Question

I was able to get the sample above to work on my Android device just fine using local images!

 

I'm creating an Android camera app. using Xamarin, taking pictures and storing them in a unique folder (... files/Pictures/Sample/test1.jpg) on my phone. Each picture is simply numbered "test_n.jpg" as more are taken. My problem is I have an imageSlider at the bottom of the screen that I wish to load "all" the pictures from that picture folder on my phone. How do you specify a specific folder (external) from your phone as the source of the imageslider? I can display local images just fine in the slider by doing the imageSources.Add("picxxx.jpg"), but I can not get it to load from an external picture folder.
