I capitalized any product names that were incorrectly in lowercase. I also fixed any grammar, punctuation, and writing mechanics issues that I noticed.
The intent of this guide is to give you an idea about the Android development landscape and to help guide your learning if you are confused. Before we start, please note that the roadmap is opinionated, and you might have different opinions than those of the author. Having said that, [we would love to hear your opinions](https://github.com/kamranahmedse/developer-roadmap/issues/new) and incorporate them in the roadmap if suitable.
There are multiple ways to develop applications for the android; you can go down the path of hybrid application development where [flutter](https://flutter.dev/), [react-native](https://reactnative.dev/), or [NativeScript](https://www.nativescript.org/) are the most common contenders. Flutter uses Dart, whereas React Native and Native Script rely on JavaScript. Answering the question of hybrid vs native is out of the scope of this roadmap. This roadmap is focused on the native Android apps development but if you are interested in learning any hybrid framework, my personal preference is [react-native](https://reactnative.dev) and I would recommend you to checkout the [Frontend Developer Roadmap](/frontend).

## Pick a Language
For the languages, you can develop android apps either by using Kotlin or Java.
For the languages, you can develop Android apps either by using Kotlin or Java.
Although, you can use both [Kotlin](https://en.wikipedia.org/wiki/Kotlin_(programming_language)) and [Java](https://en.wikipedia.org/wiki/Java_(programming_language)) to develop native android apps, [Google announced in 2019](https://android-developers.googleblog.com/2019/05/google-io-2019-empowering-developers-to-build-experiences-on-Android-Play.html) to make Kotlin the preferred way of developing android applications. If you were to start learning android development today, Kotlin should be your language of choice.

Note: Android Studio comes with a working installation of Gradle, so you don’t need to install Gradle separately in that case.
## Version Control Systems
Version control systems record your changes to the codebase and allow you to recall specific versions later. There are multiple Version Control Systems available but [Git](https://git-scm.com/) is the most common one these days.

## Building an Application
Here is the list of items that you are going to need when developing Android applications. Please note that, this is an exhaustive list, and you don't need to know it all from the get-go. Get an idea of the items listed, and just start building some apps and keep the items listed in the back of your mind and have a deep dive when using them.

## Wrap Up
That wraps it up for the android developer roadmap. Again, remember to not be exhausted by the list; just learn the basics and start working on some project, rest of the learnings will come along the way. Good luck!
