Best Beginner Android Development Training

This is the best beginner Android development book you will find online. I know that is a bold claim so I stand to be corrected. The truth is,  Android development and programming, in general, is hard. What's even harder is learning to code in the first place. There is a seemingly endless amount of fundamental programming knowledge and concept to grasp before you even begin. As important as these fundamental knowledge are, it turns out no one gets paid for learning the fundamentals, you get paid for creating apps, for solving problems with this knowledge.

The challenge then in learning programming is how do you transition from learning the fundamentals to being a productive developer that is valuable in the marketplace. This is where many beginner programming books and courses fail. They either spend too much time teaching the fundamentals and bore the reader to death or they jump quickly into advanced concepts and make programming appear harder than it seems.

My approach is that beginner Android developers should hit the ground walking! If you hit the ground standing (just learning the fundamentals) you will be overwhelmed with too much head knowledge and could be discouraged. If you hit the ground running (jump into writing code) you could become a delusional programmer always struggling with the how never understanding the why.

Pronto Android is designed to help you make the transition from novice to proficient Android developer in 100 days. You will learn the basics of Object-Oriented Programming, along with a gradual introduction to Kotlin. With examples, you will be introduced to fundamental Android development concepts beginning from Activity, Fragment, Intents, and how your app interacts with other apps and services. 

From the beginning, you will start following modern Android development best practices using Android Architecture components such as LiveData, ViewModels, DataStore, Room Database to name a few. This training includes extensive hands-on experience using numerous Firebase components such as Authentication, Cloud Firestore, Storage, and others.

Become A Developer - One App A Week!

Learn by doing. Learn the fundamentals, the best practices and more importantly, write code.


Week 1: So You Want to Learn Android Development?

The first week will be focused on understanding the lay of the land in the world of Android development. You will learn about the tools, the terminologies, some historical context, and the structure of the training.

Week 4: Just Enough Kotlin

Kotlin is the official programming language for Android development and this training is based on Kotlin. This week we will be covering just enough Kotlin to get you started. While the remainder of the training is about learning Android development, in a sense it is also learning Kotlin. If you have the time-bandwidth or the need to learn standalone Kotlin first, by all means, step back and go and learn Kotlin and come back. But if you believe that you are capable of multi-tasking, or have a need to learn Android development in the short term, then follow along, you will learn Android development while greatly expanding your knowledge of Kotlin in the weeks to come.
