AdvancedWebView loading html from phone storage issue

Hi i am using compile 'com.github.delight-im:Android-AdvancedWebView:v3.0.0' for display html5, my target file is stored in my phone storage path is "file:///storage/sdcard0/DcLms/Conjunction/index.html". when I am working with normal android WebView no issues. But trying with above mentioned library i got Webpage not available issue. 

 String targetPath = "file:///storage/sdcard0/DcLms/Conjunction/index.html";
 AdvancedWebView webView = (AdvancedWebView) findViewById(R.id.webView);
 webView.getSettings().setJavaScriptEnabled(true);
 webView.setWebChromeClient(new WebChromeClient());
 webView.getSettings().setDomStorageEnabled(true);
 webView.setWebViewClient(new HelloWebViewClient());
 webView.loadUrl(targetPath);

 WebView basicView = (WebView) findViewById(R.id.basicView);
 webView.setWebViewClient(new HelloWebViewClient());

 basicView.getSettings().setJavaScriptEnabled(true);
 basicView.setWebChromeClient(new WebChromeClient());
 basicView.getSettings().setDomStorageEnabled(true);
 basicView.loadUrl(targetPath);
 basicView.setWebViewClient(new HelloWebViewClient());

First of all AdvancedWebView configures all settings automatically on it's instantiating. Take a look on the sources here.

And the problem is that by default AdvancedWebView dissallow access using file:// scheme: 

    ...
    final WebSettings webSettings = getSettings();
    webSettings.setAllowFileAccess(false);
    setAllowAccessFromFileUrls(webSettings, false);
    webSettings.setBuiltInZoomControls(false);
    ...

So after creation of AdvancedWebView you need to add following lines:

 AdvancedWebView webView = (AdvancedWebView) findViewById(R.id.webView);
 webView.getSettings().setAllowFileAccess(true);
 if (Build.VERSION.SDK_INT >= 16) {
    webView.getSettings().setAllowFileAccessFromFileURLs(true);
    webView.getSettings().setAllowUniversalAccessFromFileURLs(true);
 }

NOTE: AdvancedWebView just subclassing WebView so it will not make any difference - the only difference that it configurating settings for you and handle some of the events.
