25. Podcast Subscriptions, Part Two

Written by Fuad Kamal

Now that the user can subscribe to podcasts, it’s helpful to notify them when new episodes are available. In this chapter, you’ll update the app to periodically check for new episodes in the background and post a notification if any are found.

Getting started

If you’re following along with your own project, the starter project for this chapter includes an additional icon that you’ll need to complete the section. Open your project and then copy the following resources from the provided starter project into yours:

• src/main/res/drawable-hdpi/ic_episode_icon.png
• src/main/res/drawable-mdpi/ic_episode_icon.png
• src/main/res/drawable-xhdpi/ic_episode_icon.png
• src/main/res/drawable-xxhdpi/ic_episode_icon.png

When you’re done, the res\drawable folder in Android Studio will look like this:

If you don’t have your own project, don’t worry. Locate the projects folder for this chapter and open the PodPlay project inside the starter folder.

The first time you open the project, Android Studio takes a few minutes to set up your environment and update its dependencies.

Background methods

Checking for new episodes should happen automatically at regular intervals whether the app is running or not. There are several methods available for an application to perform tasks when it’s not running. It’s important to choose the correct one so that it doesn’t affect the performance of other running applications.

Alarms

You can use AlarmManager to wake up the app at a specified time so it can perform operations. An Intent is sent to the application to wake it up, and then it can perform the work.

Broadcasts

You can register to receive broadcasts from the system for certain events and then perform tasks. This option is highly restricted to a limited number of broadcasts in apps that target API level 26 or higher.

Services

Android provides foreground and background services.

Scheduled jobs

This is the approach Google recommends for most background operations. You can specify detailed criteria about when the job will run. Android intelligently determines the best time and takes advantage of system idle time.

WorkManager

WorkManager provides a way to schedule background tasks that are considered deferrable. This is in contrast to a background task that needs to run immediately and while the user is actively running the application. It also guarantees that the task will run even if the app is closed or the device is rebooted.

Episode update logic

To keep with the current architecture of using the repo for updating podcast data, you need to add a new method in the repo to handle the episode update logic.

Key Points

• JobScheduler is the recommended approach for adding background operations to your app.
• WorkManager is part of Android Jetpack. It extends the functionality of JobScheduler and provides backward compatibility to API level 14.
• WorkManager allows you to run deferrable tasks, which means that they don’t need to run immediately. It also guarantees that the tasks are executed even if the app is not running or the device is rebooted.
• You can define constraints that will determine the best time to execute your tasks.
• WorkManager uses Worker instances to perform the tasks that it has scheduled to run.

Where to go from here?

After testing, don’t forget to remove the temporary code you added to drop the first podcast when subscribing, and put back in the original repeat interval time.
