The first thing you need to do when building an app is to create an empty placeholder for it. You create the app placeholder from the hub.
Do the following:
- Click Create new app in the hub.
- Give your app a name.
The app is created.
Click Open app.
The app opens in the app overview.
The next step is to add data to the new app.
For information about how to add data, see Adding data to the app.
