As already noted, I’ve just received my new Kindle Fire 7. And one of the first things I wanted to do with it was install my library of DRM-free EPUB books. Ideally, on the Kindle Fire’s microSD card. After all, that’s what external memory is about, right?
Following David Rothman’s tips, I installed Mantano Reader Lite from an .apk file, which I pulled off a backup on my Lenovo A7-10, since it’s not available on Amazon’s Appstore. ES FileExplorer gives you an easy way of getting these by going to its homepage, then the User Apps screen, and long-pressing on the app of choice till the Backup option comes up on the menu bar below. The .apks are stored in a Backups folder in your Android device’s memory. Once I’d swapped the .apk over to my new Kindle Fire’s microSD card, all I needed to do was allow Apps from Unknown Sources under Security in the Kindle Fire’s Settings, then click on the .apk, and it installed smoothly.
I chose Mantano Reader Lite because I’d already found from my Lenovo A7-10 that it could access an external memory card even when the system’s memory configuration locked most apps on to a virtual SD card in the main memory. And when I hit its Import icon to find compatible books, the app navigated automatically to the Books file I’d created on the microSD card, and offered to import all the EPUB files. Moments later, I had a full library of EPUB books from the microSD card on my Kindle Fire 7.
This may work with a number of other EPUB ereader apps, though I’ve found that Mantano is one of the few that’s so capable at navigating file systems. In any case, the new Kindle Fire’s microSD card can hold all the EPUB files you want – so long as you’re ready to go through the cumbersome .apk copy-and-install procedure for the app.
