<h2 id="best-practices">Best practices</h2>
|
|
|
|
<p>The following list contains some helpful tips and best practices that will help you set up
|
|
and use Nearby effectively:
|
|
|
|
<ul>
|
|
<li>Use Nearby features sparingly and only when they're needed because they can consume battery
|
|
life quickly (up to 3.5 times faster than normal).
|
|
</li>
|
|
|
|
<li>Invoke Nearby explicitly with a button, switch, or special screen, and provide a visual
|
|
indication when the features are actively sending or receiving content.
|
|
</li>
|
|
|
|
<li>Ensure that users are aware of the data that is made visible by Nearby before
|
|
they start using the features.
|
|
</li>
|
|
|
|
<li>Stop any publish or subscribe operations when the user exits the app or stops the
|
|
activity that requires Nearby.
|
|
</li>
|
|
|
|
<li>Use the <em>earshot</em> option, which uses only the ultrasonic modem to send and receive
|
|
messages, to limit the range of Nearby messages to about five feet when privacy is important.
|
|
</li>
|
|
|
|
<li>Accelerate the exchange of messages (when appropriate) by making one device the publisher
|
|
only, and all other devices subscribers.
|
|
</li>
|
|
</ul>
