  Fixed link. It wasn't GitHhub but GitHub.
  And it's not anything 'bout font but posting proper formatted code in this forum! :(|)

  File data/tabledemo.csv contains a path separator

  This looks to be the problem. Get rid of the data/ from the start of the filename.

  Thank you GoToLoop and koogs

  CTRL+o used to format code the following works as an example of code that

  a) look for a table to initialize a variable xint;

  b) if the table does not exist, for example after a first install, create the table and initialize x with a desired first run value

  c) after each draw(), updates x in the table;

  d) should the android activity lose focus, when onResume is called, and draw() resumes, the prior value of x is restored.

  I hope this is helpful to others and thank GoToLoop and koogs for the advice. I can't say where in the Processing development environment to put a handcrafted initialization file, the above example avoids this by creating the table and letting the system calls decide where to put this.

  I hope this is helpful to others and thank GoToLoop and koogs for the advice.

  Final question: do I post a bug report so the processing reference can be updated?
