- A SwiftUI Charts TutorialThe objective of this chapter is to demonstrate the main features of the SwiftUI Charts in the form of a tutorial. Topics covered include creating a chart, displaying data from multiple data sources, and use of the style modifier. The concept behind the tutorial is a chart that displays monthly unit sales containing graphs for … Continue reading “A SwiftUI Charts Tutorial”
- An Overview of SwiftUI ChartsOne of the best ways to present data is to do so in the form of a chart or graph. While it has always been possible, given sufficient time and skills, to generate charts in SwiftUI by writing your own data handling and drawing code, it was not until the introduction of the SwiftUI Charts … Continue reading “An Overview of SwiftUI Charts”
- A SwiftUI NavigationStack TutorialThe previous chapter introduced the List, NavigationStack, and NavigationLink views and explained how these can be used to present a navigable and editable list of items to the user. This chapter will work through the creation of a project intended to provide a practical example of these concepts. About the ListNavDemo Project When completed, the … Continue reading “A SwiftUI NavigationStack Tutorial”
- SwiftUI NavigationStack and NavigationLink OverviewThe SwiftUI List view provides a way to present information to the user in the form of a vertical list of rows. Often the items within a list will navigate to another area of the app when tapped by the user. Behavior of this type is implemented in SwiftUI using the NavigationStack and NavigationLink components. … Continue reading “SwiftUI NavigationStack and NavigationLink Overview”
- A SwiftUI NavigationSplitView TutorialThe previous chapter introduced us to the SwiftUI NavigationSplitView component and described how multicolumn navigation is implemented and configured. This chapter will take what we have learned about NavigationSplitView and use it to create an example iOS app project. About the Project This tutorial will create the three-column split navigation app illustrated in the previous … Continue reading “A SwiftUI NavigationSplitView Tutorial”
- Multicolumn Navigation in SwiftUI with NavigationSplitViewThe NavigationStack and NavigationLink views outlined in the previous chapters are ideal for adding navigation when each destination view needs to fill the entire device screen. While this is generally the preferred navigation paradigm when working on most iOS devices, it doesn’t take advantage of larger display configurations available on the iPad or the iPhone … Continue reading “Multicolumn Navigation in SwiftUI with NavigationSplitView”
- A SwiftUI Grid and GridRow TutorialThe previous chapter introduced LazyHGrid, LazyVGrid, and GridItem views and explored how they can be used to create scrollable multicolumn layouts. While these views can handle large numbers of rows, they lack flexibility, particularly in grid cell arrangement and positioning. In this chapter, we will work with two grid layout views (Grid and GridRow) that … Continue reading “A SwiftUI Grid and GridRow Tutorial”
- A Jetpack Compose In-App Purchasing TutorialIn the previous chapter, we explored how to integrate in-app purchasing into an Android project and also looked at some code samples that can be used when working on your own projects. This chapter will put this theory into practice by creating an example project that demonstrates how to add a consumable in-app product to … Continue reading “A Jetpack Compose In-App Purchasing Tutorial”
- A Kotlin Android In-App Purchasing TutorialIn the previous chapter, we explored how to integrate in-app purchasing into an Android project and also looked at some code samples that can be used when working on your own projects. This chapter will put this theory into practice by creating an example project that demonstrates how to add a consumable in-app product to … Continue reading “A Kotlin Android In-App Purchasing Tutorial”
- How to Add Android In-App Billing using KotlinIn the early days of mobile applications for operating systems such as Android and iOS, the most common method for earning revenue was to charge an upfront fee to download and install the application. Another revenue opportunity was soon introduced in the form of embedding advertising within applications. Perhaps the most common and lucrative option … Continue reading “How to Add Android In-App Billing using Kotlin”
- Coroutines and LaunchedEffects in Jetpack ComposeWhen an Android application is first started, the runtime system creates a single thread in which all application components will run by default. This thread is generally referred to as the main thread. The primary role of the main thread is to handle the user interface in terms of event handling and interaction with views … Continue reading “Coroutines and LaunchedEffects in Jetpack Compose”
- A Jetpack Compose SharedFlow TutorialThe previous chapter introduced Kotlin flows and explored how these can be used to return multiple sequential values from within coroutine-based asynchronous code. In this tutorial, we will look at a more detailed flow implementation, this time using SharedFlow. The tutorial will also demonstrate how to ensure that flow collection responds correctly to an app … Continue reading “A Jetpack Compose SharedFlow Tutorial”
- Kotlin Flow with Jetpack ComposeThe earlier chapter titled “Coroutines and Side Effects in Jetpack Compose” taught us about Kotlin Coroutines and explained how they can be used to perform multiple tasks concurrently without blocking the main thread. A shortcoming of suspend functions is that they are typically only useful for performing tasks that either do not return a result … Continue reading “Kotlin Flow with Jetpack Compose”
- A Java Android In-App Purchasing TutorialIn the previous chapter, we explored how to integrate in-app purchasing into an Android project and also looked at some code samples that can be used when working on your own projects. This chapter will put this theory into practice by creating an example project that demonstrates how to add a consumable in-app product to … Continue reading “A Java Android In-App Purchasing Tutorial”

- Migrating from Material Design 2 to Material Design 3This chapter will demonstrate how to migrate an Android Studio project from Material Design 2 to Material Design 3 and integrate a custom theme generated using the Material Theme Builder tool. Creating the ThemeMigration Project Select the New Project option from the welcome screen and, within the resulting new project dialog, choose the Empty Activity … Continue reading “Migrating from Material Design 2 to Material Design 3”
- An Android Material Design 3 Theming and Dynamic Color TutorialThis chapter will show you how to create a new Material Design 3 theme using the Material Theme Builder tool and integrate it into an Android Studio project. The tutorial will also demonstrate how to add support for and test dynamic theme colors to an app. Creating the ThemeDemo Project Select the New Project option … Continue reading “An Android Material Design 3 Theming and Dynamic Color Tutorial”
- Working with Material Design 3 Theming in AndroidThe appearance of an Android app is intended to conform to a set of guidelines defined by Material Design. Material Design was developed by Google to provide a level of design consistency between different apps, while also allowing app developers to include their own branding in terms of color, typography, and shape choices (a concept … Continue reading “Working with Material Design 3 Theming in Android”
