This simple app turns your Android phone into a Notification Channels Demo App.
To use this app the user just clicks the 'Notification Channels Demo' app icon and they are taken right into the app. They are greeted with 'Title' and 'Content' lines for entering the required information. Once the user clicks one of the lines a keyboard pops up and they can fill in the information. Then when they are done they can collapse the keyboard and click the 'Send Notification' button to create a notification. Notifications when made are shown as a white filled in circle in the upper left hand corner. Users can pull down the notification Message and view the contents. Afterwards they can select the 'Clear All' button and clear all the notifications and come back to the start screen.
