All this functionality is hidden behind a flag. If this flag is active, we disable the regular screenshots. Instead, we take a screenshot when an app transition for which a task is disappearing is starting. The screenshot gets stored into a gralloc buffer. SystemUI uses a new method to retrieve a snapshot gralloc buffer and then draws it using GraphicBuffer. createHardwareBitmap(). When starting an existing activity in an existing tasks, or when bringing an existing tasks to front from recents, we add a new snapshot starting window. For that, we reuse the existing starting window, but when creating the window, we use a fake window that draws the contents of the starting window.
