41.5 Adding Navigation Destinations

Remaining in the navigation graph it is now time to add the first destination. Since the project already has a fragment for the first screen (main_fragment.xml) this will be the first destination to be added to the graph. Click on the new destination button as shown in Figure 41-7 to select or create a destination:

Select main_fragment as the destination so that it appears within the navigation graph:

The home icon positioned above the destination node indicates that this is the start destination. This means that the destination will be the first displayed when the activity containing the NavHostFragment is created. To change the start destination to another destination, select that node in the graph and click on the home button located in the toolbar.
