I installed the f-droid app successfully to FireStick! (ADB and Debugging on)
Then adb connect to local IP of Firestick and then adb install *.apk All great and
adb tells me it was an success. Firestick even sees it as alternative marketplace app, all as it should.
But opening the APP I can navigate the menu but it does not refresh nor show the apps of f-droid.
Update: My FireStick was improperly once shut down and this caused it to forget
the access storage permission for the app. Now, it works! But I have to look for a mouse toggle app, since the search button cannot be reached by cursor alone…
