Firebase Data Logging Display App (Gauges, Charts, and Table)

Hello, I am following

To display data from Firebase in Gauges, Charts, and Table.
How can I make android app for it? I have below ideas in mind

Use as is with android app to display web page, but here its hard to get notification when some data gets changes, with this approach we will interact only when app in open.
develop android app to display data from firebase in Gauges, Charts, and Table, I could not find matching app or links to make it.

Could you please redirect me to appropriate material or demo app?
