Jfc xmrig for Android is easy af to get running just USE TERMUX, build, and you'll have a pocket hand warmer in no time.
Discussion
I have no idea what "use termux, build" means, plus I hate termux
Well then it ain't for you.
Then XMRig for Android isn't actually that easy to use and that should be an urgent priority to fix for Monero community devs
Easy af here it is running ony pixel and this took less than ten minutes to build from source.

So give me a step by step guide and I'll probably try it sometime soon, after I'm done confirming whether I can use gupax
Make sure your method will work in a secondary profile on an older Pixel because otherwise I'll be limited to devices I don't mind using the main profile on
This is a pretty old pixel, but same build method works on my old chinesium test phone and quite sure i could even build it for my ancient samsung I posted a few days back.
If you want hand holding to build, etc I'm a mercenary - that'll cost ya because my time is valuable. Otherwise sufficient info is freely available with a web search.
I'm not offering to help beggars, I'm offering to test Monero mining software during an attempted 51% attack
What is it with you fucking people posting nostr replies that are just YouTube links 
And don't forget to make sure your method works as simply as possible for all users because the goal is to promote widespread mining, not just have me try to slap down a 51% attack as a one man army with my own devices
If there are ARM builds, another option could be to run it on a native #Linux phones like #Flx1.
#postmarketOS can run on some Android phones like Pixel 3a, OnePlus 6, Fairphone 5, etc and may be able to do this also.
