I have nearly finished my first android app using Processing 3 for android. This app uses the command saveStrings(string,filename) to store textfiles with extension .txt wchich works fine. In processing the files appear inside the sketchfolder (not the data folder). In android I do not know where they are.
Now the question is, how to show a list of all files with extension .txt , so that one can load the one we need to work on inside the app. My idea would be to create a rectangle inside which this list should appear. Does anybody know how to manage this?
Thanks a lot for your help, this is would be just the last unsolved piece for my app.
