 If there's a requirement to let an animation complete in the background, then the `await` operator can be omitted. In this scenario, the animation extension methods will quickly return after initiating the animation, with the animation occurring in the background. This operation can be taken advantage of when creating composite animations. For more information, see [Composite animations](#composite-animations).

 ## Single animations
 
 Each extension method in the <xref:Microsoft.Maui.Controls.ViewExtensions> class implements a single animation operation that progressively changes a property from one value to another value over a period of time.

 ## Create an animation
 
 When creating an <xref:Microsoft.Maui.Controls.Animation> object, typically, a minimum of three parameters are required, as demonstrated in the following code example:

+On Android, animations respect the system animation settings:
+
+- If the system's animations are disabled (either by accessibility features or developer features), new animations will jump immediately to their finished state.
+- If the device's power saving mode is activated while animations are in progress, the animations will immediately jump to their finished state.
+- If the device's animation durations is set to zero (disabled) while animations are in progress and the API version is 33 or greater, the animations will immediately jump to their finished state.

 - It's not required to specify a value for the `$(ApplicationIdGuid)` build property in your app's project file. This is because .NET MAUI Windows apps no longer require a GUID as an app ID, and instead use the value of the `$(ApplicationId)` build property as the app ID. Therefore, the same reverse domain format app ID is now used across all platforms, such as com.mycompany.myapp.
 - .NET MAUI Mac Catalyst apps are no longer limited to 50 menu items on the menu bar.
 - The `PlatformImage.FromStream` method, in the `Microsoft.Maui.Graphics` namespace, can now be used to load images on Windows instead of having to use the `W2DImageLoadingService` class.
+- On Android, animations respect the system animation settings. For more information, see [Basic animation](~/user-interface/animation/basic.md).
