If you’re looking to lend a book on Android, there are a few things you need to know. First, the app doesn’t support physical books, so you’ll need to find an electronic version. Second, the app is limited in what it can do - it can only loan books for a certain period of time and it’s not possible to add or remove books from the list. Finally, if you want to keep track of how many books you’ve borrowed, you’ll need to use the library’s online borrower management system.
