Fix for Amazon FireOS devices

[emtee40]

It's slow when cleaning cache, but it works.

Accessibility Service
First get this app mentioned here. It runs very annoyingly and very similar to Shizuku (ie: having to reopen app to start service for requesting app..). This will grant Accessibility Service.

For the next steps Remote ADB Shell is needed. Find it here.

Grant Usage Permission
Open Remote ADB and connect.
Run this command:
pm grant eu.darken.sdmse android.permission.PACKAGE_USAGE_STATS

Grant Drawing over other apps
Open Remote ADB and connect.
Run this command:
pm grant eu.darken.sdmse android.permission.SYSTEM_ALERT_WINDOW

Extra suggestion
Use Remote ADB again and run this:
settings put global hidden_api_policy 1

Since FireOS is based off Android 9 maybe, I ran both commands:
settings put global hidden_api_policy_p_apps 1

Conclusion
It works. Change out package name for OG SD Maid and it will run as well. Both verified. Just remember that first line of this message: Very, VERY, slow when cleaning app Caches.

What makes it slow? Does SD Maid need multiple retries? Or does the FireOS UI react slow?

Can you make a video that demos it?
