Good Day All, I have virtually completed my little Unit Price app, and am refining saving of data. But things have suddenly changed markedly. Up to recent I used the '/filename' system which worked well on all my devices. Then, after googles security update system this no longer works as cannot access SD card. There is no need for me to have any specific directory or folder, and, to configure only for sd card. When I changed to saving simply 'filename' it works without question on all my devices, with the data back on phone not SD card. It runs on all my devices from my old Samsung S4 running Android 5 to new Samsung 20 Ultra 5g, running Android 11. I am quite happy with this configuration, if I build a package 'Bundle' 'aab', will this continue to run on all without problems? Thanks in advance.
This works well
