RestoreObserver

public abstract class RestoreObserver extends Object
Callback class for receiving progress reports during a restore operation. These methods will all be called on your application's main thread.

Fields Summary
Constructors Summary
Methods Summary
public voidonUpdate(int nowBeingRestored, java.lang.String currentPackage)
An indication of which package is being restored currently, out of the total number provided in the {@link #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.

param
nowBeingRestored The index, between 1 and the numPackages parameter to the {@link #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.
param
currentPackage The name of the package now being restored.

    
public voidrestoreFinished(int error)
The restore process has completed. This method will always be called, even if no individual package restore operations were attempted.

param
error Zero on success; a nonzero error code if the restore operation as a whole failed.

    
public voidrestoreSetsAvailable(android.app.backup.RestoreSet[] result)
Supply a list of the restore datasets available from the current transport. This method is invoked as a callback following the application's use of the {@link android.app.backup.IRestoreSession.getAvailableRestoreSets} method.

param
result An array of {@link android.app.backup.RestoreSet RestoreSet} objects describing all of the available datasets that are candidates for restoring to the current device. If no applicable datasets exist, {@code result} will be {@code null}.
hide

    
public voidrestoreStarting(int numPackages)
The restore operation has begun.

param
numPackages The total number of packages being processed in this restore operation.
