v0.2.3 — Android (experimental)

Downloads: the same three setup programs; use these instead of the earlier
ones. There is no APK to download: the Android version contains the game's code,
so it is built from your own ROM on your PC, like the PC version.

New

• Build for Android in the setup program (--android without a window).
  It downloads Google's Android NDK and SDL2 (once, checked against their
  published checksums), compiles the game for 64-bit ARM Android 7.0+, and makes
  a signed APK to copy to the phone or handheld and install. No Java or Android
  Studio is needed: the APK is packed and signed by tools/android/apk.py.
• On Android: full screen in landscape; on-screen buttons (D-pad, A/B/X/Y,
  L/R, Start, Select, Menu), hidden while a controller is being used and back at
  a touch; fingers on the picture touch the game's touch screen, several at
  once; Back opens the pause menu; the save is written when the app goes to the
  background; messages and frame timings go to log.txt in the app's storage.
• Tested in Google's Android emulator (Android 14): installs, updates over
  itself, loads a save, plays with the on-screen buttons and touch, pause menu.
  Not yet tried on a real phone or handheld: reports welcome, with
  log.txt if something is wrong.
