I use this app called bookshelf by Damir Juretic https://play.google.com/store/apps/details?id=com.bookshelf.prod&pcampaignid=web_share
you can scan the barcodes, or even the ISBN text printed on inner cover.
can have multiple virtual bookshelf's to represent your physical shelfs if you like, has a search feature too.
can export and import csv files of the inventory too
no ads and free, I haven't had any issues with it.
