Hi. I am saving my all App images in SD-Card where the default folder is created by app with app id name (com.xyz.appname)
but after restarting device those images automatically appeared in device gallery. and I want to prevent those behaviour. some ware I found that we can prevent them by adding prefix .(dot) in file name. so gallery will not trace those file which have prefix .(dot).
I tried to do that but i am not able to write the file with prefix . (dot)
