Answer 2

As an option, make your application with 1 WebView component, from which you can already manage what and how it works.
If you completely refuse links to external resources, do a timer on the page to go to the main page, then, in fact, you may not need anything else (except for the prohibition of hardware buttons, but they have already been mentioned).

Answer 3

Once a minute, set a cookie with a timestamp with a Javascript, while checking its existence and the timestamp. If the difference between now() and cookie <> 60 close the tab. When you open the page, do the check too.

Answer 4

There is no Android at hand, but there is a bare idea. If the /etc/hosts and /etc/resolv.conf files remain in it from Linux, then by changing them as follows, you can achieve your desire. where sitename is the name of the desired site, 8.8.8.8 is its ip address . Thus, the client will not have access to sites by name (but will be able to access by ip address), except for what is registered in hosts.
===cat /etc/resolv.conf===
nameserver 127.0.0.1
==========================
===cat /etc/resolv.conf===
8.8.8.8 sitename
==========================
