I have a .html, .js, .css files on SDCARD, in my case html file contents are in encrypted form. I'm loading html file in following steps :
webView.loadDataWithBaseURL(relativePath, decFileContent, "text/html",
"utf-8", null );
relativePath = "file:///mnt/sdcard/MyFolder/"
"Sorry! your application not support to local storageError: SECURITY_ERR: DOM Exception 18"
Give the entire path of the HTML file, not just the directory path in relativePath.
Or you can also use loadUrl
