How to work with files in StreamingAssets?

Question

Android

The Unity project is implemented for android. I put the files in the StreamingAssets folder in the Assets folder. I write the path to the file:

fileName = "jar:file://" + Application.dataPath + "!/assets/" + "questions.txt"

I'm trying to write a certain string to an object on the stage through a function:

public void ReadFile (string filename, int numberQuestion) {
        using (StreamReader reader = File.OpenText(filename))
        {
            string line = null;

            for (int i = 0; i <= numberQuestion; i++) {
                line = reader.ReadLine();  
                questionText.GetComponent<Text>().text = line;

            }
        }

    }

But doesn't work. Although, by specifying a relative path and running from the computer, it worked.
What's wrong?

Answer 1

And in general, text data can be accessed in resources as TextAssetwell as not having trouble with files.

Answer 2

On android, you need to work with streaming assets through UnityWebRequest. And it is not at all necessary to form the path in this way - dataPath will already seem to contain an appendix in the form of a jar
