Introduction

You have now learned the basics of Android app development and implemented features such as RecyclerViews, notifications, fetching data from web services, and services.

Now, you will be learning about background operations and data manipulation.

Some Android applications work on their own. However, most apps would need a backend server to retrieve or process data. These operations may take a while, depending on the internet connection, device settings, and server specifications. If long-running operations are run in the main UI thread, the application will be blocked until the tasks are completed.
