Values
- enqueued → const TaskStatus
-
Task is enqueued on the native platform and waiting to start
It may wait for resources, or for an appropriate network to become available before starting the actual download and changing state to
running. - running → const TaskStatus
-
Task is running, i.e. actively downloading
- complete → const TaskStatus
-
Task has completed successfully
This is a final state
- notFound → const TaskStatus
-
Task has completed because the url was not found (Http status code 404)
This is a final state
- failed → const TaskStatus
-
Task has failed due to an exception
This is a final state
- canceled → const TaskStatus
-
Task has been canceled by the user or the system
This is a final state
- waitingToRetry → const TaskStatus
-
Task failed, and is now waiting to retry
The task is held in this state until the exponential backoff time for this retry has passed, and will then be rescheduled on the native platform, switching state to
enqueuedand thenrunning - paused → const TaskStatus
-
Task is in paused state and may be able to resume
To resume a paused Task, call
resumeTaskWithId. If the resume is possible, status will change to TaskStatus.running and continue from there. If resume fails (e.g. because the temp file with the partial download has been deleted by the operating system) status will switch to TaskStatus.failed
