Android Development Roadmap



ANDROID DEVELOPMENT ROADMAP



The Android ecosystem is in a constant state of growth: Every day, new libraries and materials are introduced that are designed to accelerate development speed and make our lives as developers easier.

In this, you’ll learn all about the Android development ecosystem following our Android Developer Roadmap, giving you a more holistic view of the Android community and how you can progress as a developer.


The Android Developer Roadmap is designed to give you a comprehensive understanding of the current Android ecosystem and provides suggested learning paths along the way to help you grasp the concepts.



  1. Choose Language:


In Android, programming is done in two languages JAVA or Kotlin and XML(Extension

Markup Language). The XML file deals with the design, presentation, layouts, blueprint, etc (as a front-end) while the JAVA or KOTLIN deals with the working of buttons, variables, Storing, etc (as a back-end). And the biggest confusion for an Android beginner is which language to choose between Java and Kotlin?


2. Android Studio


It’s better to know your tools before you are going to use them. Android Studio is the official Integrated Development Environment for Google’s Android operating system, built on JetBrains’ IntelliJ IDEA software and designed specifically for Android development.


3. Android Components


There are some necessary building blocks that an Android application consists of. These loosely coupled components are bound by the application manifest file which contains a description of each component and how they interact.


Activity:


Activity life cycle

Handle Activity State Changes

Understand Tasks and Back Stack

Processes and Application Lifecycle


Services:
