Android studio is doing like 80% of the work for me, and I'm still not done with this tiny app. :/

@sudocode Thanks <6 for that useful suggestion. I'll immediately transfer some spare RAM from my phone via bluetooth as a localhost ISP.

This zero-day cutting-edge Bluetooth 5.0 technology supports transferring physical stuff when paired with NFC over OTG. This is unlike any other techniques I've discovered so far. Sadly this is an android-only feature due to hardware limitations on Apple's side. Needless to say, "allegedly" they are working on it.

Tell me about it. All Android projects appear small at the beginning but the dev soon realizes how complicated it can get.

@null-pointer-ex Exactly! I thought it would take 4 hours at max. But the whole weekend is gone :D

Android does a lot against you not for you. Just turn your App and destroy your dreams of stability.
