Remarks

Use the 
StreamingAssets
folder to store assets. Create it in your project at Assets/StreamingAssets. At runtime, 
Application.streamingAssetsPath
provides the path to the folder. In a built Player, the StreamingAssets location can differ from the project folder, so always use 
Application.streamingAssetsPath
. Add the asset name to 
Application.streamingAssetsPath
. The built application can load the asset at this address. You can use the Debug.Log class to print the path to the 
StreamingAssets
folder to the Unity Console.
You cannot use synchronous filesystem APIs, such as the C# 
System.IO.File
class, to access the 
StreamingAssets
folder on the WebGL and Android platforms. No file access is available on WebGL. Android uses a compressed 
.apk
file. These platforms return a URL. Use the UnityWebRequest class to access the assets.
using UnityEngine;using System.IO;using UnityEngine.Video;// Application-streamingAssetsPath example.//// Play a video and let the user stop/start it.// The video location is StreamingAssets. The video is// played on the camera background.public class Example : MonoBehaviour{    private UnityEngine.Video.VideoPlayer videoPlayer;    private string status;    void Start()    {        GameObject cam = GameObject.Find("Main Camera");        videoPlayer = cam.AddComponent<UnityEngine.Video.VideoPlayer>();        // Obtain the location of the video clip.        videoPlayer.url = Path.Combine(Application.streamingAssetsPath, "SampleVideo_1280x720_5mb.mp4");        // Restart from beginning when done.        videoPlayer.isLooping = true;        // Do not show the video until the user needs it.        videoPlayer.Pause();        status = "Press to play";    }    void OnGUI()    {        GUIStyle buttonWidth = new GUIStyle(GUI.skin.GetStyle("button"));        buttonWidth.fontSize = 18 * (Screen.width / 800);        if (GUI.Button(new Rect(Screen.width / 16, Screen.height / 16, Screen.width / 3, Screen.height / 8), status, buttonWidth))        {            if (videoPlayer.isPlaying)            {                videoPlayer.Pause();                status = "Press to play";            }            else            {                videoPlayer.Play();                status = "Press to pause";            }        }    }}
The following code example demonstrates how to access a file in the 
StreamingAssets
folder on Android (and similarly WebGL) platforms. On both Android and WebGL, treat 
Application.streamingAssetsPath
as a URL and use UnityWebRequest (not synchronous filesystem APIs such as 
System.IO.File
) to read StreamingAssets.
using UnityEngine;using UnityEngine.Networking;using System.Threading.Tasks;public class LoadStreamingAsset : MonoBehaviour{    async void Start()    {        string filePath = System.IO.Path.Combine(Application.streamingAssetsPath, "filetoload.txt");        UnityWebRequest request = UnityWebRequest.Get(filePath);        UnityWebRequestAsyncOperation operation = request.SendWebRequest();        while (!operation.isDone)        {            await Task.Yield();        }        if (request.result == UnityWebRequest.Result.Success)        {            Debug.Log(request.downloadHandler.text);        }        else        {            Debug.LogError("Cannot load file at " + filePath);        }    }}
