streamingAssetPath Android

Description

Contains the path to the StreamingAssets folder (Read Only).

If you have a "StreamingAssets" folder in the Assets folder of your project, it will be copied to your player builds and be present in the path given by Application.streamingAssetsPath.

Note that on some platforms it is not possible to directly access the StreamingAssets folder because there is no file system access in the web platforms, and because it is compressed into the .apk file on Android. On those platforms, a url will be returned, which can be used using the UnityWebRequest class.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    public string filePath = System.IO.Path.Combine(Application.streamingAssetsPath, "MyFile");
    public string result = "";
    IEnumerator Example() {
        if (filePath.Contains("://")) {
            Networking.UnityWebRequest www = Networking.UnityWebRequest.Get(filePath);
            yield return www.SendWebRequest();
            result = www.downloadHandler.text;
        } else
            result = System.IO.File.ReadAllText(filePath);
    }
}

 

 UnityWebRequest uwr = new UnityWebRequest(streamingAssetsUrl);
                    uwr.downloadHandler = new DownloadHandlerBuffer();
                    yield return uwr.Send();
                    if (uwr.isNetworkError || uwr.isHttpError)
                    {
                        Debug.Log(uwr.error);
                    }
                    else
                    {
                        File.WriteAllBytes(persistentDataUrl, uwr.downloadHandler.data);
                    }
