3. Background Processing Why do we need it? 1
4. Background Processing ◉ Android has main thread, which handles UI & user interaction. ◉ Too much process on main thread = lag / froze even forced close. ◉ Solution #1 Background thread = move the processing in background while the app is active. ◉ Solution #2 Background process = move the processing in background even though the app is not active.
5. Type of Background Processing - Service - Job Scheduler - Alarm Manager - Foreground Service - WorkManager
6. - It was great until API level 26. - https://developer.android.com/guide/compon ents/services Service
7. Foreground Service - Service but run in Foreground. - Shows unclearable notification. Place your screenshot here

10. WorkManager And how to use it. 2
11. WorkManager - Part of Android Jetpack. - Backwards compatible (~ API 14). - Uses JobScheduler on API 23+. - Uses a combination of AlarmManager & BroadcastReceiver on API 14-22. - Ensures task execution, even if the app or device restarts.
12. WorkManager - Schedule one time task or periodic tasks. - Constraints. - Chaining. - Manage & monitor scheduled tasks. - Works with or without Play Services. - Adhere to system best practices. - LiveData support.
13. Constraints - Network connection. - Charging. - Battery level. - Storage size. - Device’s idle status.
14. Chaining - Multiple requests can run in sequence. - A request output become next request’s input. Request #1 Get Location Request #2 Send to Server Request #2 Check Location
15. Case for WorkManager - Sending logs / analytics / data to server. - Periodically update user location. - Sync data with server. - Create local notification after certain time has passed.
16. WorkManager APIs Worker This is where you put the actual work to be executed. You’ll extend this class and override the doWork() method.
17. WorkManager APIs WorkRequest Represents the request to do the work. It consists of OneTimeWorkRequest and PeriodicWorkRequest. You passed in a Worker to create a WorkRequest. You can also set the Constraints or a Delay.
18. WorkManager APIs WorkManager Schedules your requests and run them.
