AudioBytes

AI-generated Key Takeaways

• This class is deprecated as Nearby Messages will no longer support audio.

• AudioBytes represents a message sent over near-ultrasound audio with a byte array payload limited by MAX_SIZE.

• The class provides methods to convert between AudioBytes and Nearby Messages for publishing and subscribing data over audio.

• The maximum size of the audio message payload is defined by the constant MAX_SIZE, which is 10 bytes.

public final class AudioBytes extends Object

This class is deprecated.
Nearby Messages will no longer support audio.

A message that will be sent directly over near-ultrasound audio. The payload can be an arbitrary byte[] array limited in size as given by MAX_SIZE.

Use this in combination with the Messages API to send or receive data over audio. For instance, the toMessage() method can be used to fetch a Nearby Message object for a Messages.publish(GoogleApiClient, Message) call.

Similarly, the from(Message) method can be used to convert a Message obtained from a subscribe call to an AudioBytes object.
