Reading pdf books on my phone When I want to get/download books from Google Play Store, I usually get this notification:



But then I am not sure what to do afterwards to be able to read those pdf books on my phone. I've installed to ebook reader apps (kindle and another one), I also downloaded Google Play books app but I can't find those books exploring in those ebook reader apps and I can't find Google Play Books app on my phone to check whether it is possible to read them there.
You can download the Google Play Books app from the market (link)

If there is a problem with your installed app, open the app using Play Store app and uninstall and reinstall it. Now you should have the app shortcut in your app drawer. 

In this app, you will be able to view your purchased books.
