if here are all your codes, then
you are copying file from shared to shared?
you did not remember last time the index number, so next time you open you app, it's counting from 1 again, that will overwrite your prevoius images.
and have you tested your app on other devices with newer Android versions?
Yes, sorry, I need to fix the copyfile part and I've noticed the rewiting over images thing, but what I mean by "works" is that it successfully saves to the folder stated ^^; sorry for confusion
yes in your own devices with Android 8.
I don't really have any other devices to test this on; this is a school project and so it doesn't really need to run on devices other than my own. I didn't realize my android version was really old (LOL), I'll update it
What my issue is is that I want to only display images taken from the camera within the app. It doesn't really matter to me whether they are saved to Shared or ASD.
It looks like I got something to work, by making it into a compiled app 
I got everything to work!
This code takes images with camera, shows them on screen, and saves them to the app folder with the index number as the file name (does not rewrite over images!)
Thank you so much for your help everyone 
It was hard but I figured it out thanks to all of your help
Waaah, one more problem: I implemented the code into my app (I'm creating an app and this whole thing was just one of the screens) but now it gives me an error when trying to pull images. Can anyone tell me why it's doing this and how I can fix this? It seems like it can find the html code when initializing, but when I try to pull the images it freaks out.
