Using WorkManager to manage background tasks - free course from AndroidSchool.ru, training 2 hours, Date November 28, 2023.

At every stage of development of the Android operating system, there were different ways to work with background tasks, including when the application is “killed” by the operating system - but some kind of task must be running in the background logics. For example JobScheduler, GCM Network Manager, FirebaseJobDispatcher or Android Job by Evernote. And at Google I/O 2018, Google announced the WorkManager library, which is the recommended way to manage tasks that must be performed on a non-UI thread, even when the user is no longer actively interacting with application.

Tasks effectively solved using WorkManager:

• Execute network requests at specified intervals
• Clearing the database cache once a day
• Updating information for widgets
• Sequential execution of background tasks
• Downloading heavy files
• User geolocation tracking

As you can see, the areas of application of WorkManager are very diverse and that is why we will look at practical examples of how to manage such tasks through WorkManager. In this course you will learn how to work with the WorkManager library, learn how to launch different types of workers to perform background tasks.

• Types of tasks OneTimeWorkRequest and PeriodicWorkRequest
• Working with RxWorker
• Methods for obtaining geolocation through FusedLocationProviderClient
