wish of those help Try creating a web pages in your assets directory and creating HTML pages that display the images. Then call a web page using this:
code :
webview.loadUrl("file:///android_asset/blacksmoke.html");
loadDataWithBaseUrl("content://<your contentProvider>/blacksmoke.html", ...);
<!DOCTYPE html>
<!-- Perhaps some JQuery mobile for more functionality and control over which images get displayed and why etc -->
  <body>
     <div><img src="image/blacksmoke1.jpg"></div>
  </body>
</html>

this will help Turns out this error was caused by having images that are larger than 1500px in width. After scaling them down, the error disappears. Must be a problem with the Android webview, I guess.

Does that help You don't need to put ms-appx:/// before the image name in the source of the html image.
If you have the image in the same folder of the html, the code would be like this:
