we let the users of our app have more than one note? We will also take a quick diversion to learn about random numbers.
We will cover the following topics in this chapter:
- Random numbers
- Arrays
- A simple array mini-app
- A dynamic array...
