psychoanima winkr7 I tried it on my Android 10", but I find it a bit hard to change anything without a mouse. I do have a keyboard for my tablet. You could buy one of those tablet cases that come with a keyboard, which connect to the tablet with Bluetooth for example.
I did buy a small USB-C mouse (fits in the charger port of the tablet) and a small mousemat for it but haven't tested with that setup yet. I really only program on PC. Much larger screen, bigger and faster everything!
But in the sense of portability, a tablet case with keyboard and a mouse, or even a wireless pen mouse (a pen mouse can make use of almost any small surface) could do the trick for you.
I did notice you can't really do much in the layout editor though, the side bars are missing or are they accessed elsewhere? It's kinda crucial to be able to check instance variables and object properties when programming.
