A comprehensive, modern guide to building Android applications — the apps that run on billions of phones, tablets, watches, and TVs.

Welcome to Android Application Development: From First App to Professional.

A comprehensive, modern guide to building Android applications — the apps that run on billions of phones, tablets, watches, and TVs. It teaches the contemporary Android stack: Kotlin, declarative UI with Jetpack Compose, sound app architecture (MVVM / Clean), coroutines and Flow for concurrency, local data with Room, networking with Retrofit, dependency injection with Hilt, background work, testing, and publishing on Google Play — carrying you from your first screen to the skills of a working professional.

This title is part of the ShriIra library and is free to read in full, right here — our small contribution to making world-class knowledge easy to reach.
