Hi there and welcome
Android is a customized operating system for each device, so there are different releases as it needs to work with the hardware. Providers of the hardware do this.
Amazon have their own version, you cannot install for example, Android designed for a samsung phone to the Tablet, so you are stuck with the version you have.
But what you can do is side load apps for Google
To so this, first go to Settings, applications and make sure Apps from unknown sources is turned on
Then download this file onto it
Then install the App ES File Explorer on the Kindle to be able to open the file you just downloaded
Use the Fire tablet’s Docs app to locate the downloaded apk app files to install them. Generally the default location is Docs > Local Storage > Download if you used the web browser to download the files above.
The Google apps must to be installed in the following order to work:
Google Services Framework
Google Play Services
Google Account Manager
Google Play Store
Once that’s finished you can open the Play Store and sign in to your Google account.
Step #4: Update and Restart
After you open the Play Store for the first time you need to install the YouTube app and then open it. This will prompt the Play Store services to update to the latest version, an important last step. Once the update is installed (it takes awhile), power off and restart your Fire tablet.
Now the Google Play Store app should be good to go
If you have any problems, or would like any additional information or assistance, please do not hesitate to let me know.
