Answer 4

I am new to Andriod and have struggled with this. According to the Google WebView Reference Guide.

By default, WebView does not provide widgets like browsers, does not include JavaScript, and web page errors are ignored. If your goal is to display some HTML as part of your user interface, this is probably good; the user will not need to interact with the web page other than reading it, and the web page will not need to interact with the user. If you really want a full-blown web browser, then you probably want to call the Browser application using the Intent URL, rather than showing it using the WebView.

Sample code that I executed in MainActvity.java.

  Uri uri = Uri.parse("https://www.example.com"); Intent intent = new Intent(Intent.ACTION_VIEW, uri); startActivity(intent);
