How to Sideload Apps Onto Your Amazon Fire TV Stick. Thinking of getting an Amazon FireStick, now that it is voice controlled? Well, it will require some work if you want to get all of your Android apps on it. First, you have to download and install a free app, AppstoFire, from the PlayStore. Then, you have to set up ADB debugging on the Stick. Then, you can sideload your apps to the FireStick, and have an alternative to Roku. I am going to plug a FireStick into SWMBO's Roku TV so she can have voice control of the FireStick. Sounds like a fun Saturday afternoon.
