How to implement Navigation Drawer with Bottom Navigation in the same application

In an app that has NavigationDrawer with Bottom Navigation , what would be the recommended path for implementation? I looked for tutorials and found neither in the official documentation. I created an app based on the NavigationDrawer model of Android Studio and then added it to BottomBar . I'm in doubt if BottomNavigationView should be added in content_main.xml , activity_main.xml or app_bar_main.xml . Is there any performance difference between the three options?
