I'm trying to create a gallery with images, which are somewhere on the internet. The exact source can be found in a txt or html file(whatever type is needed). Now I'm trying to get Android to read the txt file, and put the links (could be 0, 1 or 100) into a gallery (as images of course). My problem is now that I don't know how to tell the app that it should read the txt file and then decide how many pictures it could produce in the gallery.
Button A -> "click" -> (check A.txt, read links) -> (5 links found) -> show 5 pictures in the gallery.
In A.txt there could be a dozen pictures of just one, so I can't create a gallery in advance.
How can I implement this feature?
Any help would be appreciated!
