If your structure should be like this    assets html index html   assets scripts index js   assets css index css  Then just do   Android WebView  handling orientation changes        if WebViewStateHolder INSTANCE getBundle      null      this works only on single instance of webview  use a map with TAG if you need more         webView loadUrl  file    android asset html index html          else           webView restoreState WebViewStateHolder INSTANCE getBundle             Make sure you add      WebSettings webSettings   webView getSettings        webSettings setJavaScriptEnabled true       webSettings setJavaScriptCanOpenWindowsAutomatically true       if android os Build VERSION SDK INT  gt   android os Build VERSION CODES JELLY BEAN            webSettings setAllowFileAccessFromFileURLs true           webSettings setAllowUniversalAccessFromFileURLs true           Then just use urls   lt html gt   lt head gt       lt meta charset  utf-8  gt       lt title gt Zzzz lt  title gt       lt script src     scripts index js  gt  lt  script gt       lt link rel  stylesheet  type  text css  href     css index css  gt

You could read the html file manually and then use loadData or loadDataWithBaseUrl methods of WebView to show it

ok  that was my very stupid mistake  I post the answer here just in case someone has the same problem   The correct path for files stored in assets folder is file    android asset    with no  s  for assets folder which i was always thinking it must have a  s     And  mWebView loadUrl  file    android asset myfile html    works under all API levels   I still not figure out why mWebView loadUrl  file    android res raw myfile html    works only on API level 8  But it doesn t matter now

The debug compilation is different from the release one  so   Consider your Project file structure like that  this case if for a Debug assemble    src       debug               assets                         index html   You should call index html into your WebView like   web loadUrl  file    android asset index html      So forth  for the Release assemble  it should be like   src       release                   assets                             index html      The bellow structure also works  for both compilations  debug and release     src       main             assets                       index html
