virtually thats not potential. on iOS by no means, on Android there’s a method (seek for <activity-alias tag and switching app launcher icon), however is not desired to such typically adjustments, thus in all probability not environment friendly, not “device-friendly”. There’s a probability that Android itself or fork of it from some producer might restrict your app in such chance recognizing this conduct as impersonation
observe that app which might change icon oftenly is at all times a system app – clock, calendar, and many others. Such apps have particular privileges added to them by producers (Apple, Samsung, Xiaomi and many others.), not potential to be granted for frequent non-system apps. On Android you may set up a special “desktop app”, known as App launcher, and I guess these “dwell icons” aren’t engaged on a few of them, possibly all
For Android you could take into account App widget for oftenly-changed knowledge presentation, however even this characteristic have some limitation: “deafult” smallest refreshing interval is quarter-hour, efficiency causes ofc. however in right here you could ommit this limitation with personal refreshing mechanism primarily based e.g. on AlarmManager and/or WorkManager. Widget have been launched additionally for iOS, so it appears to be like thats a finest method for you
