How much money can an app make ?

It’s contextual and requires a lot of knowledge and experience because it totally depends on the business model, target users, revenue source, also it’s category like Gaming, Shopping, EdTech, Fintech, which matters a lot. So there are multiple factors affecting, including some external factors like user-base and competition. However, if your app idea is unique, user-friendly, and satisfies user’s needs they will love and it will eventually succeed. So, Never Give Up, and Believe in what You Build.

Before you start Android App Development with Kotlin, here’s what you need

  1.  Experience in a full-fledged object-oriented programming language such as Java, C++, or Smalltalk,
  2.  Familiar with all the concepts, tools, and vocabulary in Kotlin, if not you can take up Udacity’s free course to learn Kotlin basics here,
  3. The basic idea of what is Android Studio and Github, else just search YouTube there are a lot of beginner-friendly tutorials.

PS – if you’re trying Android Studio for the very first time I recommend to be very patient as setting up and working with it for the first time might take some time and fixes however do follow latest tutorials on youtube on how to set it up and running and it’s okay if you’re code breaks as you’ll learn new things everything will be okay.

The Kotlin Advantage

Unlike traditional Object Oriented languages like Java/ C++, you’re learning a new one just to develop apps only for android, so will learning Kotlin be worth the effort? Yes, totally.

  1. Less Boilerplate code, Less Code = More Productivity
  2. If you can code in Java then Kotlin is a piece of cake!
  3. Yes, Kotlin does support multiplatform development and backend too
  4. Language of the 20th century, launched in 2011 = easy to learn & safer code
  5.  According to Google, over 60% of the top 1000 apps on the Play Store use Kotlin

What is Google Codelabs

Codelabs were created by Google Developers they give a guided and tutorial like hands-on experience. Most codelabs will step you through the process of building a small application or adding a new feature to an existing application. So, basically there are codelabs on almost all Google technologies like cloud, flutter, and machine learning to help you learn the basics complete with solutions in GithHub, and yes all codelabs are available for free.
