Public Methods

public void onUpdate (int nowBeingRestored, String currentPackage)

Added in API level 8

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.

public void restoreFinished (int error)

Added in API level 8

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.

public void restoreStarting (int numPackages)

Added in API level 8

The restore operation has begun.

Parameters
numPackages int: The total number of packages being processed in this restore operation.
