Users are expected to Register a call back ImportProcessor by calling ImportService.registerObserver(ScanObserver) method.It maintains a hash for each directory to be imported. The value of hash for each directory is determined by (immediate filename+size+lasModifiedTime). Addition/Changes are commited after each directory or max 100 photos

IllegalStateException - if instance of importProcessor is not registered

initService

protected void initService(ImportContext importContext,
                           ImportProgressObject importProgressObject)

startImporterThread

protected ImportProgressObject startImporterThread(ImportContext importContext,
                                                   ImportProgressObject importProgressObject)
