Abstract: Embodiments disclosed herein may include a method. The method may include: querying, by a first device, a running status of a first application on the first device; storing, by the first device, application status information, wherein the application status information comprises a correspondence between an identifier of the first application and the running status of the first application; and sending, by the first device, the application status information to a second device when the first device is in a sleep state, to enable the second device to determine the running status of the first application.

Abstract: The disclosure provides example visual localization methods and devices. One method includes that a terminal device obtains an image of a building. The terminal device generates a descriptor based on the image. The descriptor includes information about a horizontal viewing angle between a first vertical feature line and a second vertical feature line in the image. The first vertical feature line indicates a first facade intersection line of the building, and the second vertical feature line indicates a second facade intersection line of the building. The terminal device performs matching in a preset descriptor database based on the descriptor, to obtain localization information of a photographing place of the image.
