Android Fundamentals for Beginners (Philipp Lackner)

Philipp Lackner walks through Android app development with Kotlin, starting with setup, a tour of Android Studio, activities and their lifecycle, and fixing common Android Studio errors. Lessons cover layout basics with LinearLayout and ConstraintLayout including chains and guidelines, then buttons, TextViews, EditTexts, ImageViews, checkboxes and radio buttons, toasts and context, starting activities with intents and passing data between them. It suits learners who know basic Kotlin. Afterwards, move on to Jetpack Compose and app architecture.
