Overview of this book

For developers, Android 11 has a ton of new capabilities. The goal of this book is to teach the skills necessary to develop Android-based applications using the Java programming language. This book begins with the steps necessary to set up an Android development and testing environment. An overview of Android Studio along with the architecture of Android is covered next, followed by an in-depth look at the design of Android applications and user interfaces using the Android Studio environment. You will also learn about the Android architecture components along with some advanced topics such as touch screen handling, gesture recognition, the recording and playback of audio, app links, dynamic delivery, the AndroidStudio profiler, Gradle build configuration, and submitting apps to the Google Play Developer Console. The concepts of material design, including the use of floating action buttons, Snackbars, tabbed interfaces, card views, navigation drawers, and collapsing toolbars are a highlight of this book. This edition of the book also covers printing, transitions, and cloud-based file storage; the foldable device support is the cherry on the cake. By the end of this course, you will be able to develop Android 11 Apps using Android Studio 4.1, Java, and Android Jetpack.

81.1 About the Example App

The project used in this chapter is named AppLinking and is a basic app designed to allow users to find out information about landmarks in London. The app uses a SQLite database accessed through a standard Android content provider class. The app is provided with an existing database containing a set of records for some popular tourist attractions in London. In addition to the existing database entries, the app also lets the user add and delete landmark descriptions.

In its current form, the app allows the existing records to be searched and new records to be added and deleted.

The project consists of two activities named AppLinkingActivity and LandmarkActivity. AppLinkingActivity is the main activity launched at app startup. This activity allows the user to enter search criteria and to add additional records to the database. When a search locates a matching record, LandmarkActivity launches and displays the information for the related landmark.
