Display Full Screen Android API

Overview

This guide describes how to use Android's immersive mode to hide the status and navigation bars, enabling third-party applications to achieve a full-screen display.

Key Points

• Using Immersive Mode:

  • Immersive mode is a feature provided by Android that allows applications to hide the status bar and navigation bar for a full-screen experience.

• Limitation of Standard Immersive Mode:

  • In standard immersive mode, users can still pull down the status bar to view notifications and system messages.

• Enhancing Functionality with Permissions:

  • To prevent the status bar from appearing even when pulled down, you can enhance the immersive mode by adding specific permissions to your application.

  • After adding these permissions, the status bar will remain hidden, maintaining the full-screen mode without interruption.

Permission

 android.permission.CLOUDPOS_REAL_FULLSCREEN

The application declares permissions in the manifest.

Code snippet

//statusBar，navigationBar are all not display
getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN);

//statusBar is display, navigationBar is not display
getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_VISIBLE);
