3. Why Work Manager ?

4. Work Manager !!

5. Core Classes

6. Worker
class UploadWorker : Worker() {
override fun doWork(): Worker.WorkerResult {
// your work
return Worker.WorkerResult.SUCCESS
}
}

7. Constraints
val myConstraints = Constraints.Builder()
.setRequiresDeviceIdle(true)
.setRequiresCharging(true)
.build()

8. Work Request
val request = OneTimeWorkRequest.Builder(UploadWorker::class.java)
. .setConstraints(myConstraints)
.build()

9. Work Request
val request = PeriodicWorkRequest
.Builder(UploadWorker::class.java, 1, TimeUnit.HOURS)
.setConstraints(myConstraints)
.build()

10. Enqueue/Schedule Task :
WorkManager.getInstance().enqueue(request)

11. Behind the Hood?

12. Advanced Functionality
• Cancel Task -> WorkManager.getInstance().cancelWorkById(request)
• Chain Task -> Can chain multiple task to exectue using,
WorkManager.getInstance()
.beginWith(request)
.then(workB) // then() returns a new WorkContinuation instance
.then(workC)
.enqueue();
• Observer -> Work manager manages the LiveData of WorkStatus

13. When to Use Work Manager?
