| NormalApp | 1 | The windowing layer for normal application windows. If an application does not explicitly request a windowing layer for its task, it is considered to be in this layer. Requesting this layer using AppTask.requestWindowingLayer is typically done to exit a previously requested layer.

| Pinned | 2 | The windowing layer for pinned windows. These windows are typically displayed above normal application windows. To ensure system integrity and a consistent user experience, the system imposes several restrictions on tasks using this layer. These may include, but are not limited to: Forcing the task to be completely opaque and display system decorations; Strictly limiting the number of tasks in this layer (e.g., only one at a time); Limiting the application's control over the task's size and position; Limiting the maximum window size to which the user can resize the task; Making the task non-movable programmatically (including restrictions on workarounds like resizing); Providing users with immediate settings access to disable the feature; Providing users with a way to close the window; The task may be finished by the system if it can no longer be hosted on this layer due to windowing changes; The available display modes may be limited for tasks on this layer. These may include, but are not limited to: Picture-in-Picture mode, Split-screen mode, and fullscreen This layer might be shared with Picture-in-Picture (PiP) tasks; therefore, tasks on this layer might be dismissed when another enters PiP. The task's window on this layer has the following requirements:; Must be opaque; Must have affordances to close the window and to allow users to disable showing and running tasks on this layer, per app; Must have a minimum size of 220dp according to the established Multi-windows CDD requirements; The task cannot change to another layer unless requested by the app with a call to AppTask.requestWindowingLayer.
