Android Studio 4.1 Development Essentials – Kotlin Edition

By: Neil Smyth

Overview of this book

Android 11 has a ton of new capabilities. It comes up with three foci: a people-centric approach to communication, controls to let users quickly access and manage all of their smart devices, and privacy to give users more ways to control how data on devices is shared. This book starts off with the steps necessary to set up an Android development and testing environment, followed by an introduction to programming in Kotlin. An overview of Android Studio and its architecture is provided, 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 are also covered in detail. This edition of the book also covers printing, transitions, and cloud-based file storage; 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, Kotlin, and Android Jetpack.

70.10 Summary

Notifications provide a way for an app to deliver a message to the user when the app is not running, or is currently in the background. Notifications appear in the status bar and notification drawer. Local notifications are triggered on the device by the running app while remote notifications are initiated by a remote server and delivered to the device. Local notifications are created using the NotificationCompat.Builder class and issued using the NotificationManager service.

As demonstrated in this chapter, notifications can be configured to provide the user with options (such as launching an activity or saving a message) by making use of actions, intents and the PendingIntent class. Notification bundling provides a mechanism for grouping together notifications to provide an improved experience for apps that issue a greater number of notifications.
