symfonium has been mentioned in this post before specifically for android auto. i had the same hang up with apple car play. i didn’t use most of the plexamp fancy features. i just wanted it to play music and be easy to use when driving. manet finally came along for ios. though i’m still hoping one of the open source apps adds the functionality later.
if you want easy java minecraft i might try something like https://github.com/itzg/docker-minecraft-server though i’ve not tested that one beyond ‘it did install’.
for bedrock this walkthough does a good job of covering the steps. https://harrk.dev/dedicated-bedrock-minecraft-server-ubuntu-setup/
microsoft has a habit of changing the download url regularly so automating it gets annoying. my kid has moved onto java so i’ve just left the bedrock server shutdown.
if you really want to run a java server outside docker and you’re comfortable with bash scripts, i can post mine here. but one of the docker builds is going to be the simplest way to get started with it.
