WOW…
I removed the config file (“config.txt”) that I had for my original settings from the data folder.
Apparently, when the app starts it replaces whatever file I modified and stored with that same name, with the original config.txt file that I had in the data folder when the app was exported.
Now when the app is installed and executed for first time it can’t find the file, but catching the exception allows me to write original settings from my code, and save the file. For the next executions of the app it just opens the last saved config.txt like it is supposed.
It is a learning curve, for sure!! =)
