Android WearHighBandwidthNetworking Sample

Sample demonstrates how to determine if a high-bandwidth network is available for use cases that require a minimum network bandwidth, such as streaming media or downloading large files. In addition, the sample demonstrates best practices for asking a user to add a new Wi-Fi network for high-bandwidth network operations if the bandwidth of currently available networks is inadequate.

Introduction

On Wear, a high-bandwidth network is not always available, as the platform manages network connectivity with the goal of providing the best overall user experience, balancing network bandwidth and maximizing device battery life. For use cases that require high-bandwidth network access, such as transporting large files or streaming media, we recommend that apps:

  1. Check for an active network, and if there is one, check its bandwidth.
  2. If there isn't an active network, or its bandwidth is insufficient, request access to an unmetered Wi-Fi or cellular network.
  3. If a high-bandwidth network is still not avaiable, ask the user to connect to a new Wi-Fi network.

You can use the ConnectivityManager class to check if an active network exists, if the active network has sufficient bandwidth for the desired network operation, and to request an appropriate high-bandwidth network.

In addition to requesting a high-bandwidth network, you should also ensure that you are releasing bound networks and cancelling any ongoing network requests when they are no longer needed.

This sample demonstrates all aspects of testing, requesting, and releasing network resources to ensure a high-bandwidth network is available. In addition, the sample demonstrates the ideal user experience for guiding the user through the process of acquiring a high-bandwidth network.

To try all aspects of this sample, ensure that you have removed all saved Wi-Fi networks from your Wear device and that it is unplugged, as Wear devices may prefer high-bandwidth networks by default while plugged-in. Also, you may wish to put your phone in airplane mode or turn off Bluetooth to simulate the Wear device running standalone.
