The correct url is   file    android asset RELATIVEPATH   where RELATIVEPATH is the path to your resource relative to the assets folder   Note the 3   s in the scheme  Web view would not load any of my assets without the 3  I tried 2 as  previously  commented by CommonsWare and it wouldn t work  Then I looked at CommonsWare s source on github and noticed the extra forward slash   This testing though was only done on the 1 6 Android emulator but I doubt its different on a real device or higher version   EDIT  CommonsWare updated his answer to reflect this tiny change  So I ve edited this so it still makes sense with his current answer

Works for WebView but seems to fail on URL openStream    So you need to distinguish file    protocols and handle them via AssetManager as suggested

Yeah you can t access your drive folder from you android phone or emulator because your computer and android are two different OS I would go for res folder of android because it has good resources management methods  Until and unless you have very good reason to put you file in assets folder  Instead You can do this   try         Resources res   getResources          InputStream in s   res openRawResource R raw yourfile          byte   b   new byte in s available           in s read b         String str   new String b         catch  Exception e          Log e LOG TAG   File Reading Error   e

There is no  absolute path for a file existing in the asset folder   The content of your project s assets  folder are packaged in the APK file  Use an AssetManager object to get an InputStream on an asset   For WebView  you can use the file Uri scheme in much the same way you would use a URL  The syntax for assets is file    android asset      note  three slashes  where the ellipsis is the path of the file from within the assets  folder

Finally  I found a way to get the path of a file which is present in assets from this answer in Kotlin  Here we are copying the assets file to cache and getting the file path from that cache file   Throws IOException  class      fun getFileFromAssets context  Context  fileName  String   File   File context cacheDir  fileName               also                  if   it exists                      it outputStream   use   cache - gt                      context assets open fileName  use   inputStream - gt                              inputStream copyTo cache                                                                             Get the path to the file like  val filePath    getFileFromAssets context   quot fileName extension quot   absolutePath
