notification-channel-compat adds Notification Channels support to pre-Oreo Android devices. You use the same required coding as for the Android 8.0 built-in channel classes, with minimal change, to add channel support for your app, to any Android 4.0+ device. In Android 8.0+ it uses the built-in channel classes, and in pre-Android 8.0, it mimics them. This frees developer of dealing with notification preferences for older devices, and easily allowed multiple preferences for multiple channels.
