I was searching for YouTube clients on my KDE Plasma Bigscreen GNU/Linux TV box, and found NewPipe, a popular Android YouTube frontend. Turns out this tool is how they moved it over.
Great solution alongside projects like Waydroid, as you can post individual apps to Flathub or other Linux storefronts, rather than needing to install a whole ROM to get your Android apps to appear in your Linux app tray.
It doesn’t work like Wine, but I suppose the goal one day is to be able to click .APK files to install like you can with .EXE files with Wine. Currently developers need to integrate it for their (or their favourite open source) apps to install on Linux.
How did you get Plasma Bigscreen? Last time I checked it said that it was “still in development” and the website didn’t provide any builds.
If you run something like Debian Bookworm, or based on it, you can apt install plasma-bigscreen to run the older version. New version you likely need to compile depending on your distro
