<p>With Wear OS by Google, a watch can communicate with a network directly, without access to an Android or iOS phone. Don't use the Data Layer API to connect a Wear OS app to a network. Instead, follow the guidelines and steps in this guide.</p> <h2 id="network-access" data-text="Network access" tabindex="-1">Network access</h2> <p>Wear OS apps can make <a href="/guide/topics/connectivity">network requests</a>. When a watch has a Bluetooth connection to a phone, the watch's network traffic is generally proxied through the phone.</p> <p>When a phone is unavailable, Wi-Fi and cellular networks are used, depending on the watch hardware. The Wear OS platform handles transitions between networks.</p> <p>You can use protocols such as HTTP, TCP, and UDP. However, the <a href="/reference/android/webkit/package-summary"><code translate="no" dir="ltr">android.webkit</code></a> APIs, including the <a href="/reference/android/webkit/CookieManager"><code translate="no" dir="ltr">CookieManager</code></a> class, are not available. You can use cookies by reading and writing headers on requests and responses.</p> <p>Use <a href="/topic/libraries/architecture/workmanager"><code translate="no" dir="ltr">WorkManager</code></a> for asynchronous requests, including polling at regular intervals.</p> <p>If you need to connect to specific network types, see <a href="/training/basics/network-ops/reading-network-state">Reading network state</a>.</p> <h2 id="high-bandwidth-network-access" data-text="High-bandwidth network access" tabindex="-1">High-bandwidth network access</h2> <p>The Wear OS platform manages network connectivity with the goal of providing the best overall user experience. The platform chooses the default active network by balancing two needs: long battery life and network bandwidth.</p> <p>When battery preservation is prioritized, the active network might not have enough bandwidth for network tasks like transporting large files or streaming media.</p> <p>This section provides guidance on using the <a href="/reference/android/net/ConnectivityManager"><code translate="no" dir="ltr">ConnectivityManager</code></a> class to help ensure that your app has the network bandwidth it needs. For general information about fine-grained control over network resources, see <a href="/training/basics/network-ops/managing">manage network usage</a>.</p> <h3 id="requesting-wifi-connectivity" data-text="Request Wi-Fi connectivity" tabindex="-1">Request Wi-Fi connectivity</h3> <p>For use cases that require high-bandwidth network access, such as transporting large files or streaming media, request connectivity with a high-bandwidth transport, such as Wi-Fi.

Refer to the existing documentation about <a href="/training/basics/network-ops/connecting">connecting to a network</a> and <a href="https://firebase.google.com/docs/cloud-messaging/">cloud messaging</a>.</p> <p>FCM works well with <a href="/training/monitoring-device-state/doze-standby">Doze</a> and is the recommended way to send notifications to a watch.</p> <p>Provide for messages from FCM by collecting a registration token for a device when your Wear OS app runs. Then include the token as part of the destination when your server sends messages to the FCM REST endpoint. FCM sends messages to the device identified by the token.</p> <p>An FCM message is in JavaScript Object Notation (JSON) format and can include one or both of the following payloads:</p> <ul> <li><strong>Notification payload:</strong> when a notification payload is received by a watch, the data displays to a user directly in the notification stream. When the user taps the notification, your app launches.</li> <li><strong>Data payload:</strong> when the payload has a set of custom key or value pairs. The payload is delivered as data to your Wear OS app.</li> </ul> <p>For more information and examples of payloads, see <a href="https://firebase.google.com/docs/cloud-messaging/concept-options">About FCM messages</a>.</p> <p>By default, notifications are bridged from a phone app to a watch. If you have a standalone Wear OS app and a corresponding phone app, duplicate notifications can occur. For example, a single <a href="/training/wearables/notifications/creating">notification</a> from FCM, received by both a phone and a watch, could be displayed by both devices independently. You can prevent this by using <a href="/training/wearables/notifications/bridger">bridging APIs</a>.</p> <h2 id="background-services" data-text="Use background services" tabindex="-1">Use background services</h2> <p>To help ensure that background tasks are correctly executed, they must account for <a href="/training/monitoring-device-state/doze-standby">Doze</a> and App Standby.</p> <p>When a screen turns off or enters ambient mode for a long enough time, a subset of Doze can occur, and background tasks can be deferred for certain periods. Later, when the device is stationary for an extended time, regular Doze occurs. Schedule requests with the <a href="/topic/libraries/architecture/workmanager"><code translate="no" dir="ltr">WorkManager</code></a> API, which lets your app register for Doze-safe code execution.</p> <h3 id="schedule-with-constraints" data-text="Schedule with constraints" tabindex="-1">Schedule with constraints</h3> <p>You can use constraints to configure requests in a way that preserves battery life. Select one or more of the following constraints to include in your requests:</p> <ul> <li><p>Schedule a request that requires networking.</p> <p>Specify whether the <a href="/reference/androidx/work/NetworkType"><code translate="no" dir="ltr">NetworkType</code></a> is <code translate="no" dir="ltr">CONNECTED</code> or <code translate="no" dir="ltr">UNMETERED</code>. <code translate="no" dir="ltr">UNMETERED</code> is for large data transfers, while <code translate="no" dir="ltr">CONNECTED</code> is for small transfers.</p></li> <li><p>Schedule a request while charging.</p></li> <li><p>Schedule a request while the device is idle.
