# Basic Background Task (Save on Suspend)

## Goal

When the app is being suspended, start background allowance, save quickly, then end the task.

## Actions used

* `TaskServicesStartTaskAndAllowInBackground`
* `TaskServicesCancelTask`

## Variables

* `taskId` (String) (optional)

## Flow

1. State: `OnApplicationPause(true)` (or your “app suspending” trigger)
   * Go to `StartBackgroundAllowance`.
2. State: `StartBackgroundAllowance`
   * Action: `TaskServicesStartTaskAndAllowInBackground`
   * Save `taskId` output (optional).
   * Events:
     * `startedEvent` → `DoSave`
     * `failureEvent` → `DoSave` (fallback: still try a minimal save)
3. State: `DoSave`
   * Do your save work (keep it short on iOS).
   * Then go to `EndBackgroundAllowance`.
4. State: `EndBackgroundAllowance`
   * Action: `TaskServicesCancelTask`
   * Input: `taskId` (or leave empty to use `TaskServicesUtils.LastTaskId`)

## Notes

* Assign `quotaWillExpireEvent` on `TaskServicesStartTaskAndAllowInBackground` and add it as a Global Transition if you need an emergency “save minimal” path (see Use Case 2).
