Demo of using BroadcastReceiver to monitor volume changes
Volume Button Demo
Demo of using BroadcastReceiver to monitor volume changes. Since Android 12 broke VolumeProviderCompat’s ability to receive volume button events when the screen is off (see https://issuetracker.google.com/issues/201546605), I created the VolumeButtonHelper class based on BroadcastReceiver and associated Service to bring back this functionality (see https://github.com/oliver11111/VolumeButtonDemo/tree/master/app/src/main/java/com/oliverClimbs/volumeButtonDemo)
Please note, since updating the UI from a service is beyond the scope of this demo application, volume change events are just logged to Android Studio’s Logcat window.
