Build native Android apps with Kotlin and Jetpack Compose
Android Development focuses on creating native applications for the Android operating system, which powers over 70% of mobile devices worldwide. As an Android developer, you will build apps using Kotlin (the modern, official language for Android), work with Android SDK, implement Material Design, handle background tasks, integrate with Google services, and optimize for various screen sizes and Android versions. This comprehensive roadmap covers Kotlin programming, Android fundamentals, Jetpack Compose (modern UI toolkit), architecture patterns (MVVM, Clean Architecture), Room database, Retrofit for networking, and advanced topics like WorkManager and Coroutines. Android developers are highly sought after by companies ranging from startups to tech giants. The role requires strong programming skills, understanding of Android lifecycle, attention to performance and battery optimization, and keeping up with Android's rapidly evolving ecosystem.
