If you own an Amazon Kindle Fire tablet, you’ve quickly learned that you only have access to the Amazon App Store for downloading and installing Android apps. The Android Market (which is used by all other Android phones and tablets) is not available for the Kindle Fire. Since most of the available apps are in the Android Market and not in the Amazon App Store, this is a real drag.
Some KF owners have rooted their tablets to gain access to the Android Market, but as you may have read in one of my previous postings I decide to not go down that route for a number of reasons (include voiding the warranty of your tablet). Instead, I’ve taken the “side loading” approach which allows me to install desired apps outside of the Amazon App Store.
If you do a Google search on “kindle fire side loading” you’ll come across many web sites and blogs that explain the process. Basically, you need to install a desired app on another Android device (like a different tablet or cell phone), then use a File Explorer app to make a “backup” of that app. Next, you copy the backup file of that app (which is a standard .apk Android installer file) over to your Kindle Fire and install it. It’s a multi-step process, but you don’t need root access to do this procedure.
In my case, I have an Acer Iconia 10″ Android Tablet that I use to install my desired apps. I then use the app called Astro which is a file explorer app on my Acer tablet to do a “backup” of selected installed apps to the internal SD Card. For convenience, I’ll then use the DropBox app on my Acer tablet to upload these apk files to my DropBox cloud account. Finally, I run the same DropBox app on my Kindle Fire to access my online account, and just tap on the apk files. They then automatically download and install themselves. Using Dropbox in the manner is convenient for me, but you can always transfer the apk files from your PC or Mac over to your Kindle Fire via a USB sync cable.
Note, that not all 3rd party apps will install on the Kindle Fire, as some required Google libraries are not present. For example, the Pageonce Travel app that runs fine on my Nexus S phone and Acer Tablet won’t install on my KF (I think it’s because certain Google Location Libraries are not present on the KF). So be aware that not all apps can be loaded using this side-loading method.
