Official Google Mobile Blog: Updates to Google Docs app for Android: Offline access and improved tablet experience
There may be times when you don’t have an Internet connection on your Android device, but you still want access to a file you’ve saved in Google Docs. Now you can select any file in Google Docs to make it available offline. So regardless of whether you’re connected to the internet, you’re always connected to those files.
Even better, Google Docs automatically updates your offline files when you’re on Wi-Fi. You can also manually update files anytime you have a data connection by opening the file or tapping ‘Update’ from the Offline section of the app.

For those of you with Android tablets, we’ve also improved the Google Docs reading experience. Now, when you open a Google document on your tablet while online, you’ll get a high-resolution version of the document. Swipe left and right to flip between pages, or use the slider at the bottom to page ahead quickly.
