Prerequisites (needs root):

  IMPORTANT:
  Scripts and instruction in directory 'android' are OUTDATED and
  not maintained any more. Instead refer to directory 'buildozer'.

  You need a linux workstation (either native or virtual). No graphic
  desktop is needed, cmdline only is sufficient.

  On freshly installed systems you will need to add about the
  following packages:

  On a 'freshly installed' Ubuntu or Debain , the following
  additional packages had to be installed:

  - python-setuptools
  - javasdk          (ubuntu: default jdk)
  - cython           (ubuntu: cython)
  - pip              (ubuntu: python-pip)
  - pexpect          (ubuntu: python-pexpect)
  - zlib headers     (ubuntu: zlib1g-dev)
  - virtualenv       (python-virtualenv)
  - zip,unzip

  On a 'simple' gentoo installation the following packages had to be
  installed in addition:

  - dev-python/pip
  - dev-python/virtualenv
  - dev-python/cython
  - dev-media-libs/libsdl2
  - dev-media-libs/sdl2-image
  - dev-media-libs/sdl2-mixer
  - dev-media-libs/sdl2-ttf
  - dev-media-libs/gstreamer
  - dev-vcs/git
  - dev-java/ant

  For further instructions consult buildozer/build-instruction.txt.

  NOTES:
  1) This information is supplied to give you a hint, when running into
     problems.
  2) All builds need an working (fairly fast) internet connection and
     6 GB of free disk space.

Cardsets:

  The Apk includes a minimal set of cards for playing.

  On Android 9 and lower you can also add additional cardsets:

  Additional cardsets can be installed in ${HOME}/.PySolFC/cardsets/.
  On an android device this is equivalent to /sdcard/.PySolFC/cardsets/.
  Cardsets must use the 'png' image format. Use scripts/cardconv
  (on a linux system) to convert them, before copying them to the device.

  IMPORTANT: This can only be supported for Android Version 9 and lower.
  Android as of Version 10 and later restricts access to so called
  'external-storage' drasitcally. There is currently no way around it
  with the given application.
