Android App Components: Fragments & Background Services

Master flexible UIs & build powerful background capabilities into Android apps, monitor your data streams & take action

What you'll learn

How to implement multiple code samples.

Learn how to send work requests to the background service.

Create layouts for multiple screens at runtime.

Perform long-running tasks using background services.

Master restrictions in using background services in Android Oreo along with workarounds such as using JobIntentService.

Deal with common problems and issues that might arise when using the services in your live projects.

Requirements

A basic understanding of Kotlin would be an added advantage but isn't mandatory.

Experience with background services will not be required.

Description

Are you willing to learn the basic functionality of how services and fragments work, build applications working in the background, by exposing you to using Android Background Service capabilities effectively? Then this course is for youThis hands-on course you will start by getting familiar with the fundamental concepts of fragments and adding fragments to an activity, fragment transactions & much more. Then you will get hands-on with the various kinds of services, threads, and processes, and their life cycle; then you'll move on to inter-process communication. Moving further you will learn to use IntentService, which utilizes a worker or background thread to execute tasks, explore what's new in the Background Service in Android Oreo and check out its limitations, and then overcome those limitations.Contents and OverviewThis training program includes 2 complete courses, carefully chosen to give you the most comprehensive training possible.The first course, Hands-On Android Application Components: Services and Fragments you will start by getting familiar with the fundamental concepts of fragments and adding fragments to an activity, fragment transactions, their lifecycle, and how they communicate with activities. You'll also explore fragment stability during screen rotation, and screen sizes. Then you will learn about services, another application component that will continue to run in the background even if the user switches to another application. Here you will get hands-on with the various kinds of services, threads, and processes, and their life cycle; then you'll move on to inter-process communication. Lastly, you will implement everything you've learned and built a TODO application; you'll learn to pass and manage arguments and master the communication flow between services and fragments in multiple ways. By the end of this course, you'll have a very strong foundation in Android fragments and Android services.The second course, Hands-on Background Services in Android you will learn a variety of topics like starting and stopping your service, interacting with the background service and creating and sending a work request, exploring the lifecycle of your service along with understanding the security issues in using it. You will learn to use IntentService, which utilizes a worker or background thread to execute tasks. You will explore what's new in the Background Service in Android Oreo and check out its limitations, and then overcome those limitations. You will then learn the best practices and how to deal with problems and issues that might arise. By the end of the course, you will have a strong foundation in background services in Android and will be able to build the functionality you need to ensure you won't drain the battery excessively, compromise the user's security, consume too much data, or hamper the device's performance.About the Authors:Mona Vafa is an energetic mobile developer with 4+ years' robust code experience in Java-Android and iOS.
