Okay so I made program completed but then turns out name I had used needs to be changed. I couldn't figure better way so I simply created new project and created all the files in there and copy pasted everything bar the package part so that it would use new package name. Program seems to compile. Yey! However when I try to install it to phone it doesn't appear there... What did I do wrong and is there better way to switch projects properties so there's no hint of original name at all?
