How do I buy my ebooks from Charis?

As Kindle Fires are popping up around the US, many of you have been asking whether it
is possible to buy Google eBooks on the
Kindle Fire. After all, the Kindle Fire is based on Google's Android
operating system, and IndieCommerce has worked with Bluefire to create
the IndieBound Reader app for Android devices.

The answer is that it is in fact possible to run the IndieBound Reader app on the Kindle Fire through a process called sideloading. Sideloading refers to the practice of installing apps without going through the official app store on a device.

There are many great sideloading walkthroughs for the Kindle Fire online. Below is a particularly thorough one from Liliputing:

And a YouTube video:

And finally, some threads on Amazon's own forums on the topic:

An APK file (described in the tutorials above) for IndieBound Reader can be downloaded directly from http://www.indiebound.org/reader.

Please note: IndieBound Reader was not specifically developed to
run on the Kindle Fire. However, the app has been tested with good
results on this device.

Also, customers should consult
Amazon's Terms of Service before attempting to sideload apps. As of
12/22/2011, there was nothing in these Terms of Service precluding this
practice, but users should check in case Amazon's terms have changed.
