First and foremost, Google Drive for Android is not a new app. It’s the good old Google Docs app, rebranded. In fact if you have Docs installed and search for Drive in Play Store, you will see it installed and available as an update. In the app itself, not much has changed. It’s the same interface that we are all familiar with, with a few Drive-specific features added.
The Android client differs significantly from the Windows and Mac clients in that it does not give you a folder that’s kept in sync with the cloud. You just get a phone and tablet optimized interface to browse through the files stored on your drive, edit your Google Docs files directly, download them to your device or selectively make individual files stay in sync with the ‘Make available offline’ option.
