Android JobScheduler Sample (Kotlin)

Demonstration of the JobScheduler API, which provides an interface for scheduling background tasks when certain tasks apply.

To understand how this sample works, try these different scenarios:

  • Unplug device, schedule a task that requires the device to be plugged in. Job will start when the device is plugged in.
  • Set a delay of 10 seconds and press back. The activity and service are finished but the service is launched again in 10 seconds (logcat will show debug messages).
  • Set a delay of 5 seconds and a work duration of 10 seconds. Schedule job and press the back button. Open the activity again after 6 seconds. The activity will show the onStopTask even though both activity and service were shut down.


  • Android SDK 27
  • Android Support Repository

Getting Started
