ES file explorer being one of the best file manager for Android now provides support for Goole drive and drop box integration. I personally feel this as a cool feature which allows you me to send emails with my saved documents so easily
The following screen shots will tell you how to use this feature
1. Open es file explorer and change the view from local to net
2. Next select Google drive or drop box from the selection menu and provide username and password to authenticate
3. That's it your Google drive is ready to use with your favourite file explorer
