On Android devices you can store your library of ebooks in Google Play Books.
This is a cloud based library which is accessible across all your android devices as well as in web browsers.
Adding your book to Google Play from Book Creator is simple.
1. From the My Books Screen touch the action menu for the book you want to upload
2. Choose ‘To Play Books’ from the menu
3. This will open the Play Books app on your device and start the upload of the ebook to your library
Upload and processing of the ebook can take some time, especially for large books with a lot of imagery.
When the processing has finished you will be able to read your book in the Play Books app on any of your devices, you can also read your book in a web browser at this address: https://play.google.com/books
Please note that at this time Google Play Books does not support the interactive functionality to trigger audio and video embedded in ebooks. You can choose to upload your book without these features.
