Abstract: Methods, systems, and apparatus are described for transferring application data. In one aspect, a method includes causing, by a first component on a first device to establish a wireless connection with a second device; receiving, from a second component on the second device, data specifying one or more applications that are installed on the second device and supported by the second component, each of the applications being separate from the second component; determining, by the first component, that a first application installed on the first device corresponds to one of the applications installed on the second device, the first application being separate from the first component; receiving, by the first component, first application data from the first application; and causing, by the first component, the first device to send the first application data to the second component running on the second device using the wireless connection.

Abstract: Methods, systems, and apparatus are described for transferring application data. In one aspect, a method includes causing, by a first service running on a first device to establish a wireless connection with a second device; receiving, from a second service running on the second device, data specifying applications that are installed on the second device and supported by the second service, each of the applications being separate from the second service; determining, by the first service, that a first application installed on the first device matches one of the applications installed on the second device, the first application being separate from the first service; receiving, by the first service, first application data from the first application; and causing, by the first service, the first device to send the first application data to the second service running on the second device using the wireless connection.

Abstract: Methods, systems, and apparatus are described for transferring application data between devices. In one aspect, a method includes causing, by a first service running on a first device, the first device to establish a wireless connection with a second device; receiving, from a second service running on the second device, data specifying applications that are installed on the second device and supported by the second service, each of the applications being separate from the second service; determining, by the first service, that a first application installed on the first device matches one of the applications installed on the second device, the first application being separate from the first service; receiving, by the first service, first application data from the first application; and causing, by the first service, the first device to send the first application data to the second service running on the second device using the wireless connection.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer-readable storage medium, and including a method for aggregating data rates. The method comprises identifying plural mobile devices configured for communication with a carrier-associated network for downloading network resources, and creating a data bundle representing data download capacity to be shared among mobile devices for data downloads from the network. The method further comprises negotiating a data bundle price with the carrier, and receiving requests from mobile devices for downloading network data. The method further comprises presenting data to a mobile device user that has provided a request, including rate information for initiating a download associated with the request, the rate information based on the negotiated price irrespective of airtime or data charges for the download ordinarily charged by the carrier. The method further comprises debiting a user account using a group price based on the rate information.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer-readable storage medium, and including a method for providing content. The method comprises receiving a request from a mobile device to load a resource and determining a transmission cost for loading the resource over a metered network. The method further comprises identifying sponsored content items for delivery with the resource, the sponsored content items being included in slots for presentation along with third-party content associated with the resource, each sponsored content item having an associated bid that represents an amount that will be paid by the sponsor for presentation of a given sponsored content item. The method further comprises determining a credit to be awarded toward load costs based on the bid, and providing a label that indicates a reduced cost to load the resource when a load of a resource is partially or entirely sponsored based on the credit.
