The Kindle Fire range of devices is Amazon’s answer to demands for a more functional device than the basic Kindle. All the more recent versions run an amended variant of the Android operating system, tailored to be Kindle-like, but also capable of running a wide range of applications. However, these applications are generally only available from the Amazon app store, not from Google Play or other Android app stores. Furthermore, Amazon’s terms and conditions for apps hosted on their App Store include requirements to pay them a substantial royalty if an app from the store is used to “sell” an item, such as a publication or training course materials. So what is the solution for PDF publishers? Well, Javelin for Android will run on Kindle Fire devices – see below for more details.
Javelin for Kindle
The Javelin secure PDF reader for Android is compatible with Kindle Fire (KF) and is easy to install and run… The screen resolution on the KF 7inch model is 800×1280, so not bad (much cheaper but not nearly as good as the new iPADs), and its dual 1.5Ghz processor is fast enough for even the most demanding of PDFs. We tested it on a couple of the largest documents distributed by our customers. These books have around 1000-2000+ pages and a large number of images and links. They load in a couple of seconds from completion of downloading, and because the entire document is held in virtual memory, they are almost instant when accessing any page.
Installing and running the Javelin app
Installation of Javelin on the Kindle is quick and simple – full details are provided here. To run the app you simply touch the Javelin icon and the Home page opens. For many users the documents they wish to view will be included within a catalog, either the built-in Catalog or a separate downloadable catalog of books, training materials or other documents. The publisher creates these and explains to end users how to download them. Touching the cover of a title in a catalog then downloads that book or document.For standard PDFs the file may then be opened immediately, whilst for secure PDFs (drmz files) an authorization code is usually required, after which the file may be opened and read.
If the Kindle Fire is your preferred reading device for ePUB books, newspapers and other materials, it can also be used for standard and secured PDF reading. As most Kindle Fire devices are quite small and not very high resolution it is best used for PDFs where the font is larger, the page sizes are smaller than standard, and/or the materials are graphical. It is also good for holding reference documents, where the user wishes to select an item and can zoom in to check details, rather than reading lengthy blocks of text.
