Public methods
onUpdate
open fun onUpdate(
nowBeingRestored: Int,
currentPackage: String!
): Unit
An indication of which package is being restored currently, out of the total number provided in the restoreStarting(int) callback. This method is not guaranteed to be called: if the transport is unable to obtain data for one or more of the requested packages, no onUpdate() call will occur for those packages.
| Parameters | |
|---|---|
| nowBeingRestored | Int: The index, between 1 and the numPackages parameter to the restoreStarting(int)callback, of the package now being restored. This may be non-monotonic; it is intended purely as a rough indication of the backup manager's progress through the overall restore process. | 
| currentPackage | String!: The name of the package now being restored. | 
restoreFinished
open fun restoreFinished(error: Int): Unit
The restore process has completed. This method will always be called, even if no individual package restore operations were attempted.
| Parameters | |
|---|---|
| error | Int: Zero on success; a nonzero error code if the restore operation as a whole failed. | 
restoreStarting
open fun restoreStarting(numPackages: Int): Unit
The restore operation has begun.
| Parameters | |
|---|---|
| numPackages | Int: The total number of packages being processed in this restore operation. |
