android: load html content into WebView

        // case 1: load static html content under assets folder
        // you can have stylesheets or some external resources (e.g. image) as well
        WebView webView = (WebView)findViewById(R.id.webView1);
        webView.loadUrl("file:///android_asset/html/contentView.html");

        // case 2: load html file as template and replace with required content
        // IOUtils is a utility to read input stream into String
    try {
        String htmlContent = IOUtils.readInputStream(getAssets().open("html/contentView.html"));
            webView.loadDataWithBaseURL("file:///android_asset/html/", htmlContent.replace("{content}", "Your content"), "text/html", "utf-8", "about:blank");
    } catch (IOException e) {
        e.printStackTrace();
    }
    // need to manually set background color to transparent after load content
    webView.setBackgroundColor(Color.TRANSPARENT);
