# Configure edge-to-edge rendering

> Control the visibility of Android system bars, adjust their appearance and background, and extend your application content behind them for edge-to-edge rendering.

Control the visibility of Android system bars, adjust their appearance and background, and extend your application content behind them for edge-to-edge rendering. Configuring these options determines how your application utilizes the available device screen space.

## Configure edge-to-edge rendering with system bars

To configure edge-to-edge rendering, follow these steps:

1. In the Unity Editor, go to **Edit** > Editor > **Player** > **Android**.
2. In the **Resolution and Presentation** section, locate **System Bars**.
3. In the **System Bars** section, enable **Visible** for the system bar you want to display on screen.
4. Enable **Overlapping** to render your application content behind the visible system bar.
5. Set the **Appearance** setting for that system bar so its icons and text are legible against your application content.
6. In the **Background** dropdown, select **Transparent** so your application content displays through the bar.

Your application content now extends behind the system bars you configured for edge-to-edge rendering.

**Notes**:

* The **Visible** setting for the **Navigation Bars** replaces the deprecated **Hide Navigation Bar** Player setting. For existing projects with **Hide Navigation Bar** enabled, **Visible** for the **Navigation Bars** is disabled by default.
* The **Overlapping**, **Appearance**, and **Background** settings require Android 11 (API level 30) or later versions. These settings have no effect on Android 10 (API level 29) and earlier versions.
* The **Behavior** dropdown controls how a hidden system bar responds when the user swipes from the screen edge. The system bar can reappear temporarily and transparently or stays visible until you hide it again using [`AndroidWindowInsets.Hide`](/engine/6000.7/script-reference/unityengine/android/androidwindowinsets/hide.md).

## Control system bars at runtime

To control system bars dynamically while your application is running, use the [`AndroidWindowInsets`](/engine/6000.7/script-reference/unityengine/android/androidwindowinsets.md) class. This class provides methods to configure system bar visibility, overlapping, appearance, background transparency, and gesture behavior at runtime.

Use the [`AndroidApplication`](/engine/6000.7/script-reference/unityengine/android/androidapplication.md) class methods to access current Android system bars information.

* The [`currentWindowInsets`](/engine/6000.7/script-reference/unityengine/android/androidapplication/currentwindowinsets.md) property provides current Android system bars visibility and behavior status.
* The [`onWindowInsetsChanged`](/engine/6000.7/script-reference/unityengine/android/androidapplication/onwindowinsetschanged.md) event allows you to detect and handle any changes in the visibility and behavior at runtime.

> **Note:**
>
> The [`onWindowInsetsChanged`](/engine/6000.7/script-reference/unityengine/android/androidapplication/onwindowinsetschanged.md) callback is supported on Android 11 (API 30) or later versions. On older devices, you need to detect changes in the insets manually. These devices always return `undefined` when detecting the current Android system bar behavior.
