As shown here it is possible to: 1. Create an Android WebView with setJavaScriptEnabled=true 2. Load a URL 3. Override onPageFinished and change the Web page displayed to the user
Now, is it possible for the Web page owner to implement anything server-side which prevents this from happening? The risk is that a malicious app could spoof the user by amending the Web page for nefarious means...
Many thanks!
