App Inventor 2 Essentials

Overview of this book

App Inventor 2 will take you on a journey of mobile app development. We begin by introducing you to the functionalities of App Inventor and giving you an idea about the types of apps you can develop using it. We walk you through the technical set up so you can take advantage of the interactive development environment (live testing). You will get hands-on, practical experience building three different apps using tutorials. Along the way, you will learn computer science principles as well as tips to help you prepare for the creative process of building an app from scratch. By the end of the journey, you will learn how to package an app and deploy it to app markets. App Inventor 2 Essentials prepares you to amass a resource of skills, knowledge and experience to become a mobile app developer

We hope you found this chapter to be challenging yet rewarding. You have learned how to take a simple app and make it more intermediate by adding more complex features and code. Each feature, scoring, fling capability, and level requires a lot of thought on how each would work and interact with each other. As you experienced, enabling scoring and leveling mechanisms required us to alter code in a variety of block locations. Similarly, we had to reexamine how our buttons functioned and reprogram the buttons. You will discover that this is a typical process in coding. Changing or adding one thing requires reevaluating how other things would work and interact. Also, this chapter demonstrates how much thought needs to go into planning an app. Earlier in this chapter we decided to update our Label from Score to Score_Level_label to reflect that it would be displaying the Score, Level and Game Over.
