Android webview with webGL

Question

i am trying to find it a way from last few hours and couldn't done.

Issue: I have one html page and a webGL file(three.js file). I need to open this html file in Android Webview. WebView is failed to load the html page.

Below is the code that i have tried

        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");

I had placed all my resources inside sdcard.

Error log:
