 The plugin runs on ios 10.0 and above and internally uses [AFNetworking](https://github.com/AFNetworking/AFNetworking). AFNetworking uses [NSURLSession](https://developer.apple.com/library/content/documentation/Cocoa/Conceptual/URLLoadingSystem/Articles/UsingNSURLSession.html#//apple_ref/doc/uid/TP40013509-SW44) under the hood to perform the upload in a background session. When an upload is initiated, it will continue until it has been completed successfully or until the user kills the application. If the application is terminated by the OS, the uploads will still continue. When the user relaunches the application, after calling the init method, events will be emitted with the ids of these uploads. If the user kills the application by swiping it up from the multitasking pane, the uploads will not be continued. Upload tasks in background sessions are automatically retried by the URL loading system after network errors as decided by the OS.
 
 ## Android
-The minimum API level required is 21 and the background file upload is handled by the WorkMananger library. If you have configured a notification to appear in the notifications area, the uploads will continue even if the user kills the app manually. If an upload is added when there is no network connection, it will be retried as soon as the network becomes reachable unless the app has already been killed.

 On Android 12 and above, there are strict limitations on background services that does not allow to start a Foreground Service when the app is processing in background(https://developer.android.com/guide/components/foreground-services). Hence to prevent this on Android 12 and above, we have a classic notification. On Android 11 and below, we are still using foreground service along with WorkManager to start the notification.
