Is it possible to do this simple software using HTML/Javascript and convert it to apk for smart TV?

I learned HTML/Javascript/CSS which are languages to build websites and .html files. I would like to build a simple app that checks the time and says the clock out loud every 30 minutes. It will be very helpful for my blind grandmother. I have no experience at all about java and making android apps. I downloaded Android Studio but it seems that I need to learn a lot of things before I do this simple app.

Is it possible to make it using HTML and JavaScript and convert it into apk? Will it run on a smart TV and work properly as if it is made with Android Studio?
