- data
- A structured wrapper around an open, read-only file descriptor pointing to a full snapshot of the application's data. The application should consume every entity represented in this data stream.
- appVersionCode
- The value of the android:versionCode manifest attribute, from the application that backed up this particular data set. This makes it possible for an application's agent to distinguish among any possible older data versions when asked to perform the restore operation.
- newState
- An open, read/write ParcelFileDescriptor pointing to an empty file. The application should record the final backup state here after restoring its data from the data stream. When a full-backup dataset is being restored, this will be null.
Type Reason Java.IO.IOException
Run the restore process on each of the configured handlers.
