  • You shouldn't have your web view auto refresh based on time. Timers in web-views is sort of taboo... It should refresh based on a trigger even if that trigger is an event from a server. – Eric Hodonsky Apr 16 '18 at 19:08

Could you just call WebView.loadUrl() every 2-3 seconds? That's what's suggested at https://stackoverflow.com/a/2563482/2848676

To schedule the recurring refresh you could use https://developer.android.com/reference/java/util/TimerTask.html
