This course explores the Kotlin language used in Android development.

If you've studied the basics of grammar, you'll naturally want to make something, right? This lecture helps novice C++ programmers become proficient in object-oriented programming while creating simple games. We provide the 'minimum' code that allows you to start game programming on your own and teach you the know-how of object-oriented programming that you could not have mastered just by studying grammar. Have fun creating and quickly jump to the intermediate level and beyond!

Currently, Android can be developed using the Java and Kotlin languages. The same Android application can be developed using either language. This course covers most of the content from basic to advanced Android application development, and all code is written using the Kotlin language starting from the basic content. We also use Material 3, Google's latest UI library. This course mainly covers menus, Android application components, threads, and Fragments among the entire Android curriculum, and future courses are planned to cover more in-depth topics. Soft Campus will always strive to provide the latest lectures. Thank you.
