<p>Besides enabling communication with the cloud, Android's wireless APIs also
|
||
|
|
enable communication with other devices on the same local network, and even
|
||
|
|
devices which are not on a network, but are physically nearby. The addition of
|
||
|
|
Network Service Discovery (NSD) takes this further by allowing an application to
|
||
|
|
seek out a nearby device running services with which it can communicate.
|
||
|
|
Integrating this functionality into your application helps you provide a wide range
|
||
|
|
of features, such as playing games with users in the same room, pulling
|
||
|
|
images from a networked NSD-enabled webcam, or remotely logging into
|
||
|
|
other machines on the same network.</p>
|
||
|
|
<p>This class describes the key APIs for finding and
|
||
|
|
connecting to other devices from your application. Specifically, it
|
||
|
|
describes the NSD API for discovering available services and the Wi-Fi
|
||
|
|
Direct™ API for doing peer-to-peer wireless connections. This class also
|
||
|
|
shows you how to use NSD and Wi-Fi Direct in
|
||
|
|
combination to detect the services offered by a device and connect to the
|
||
|
|
device when neither device is connected to a network.
