I don't think your IDE really matters all that much, so long as it's got the core stuff. It's really more of a personal choice. You might personally find you care more or less about certain features, but I don't think mobile dev demands anything that would pull you away from your preferred choice. I haven't done any mobile Dev, so I could be wrong, but I've done a little research into it and haven't found anything to suggest I'm wrong.

I personally like NeoVim with a handful of plugins to flesh it out. I don't remember my exact load out at the moment, but I'd only recommend it if you like Vim or are interested in learning to use it. It's the best text editor I've ever used, so once you add some plugins for some of those IDE features, it's pretty great.
