`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.

onUpdate

Added in API level 8

void onUpdate (int nowBeingRestored, 
                String currentPackage)

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

Added in API level 8

void restoreFinished (int error)

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

Added in API level 8

void restoreStarting (int numPackages)

The restore operation has begun.

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