Previous work in ImageWallpaper cached the bitmap for a user to avoid reloading it (an expensive operation on large-display devices) when we could simply re-use it. User switching still caused a reload, however, since the place where we cache the bitmap (ImageWallpaper) is in an instance that is re-created on user-switch. A simple fix is to have the ImageWallpaper stop telling the WallpaperManager to erase its own cache of the bitmap prior to re-loading it. That step is unnecessary, since a bitmap that is cached can be assumed to be valid. A wallpaper change will correctly null out that cached version, so if the cached bitmap is non-null, then we can simply use it as-is. The fix is to remove the call to forgetLoadedWallpaper() and allow the caching mechanism to do its job. Issue #7986933 user switching on lock screen is slow (sometimes like molasses) Change-Id: I447754ab85337bc8ae59b4ad6c3e6c2b30e13735
