simipoB/Galar-Native-Android ? reverse-engineered prompt

Build me an Android app that lets me run Pokémon Sword and Shield natively on my phone, using my own legally dumped game files and keys.

I want it to be a single app that can set up either game, keep them separate with their own saves, settings, and mods, and then launch straight into the game after setup. It should work with touch controls and also with external controllers, with an easy way to bring up the menu, remap buttons, and support rumble if possible. Add a settings screen for graphics, upscaling, frame rate, control layout, language, performance info, and importing or exporting saves and mods.

It should also support local play for trades, battles, and raids with nearby devices or through an online room, and save useful logs so users can share them when things go wrong. If you need to look up current Android or Vulkan docs online, go ahead.
