Here you can see an example of creating WebView for Android. Problem which I had was to load a local file. Simple answer is like this:

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

Where android_asset is actually assets folder in Android project. To add assets to the Android project, choose view to Android, right click on the app -> New -> Folder -> Assets folder:


Now the whole code can look something like this: 

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mWebView = (WebView) findViewById(R.id.activity_main_webview);
        WebSettings webSettings = mWebView.getSettings();
        webSettings.setJavaScriptEnabled(true);
        mWebView.loadUrl("file:///android_asset/touchEnd/index.html");
    }
