Project for Android using music player to transmit live data to the Mi Band and show them to screen in the band player
Customizing (and unlocking) Mi Band 5 could not be so easy and there are so many reason you wouldn't do it, including continue to use Mi Fit application.
For this reason I created a sketch of a Music Player using Media Notifications. It's just a workaround but works smoothly in my case.
To show how it works I push every 30 seconds stock data from Amazon AWS through the player
I loaded the example called "Stocksplayer". Just import it in your Android Studio and try it
