View Google Books in Android mobiles? Is it possible to see Sample Preview or Full Google Books, in Android devices? 

Do we have an app for that?

I have Android 4.2 in my Micromax Ninja A89.

Small parts of all books are viewable in Google Books, they call it "(Sample) Preview", I want to be able to see this preview in Android, even if I am not able to download, I want to view it with an active internet connection in my mobile.
There is a Google-made app with almost exactly that name, that does let you read Google Books on your Android device, Google Play Books. I'm pretty sure that should do what you want.
