. . .
To make matters clear we are talking about the cheap Fire tablet. I think they sell for $49.00 USD. I never use it so I really have no idea what it can do. I know that it uses the same programing language as whatever is used in the Google Play Store. Even though we are blocked from the Google Play Store there is some sort of hack we can use to get to it, but I don't want to do that because from what I have heard if you click the wrong link on the redirect page you get malware, so I am sticking with whatever is in the Amazon Fire Store.
Firstly, does anyone know if the Fire has the butt to run the videos and audio, and secondly what, if any, third party apps did you need to download from the Amazon store to get it to work?
The problem is a little deeper than you describe. (I know you're working on a solution -- this information is for general background.)
Years ago, Amazon decided that it didn't want to give Google control of the Android operating system (that's the core software on all Android devices) that ran on Amazon's Fire tablets.
So Amazon "forked" the Android O/S, around version 4. Google continued to develop Android (it's now at version 10 or 11, I think), adding new features. But Amazon's Android was under Amazon's control, not Google's. They've continued to work on it (it's now Fire version 7).
In the past few years, Google has added some libraries to "Google Android" that are _required_ for a program to be in the Google PlayStore.
You can get a Fire tablet to access the Google PlayStore (using "F-Droid" and "Yalp" software), and download programs from it. But -- in my experience -- those programs probably won't run on the Fire, because the first thing they do is check for the existence of the new Google libraries, and terminate if they don't find them.
. . . Welcome to the Wild West !
I have a Fire tablet which I use a lot. It's fantastic value per $, but I've given up trying to use Google PlayStore software.
If you find a general-purpose way to beat this problem, please let us know. Meanwhile, good luck! --
