That is not possible because the directory
is only created / used for degugging and is not available for the compiled app (APK). Files that are saved here (with the File component by saving a text file without a slash) are saved with the APK in the internal storage:
This directory is only accessible with a rooted device.
You should therefore save the csv file in a folder of the external storage, for example:
/storage/emulated/0/Documents/ or /storage/emulated/0/Download/
If you enter new, more words, the length of the list should actually increase, right?
And how does the user know which word from the list to work with afterwards? How does the user know which word was added?
Questions & questions ... so to shorten this, create a small test aia with only 3-5 words and post the blocks (aia). Put the csv file in the assets (Media).
