On some devices, it is possible that config_enableWallpaperService is false, in which then there is no wallpaper service on device. Calling WallpaperManager#getWallpaperId will then result in an NPE. We should just do a check and return false. Bug: 62387789 Test: RoboSettingsTest Change-Id: I31db6845f06533d92140bf91d0f7fc7e7bedc5c5
