About this APK

FBReader: Favorite Book Reader is an app by FBReader.ORG Limited in the Books & Reference category, listed since June 2011. It includes native code only for x86 32-bit, so it won't install on ordinary ARM phones (only on x86 devices such as emulators and some Chromebooks).

Since version 2.8.13, the APK grew from 6.6 MB to 7.5 MB. Since version 2.6.14, the minimum Android version rose from 2.0 to 4.4. It asks for 9 permissions, 3 of them sensitive: access all files, read shared storage and modify shared storage. Compared with version 2.8.13, it adds 2 new permissions (“Access all files” and “Show notifications”) and drops 1 (“Prevent the device from sleeping”). The app offers in-app purchases through Google Play.

When the device is online, you can access many ebook catalogues, where books are available for free and for a fee. Several popular English, French, Russian, and Polish libraries are included. Custom OPDS catalogues are supported too. Alternatively, you can download books manually and save them on your device. FBReader can synchronize your library, bookmarks, and reading positions via the Book Network, a Google Drive™ based cloud service. The synchronization is disabled by default; to enable and configure it, use the preferences dialogue. The app is integrated with external dictionaries, including Dictan, ColorDict, Fora Dictionary, FreeDictionary.org, and LEO dictionary. The Premium edition includes built-in integration with Google Translate. FBReader is fast and highly customizable. You can use external TrueType/OpenType fonts and custom backgrounds, the screen brightness can be adjusted while reading (slide finger up/down along the left screen edge), and different day/night colour schemes can be selected.
