How to reference a filepath for streamreader on android device?

I am making a word game and trying to use a few .txt filex as csv dictionaries to reference. I am using a streamreader because I have CSVs and I am trying to read the file Line by Line.

A streamreader however, requires a datapath string to operate. In the editor this is fine. I can use a number of options to reference the file by path. However, none of them work when I build to an android device because the filepath becomes irrelevant and doesn't exist in that world.

I have tried: path = Path.Combine(Application.dataPath, filename); path = Path.Combine(Application.streamingAssetsPath, filename);

Resources.Load doesn't work because (as far as I know) I can't reference it as a datapath and if I load a TextAsset I can only convert that to a single string rather than read it line-by-line. So....how do I load these .txt files into my project and read them with a filestream? is there a path I can save them to? or is there an alternative to StreamReader that doesn't require a path?

PLEASE HELP
