Unity StreamingAssets Android 讀取檔案的坑

Unity StreamingAssets 在 Android下的坑有兩個

1. 如果要用 AssetBundle.LoadFromFile 的 API Assetbundle 讀取路徑要改成

      
     string p = Application.dataPath + "!assets";
     AssetBundle.LoadFromFile(path + "/" + MyAssetBundle);

2. 如果是讀檔案不能直接使用 File.xxx 系列 要改成用 WWW or UnityWebRequest 

      
     var unityWebRequest = UnityWebRequest.Get(Path.Combine(Application.streamingAssetsPath, "MyFile.txt"));
     unityWebRequest.SendWebRequest();
     while (!unityWebRequest.isDone) { }
     string txt = unityWebRequest.downloadHandler.text;
