This is not exactly a tutorial but i do have a aia file which can help you make your 1st browser like the screenshot shown below
I created this browser where index.html file loads from asset folder. i used index.html as a home page for the browser so that a user can view landing page without INTERNET connection.
you can download the aia file from the given link below.
I am also adding some extra options like - Download, History, View Website Source Code, Make Browser Full Screen, Night Mode, Share App or Website URL, Bottom Sheet Menu, Google Voice Search and some more cool options.
if you want that browser then just post a comment here
and it will be great if you help me build my YouTube channel by subscribing. I will soon upload simple and short tutorial videos on that channel
