What is Android Development?
Android development is a software creation process that focuses on applications, better known as apps, that are compatible with devices running the Android operating system (OS). Because Android is an open-source project, developers have easy access to the Android software development kit (SDK). Many use this kit in conjunction with Kotlin, Java, and C++ programming languages to make their apps. The Android SDK tools compile your code along with any data and resource files into an APK, or Android package, which is an archive file that uses an .apk suffix. One APK file contains all Android app contents used by devices to install your app. When the app is complete and ready for release, Android developers can upload their apps to the Google Play Store for users to download.
What are some of the important tools for Android Development?
The tools you will use for Android development depend on how you would like to focus your career as an Android developer. If you plan on focusing on native Android app development, you should know one or more of three programming languages: Java, Kotlin, and C++. Java and Kotlin are popular with a number of organizations that build their app natively. C++ is the popular choice amongst developers who build high-performance games or plan on doing entry-level SDK work. Some employers seek out Android developers that can create multiple platforms at the same time using programming frameworks like Flutter or React Native. If you are working with Flutter, you will also need to know Dart. If you are working with React Native, you will most likely also need JavaScript programming knowledge.
Is Android Development a good career?
With over 2.5 billion active Android users globally, Android development is a valuable skill that can help you enhance your career. Android development skills are in-demand around the world with various organizations across a broad range of industries. When these organizations build Android apps natively, the top three programming languages are typically Java, Kotlin, and C++. You can also look for a job in Android development that uses cross-platform solutions like Flutter or React Native. Whether you're inspired to add a new language to your repertoire or prepare for an interview, you can find a ton of online resources on sites like OAK Academy to keep your Android skills well-rounded.
Is Kotlin or Java better for Android Development?
If you are building new Android apps, Kotlin is better suited because it is the recommended programming language for Android. If you are a first-time programmer, Kotlin android is also a better choice as it has safety features and concise syntax that will help you focus on learning core program fundamentals. You should note that in some cases, employers may seek out Android developers that have Java programming skills. For example, if you plan on joining an organization that already has an Android app, they may already be using Java. If they already have an app written in Java, it is unlikely they will want to redesign the app in a different language, such as android kotlin. Therefore, you should look at the job requirements to see if the job posting you are interested in lists Java as a required skill.
I really like the approach of this course about the Android app. It first teaches you Java which is highly important for designing apps in Android. Next, the instructor focuses on the Android SDK to teach you how to build beautiful applications for smartphones. As the course title indicates, it is the complete guide to learn android application development.
The Android platform is increasingly popular with developers and a dominant force in the global smartphone market. As more businesses develop mobile apps for customer engagement, Android development skills are likely to stay in high demand.

Took this particular course because the narrator was easy to understand. In Lesson 2, it switches to what appears to be an AI female voice with such terrible usages such as "$100,000" becoming "One hundred zero dollars US". Please STOP with the frickin' AI! It's not ready yet! I hope humans return to narrating this course, else I may not be able to finish it.

excellent course from start to finish, I learned to create applications on android with kotlin and java, I meet my expectations
By Fabien Lavoie on 11/21/2021
If you're looking for a course on actually writing code and making practical apps, this is not it. More of a demonstration of the Android Studio UI. Speech pacing is very annoying with long pauses between sentences. Makes it hard to speed up and slow down as needed.

this course, Android app development, is very up date. I would really appreciate some PDF Files with diagrams of some complex cods to make it a reference for the student while writing a code. For example how to code execute from point A to point Z to get the Info
