First of all your Webview is not used anywhere.. Create a Webview in your main.xml then init it by calling: 

  Webview webview = (Webview) findViewById(R.id.yourwebviewid);

And i think your url isnt correct, you should use something like:

  webview.loadUrl("file:///android_asset/index.html");

You are providing wrong url to webview. The url should be something like this:

wv.loadUrl("file:///android_asset/index.html");
