		<p>Provides APIs for RTP (Real-time Transport Protocol), allowing applications to manage on-demand
		or interactive data streaming. In particular, apps that provide VOIP, push-to-talk, conferencing,
		and audio streaming can use these APIs to initiate sessions and transmit or receive data streams
		over any available network.</p>

		<p>To support audio conferencing and similar usages, you need to instantiate two classes as
		endpoints for the stream:</p>

		<ul>
		<li>{@link android.net.rtp.AudioStream} specifies a remote endpoint and consists of network mapping
		and a configured {@link android.net.rtp.AudioCodec}.</li>

		<li>{@link android.net.rtp.AudioGroup} represents the local endpoint for one or more {@link
		android.net.rtp.AudioStream}s. The {@link android.net.rtp.AudioGroup} mixes all the {@link
		android.net.rtp.AudioStream}s and optionally interacts with the device speaker and the microphone at
		the same time.</li>
		</ul>

		<p>The simplest usage involves a single remote endpoint and local endpoint. For more complex usages,
		refer to the limitations described for {@link android.net.rtp.AudioGroup}.</p>

		<p class="note"><strong>Note:</strong> To use the RTP APIs, you must request the {@link
		android.Manifest.permission#INTERNET} and {@link
		android.Manifest.permission#RECORD_AUDIO} permissions in your manifest file.</p>
