Native graphical Emacs on Android

As part of Emacs 30 Emacs will run natively on Android. I had already used Emacs in terminal on Termux but a native graphical app seemed better and I decided to try it. It took me a bit of time to understand the explanations and get it to work. The following are my notes on how I did it. Maybe it&rsquo;s useful for someone else as well.
