Some content is best experienced fullscreen, like videos, games, image galleries, books, and slides in a presentation. This page shows how you can engage users more deeply with content in fullscreen and protect users from exiting the app accidentally.
You might be tempted to enable fullscreen mode just to maximize screen space for your app. But be mindful of how often users jump in and out of apps to check notifications, do impromptu searches, and more. Using fullscreen causes users to lose easy access to system navigation, so you should use fullscreen mode only when the benefit to the user experience goes beyond simply receiving a little extra space (such as to avoid accidental exits during a game or delivering a valuable immersive experience for images, videos, and books).
With Android Native Pro the full-screen mode can be enabled with few lines of code, as shown below:
using SA.Android.App.View; ... AN_ImmersiveMode.Enable();
