Android Studio 4.1 Development Essentials – Java Edition

By: Neil Smyth

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.

Split-screen mode can be entered by displaying the Overview screen, pressing and holding the app icon in the toolbar of a listed app and selecting the Split screen menu option as indicated in Figure 64-5:

Figure 64-5

Once in split-screen mode, the Overview button will change to display two rectangles (marked A in Figure 64-6), the current activity will fill part of the screen (B) and the Overview screen will appear in the adjacent part of the screen allowing the second activity to be selected for display (C):

Figure 64-6

Once the second app has been selected, the screen will be split evenly as illustrated previously in Figure 64-1 above.

To exit split-screen mode, simply drag the divider separating the two activities to a far edge so that only one activity fills the screen, or press and hold the Overview button until it reverts to a single square.
