Sommerhoff Peter. Instructor’s Manual for Kotlin for Android App Development

Addison-Wesley, 2019. — 84 p. — ISBN13: 978-0-13-558133-9.For the things we have to learn before we can do them, we learn by doing them. AristotleThis booklet can be used by instructors and students alike. Instructors can use it as in‐class exercises
or as assignments, and students can use these exercises for self‐organized learning. Example
solutions for all exercises can be found at the end of the booklet.
Of course, these represent just one way to solve an exercise. Many of the exercises in this booklet
are fairly open so that many different solutions are possible. The central point is that you try solving
them your way and gain programming experience with Kotlin.
You can solve these exercises in both Kotlin scratch files (.kts extension) and normal Kotlin files
(.kt extension) with a main function. But remember that some declarations, like sealed classes, don’t work well with scratch files.
The stars are an indicator for the difficulty of an exercise: more stars mean higher difficulty. Exercise
additions marked as “bonus” are typically a little harder than the original exercise.
