systeminfo api this specification defines interfaces and methods that provide web applications with access to various properties of a system this api also provides interfaces and methods that can retrieve statuses of hardware devices, get the value of selected properties, and subscribe to asynchronous notifications of changes for selected values web applications can use this api to access the following system properties battery build camera_flash since 2 4 cellular_network cpu device_orientation display ethernet_network since 2 4 locale since 2 1 memory since 2 3 network net_proxy_network
