About Android Development
Android development is the craft of building apps for the world's most widely used
mobile operating system, and this course walks through it in the order most
developers actually learn it. It starts with Android Basics & Studio
Setup, then Kotlin Fundamentals and
Version Control & Repo Hosting so you can write and track real
code.
Next comes UI with Jetpack Compose: building screens declaratively
with layouts, Material 3, and lists. From there,
App Architecture covers ViewModel, MVVM, and Hilt, while
Navigation & State covers moving between screens and keeping
state alive across rotation and process death.
Local Data & Storage covers Room and DataStore, and
Networking & APIs covers Retrofit, JSON parsing, and handling
loading and error states in the UI.
Finally, Testing & Debugging covers unit tests, UI tests, Logcat,
and profiling, and Publishing & Play Store covers signing a
release bundle and shipping through Play Console: the skills that separate a demo
from an app people can actually install.

What You Can Do After This Course
By the end of the curriculum you'll have worked through 5 hands-on projects and
covered the core of what a junior Android role expects. Concretely,
you'll be able to:
Set up and run an Android project: use Android Studio, Gradle, and emulators or a real device with confidence.
Write and version real Kotlin: use null safety, collections, and coroutines, tracked with Git and shared through GitHub or GitLab.
Build modern UIs: create responsive screens with Jetpack Compose and Material 3.
Structure an app properly: apply ViewModel, MVVM, and dependency injection so code stays testable and easy to change.
Store and fetch data: persist data with Room and DataStore, and consume REST APIs with Retrofit.
Test and debug: write unit and UI tests, and track down crashes and slow screens with Logcat and the profiler.
Ship to the Play Store: sign a release bundle and publish your app through Play Console.
