Ok so the image i\'m using is called test.png and I have a java class (Cherry.java) and a xml class (cherry.xml) Also I have a html file in the /res/raw folder called htmlt
First of all welcome to stackoverflow.
Now put your html and image etc inside the Assets folder. And use the following code.
Cherry.java
WebView webview = (WebView) findViewById(R.id.abtus_webView);
webview.loadUrl("file:///android_asset/index.html");
htmltest.html
I have put the images into the images Folder in Assets folder.This is working for me correct,I hope it helps you.
