Here you can find a tutorial about installing alternative keyboards to your Amazon Kindle Fire. If you don’t like the virtual keyboard that was pre-installed on your Kindle Fire, you would look around for some other keyboards that can be installed to the device. You can install the android 4.0 Keyboard from the market, it is very easy. Here I want to show you a method that allow you to install other keyboards such as Swype and swiftkey to Amazon Kindle Fire. The following steps should help you.
install Swype or swiftkey to Amazon Kindle Fire:
1. Install your preferred keyboards from Market
2. Use ES file explore (with Root feature and RW mount enabled in the advanced setting) or use Root Explorer to copy the keyboard .apk file from /data/app to /system/app
3. Reboot (shows several FC) and clicked that apk file to re-install it. Then you should delete apk file from /system/app, otherwise it goes to FC again once it’s rebooted.
4. Select the keyboard by pressing and holding at any text input box.
