1448 <h3>Wi-Fi Network Service Discovery</h3>
1450 <p>Android 4.1 introduces support for multicast <strong>DNS-based service discovery</strong>, which lets applications find and connect to services offered by peer devices over Wi-Fi networks — including mobile devices, printers, cameras, media players, and others. Developers can take advantage of Wi-Fi network service discovery to build cross-platform or multiplayer games and application experiences.</p>
1452 <p>Using the service discovery API, apps can create and register any kind of service, for any other NSD-enabled device to discover. The service is advertised by multicast across the network using a human-readable string identifier, which lets user more easily identify the type of service. </p>
1454 <p>Consumer devices can use the API to scan and discover services available from devices connected to the local Wi-Fi network. After discovery, apps can use the API to resolve the service to an IP address and port through which it can establish a socket connection.</p>
1458 <h3>Wi-Fi P2P Service Discovery</h3>
1469 <p>Android 4.1 takes Wi-Fi P2P further, adding API support for <strong>pre-associated service discovery</strong>. Pre-associated service discovery lets your apps get more useful information from nearby devices about the services they support, before they attempt to connect. Apps can initiate discovery for a specific service and filter the list of discovered devices to those that actually support the target service or application.</p>
1471 <p>For example, this means that your app could discover only devices that are ?printers? or that have a specific game available, instead of discovering all nearby Wi-Fi P2P devices. On the other hand, your app can advertise the service it provides to other devices, which can discover it and then negotiate a connection. This greatly simplifies discovery and pairing for users and lets apps take advantage of Wi-Fi P2P more effectively.</p>
1473 <p>With Wi-Fi P2P service discovery, you can create apps and <strong>multiplayer games</strong> that can share photos, videos, gameplay, scores, or almost anything else — all without requiring any Internet or mobile network. Your users can connect using only a direct p2p connection, which avoids using mobile bandwidth.</p>
