Android webview与webGL

Question

我试图找到它从过去几个小时的方式，无法完成。

期：我有一个html页面和一个webGL文件（three.js文件）。我需要在Android Webview中打开这个html文件。 WebView无法加载html页面。

下面是我放在SD卡里面我所有的资源，我已经尝试

 WebSettings settings = webView.getSettings(); 
    webView.addJavascriptInterface(this, "Android"); 
    settings.setJavaScriptEnabled(true); 
    settings.setDomStorageEnabled(true); 
    settings.setJavaScriptCanOpenWindowsAutomatically(true); 
    settings.setUseWideViewPort(true); 
    webView.setWebChromeClient(new WebChromeClient(){ 
    }); 
webView.loadUrl("file://" + Environment.getExternalStorageDirectory() + "/Android/index.html"); 

的代码。

错误日志：

任何一个可以建议我什么，我有什么关系？

尝试启用以下设置：

settings.setAllowFileAccessFromFileURLs(true); 
settings.setAllowUniversalAccessFromFileURLs(true);
