There are some really cheap and good options out there. A well-sized Huion pen tablet can be around $30 or so

I don’t think there are trackpad styluses. You can probably get a graphics tablet that’s about the size of a trackpad for $40. This one goes for $33, but I’d recommend the slightly larger ones for $50. Just search for “battery-free graphics tablet”.

I believe the 420 series have long been replaced by H430P now, which this one actually supports Android. The OTG adapter is sold separately though.
To directly answer your question, I don’t think it supports Android nor Huion will update it with it.
