Android Webview mit WebGL

Question

Ich versuche, es aus den letzten paar Stunden zu finden und konnte nicht getan werden.

Ausgabe: Ich habe eine HTML-Seite und eine WebGL-Datei (three.js-Datei). Ich muss diese HTML-Datei in Android Webview öffnen. WebView konnte die HTML-Seite nicht laden.

Unten finden Sie den Code, der i

 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"); 

ich meine Ressourcen gelegt hatte alle in sdcard versucht haben.

Fehlerprotokoll:

versuchen, auf den folgenden Einstellungen drehen:

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