Hi, I was wondering. iOS ans Android development is a pain in the ass, and requires (for the most part) some sort of native framework and language to make them work on those platforms.
I was wondering. How is development for Linux phones? I am guessing you would have to develop to the specific OS branch, like /e/os or PostmarketOS, to make it work on each devices, or is there a common language that just makes it executable for all linux platforms, so I only have to develop and deploy once, and then I will be able to put it on Ubuntus marketplace, etc? Anyone in here got any experience with this?


Depends on what you are trying to make, web app that is tested primarily on firefox is probably the easiest.
If it compiles on Linux desktop it can compile on a phone too, although only tried that a couple times with CLI stuff so far.
I think this should be the biggest selling point of both devs out there, but also users, since it’s crossover from desktop to your phone is so Smooth. Would be epic if you could have a linux os, that cross syncs to both you phone, tablet and phone via local wifi or something.
Syncthing does synchronize the Documents directory between my phone (LineageOS), laptop (Windows) and netbook (Debian) over the phone’s Wi-Fi access point. IIRC this is discouraged by Android security model so might only work temporarily. However, for me it’s very useful.
My Linux PC does sync data to my phone already. Linux and Android. Though file permissions are better on Linux, easier to setup properly.
What do you use for this?
Rsync
And you can costomize which folders etc. You wanna sync, browser data etc?
If I want to browse files on another device I use SSH. Rsync will sync what ever I tell it to.
