Drop The Box App
Android 4.4 now can directly open and save files stored in cloud-based systems like Box. This eliminates the need to use one app for opening files on Box, another for Dropbox, and so on. It also works with files created or saved in Quickoffice, Google's productivity suite for creating and editing Microsoft Office word-processing documents, spreadsheets and presentations. An update to Quickoffice released in December improved performance and streamlined integration with Google Drive.
