There’s a working example of this in this project. It boils down to: In your assets/fonts folder, place the desired OTF or TTF font (here MyFont.otf) Create a HTML file that you’ll use for the WebView’s content, inside the assets folder (here inside assets/demo/my_page.html): <html> <head> <style type=”text/css”> @font-face { font-family: MyFont; src: url(“file:///android_asset/fonts/MyFont.otf”) } … Read more
myWebView.loadData(myHtmlString, “text/html; charset=UTF-8″, null); This works flawlessly, especially on Android 4.0, which apparently ignores character encoding inside HTML. Tested on 2.3 and 4.0.3.

I am not sure that you can even try-catch this one. I also believe that on many devices where there is no crash the users will experience occasional … Read more
It is possible to view a video element (video html5 tag) within a WebView, but I must say I had to deal with it for few days. These are the steps I had to follow so far: Find a properly encoded video When initializing the WebView, set the JavaScript, Plug-ins the WebViewClient and the WebChromeClient. … Read more
You can use this WebView browser = (WebView) findViewById(R.id.webview); browser.getSettings().setLoadWithOverviewMode(true); browser.getSettings().setUseWideViewPort(true); this fixes size based on screen size.

Here are 2 of them : This first is almost the same as yours, I guess we got it from the same tutorial. public class TestActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.webview); final WebView webview = (WebView) findViewById(R.id.browser); webview.getSettings().setJavaScriptEnabled(true); webview.addJavascriptInterface(new MyJavaScriptInterface(this), “HtmlViewer”); webview.setWebViewClient(new WebViewClient() … Read more
