Android Studio 4.1 Development Essentials – Java Edition

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.

The first step is to implement the launchFeature() method, the purpose of which is to use an intent to launch the dynamic feature activity. Attempting to start an activity in a dynamic feature module that has yet to be installed, however, will cause the app to crash. The launchFeature() method, therefore, needs to include some defensive code to ensure that the dynamic feature has been installed. To achieve this, we need to create an instance of the SplitInstallManager class and call the getInstalledModules() method of that object to check whether the my_dynamic_feature module is already installed. If it is installed, the activity contained in the module can be safely launched, otherwise a message needs to be displayed to the user on the status TextView. Within the MainActivity.java file...
