For use cases that require high-bandwidth network 117access, such as transporting large files or streaming media, we recommend that apps: 118 1191. Check for an active network, and if there is one, check its bandwidth. 1202. If there isn't an active network, or its bandwidth is insufficient, request access to an 121unmetered Wi-Fi or cellular network. 1223. If a high-bandwidth network is still not avaiable, ask the user to connect to a new Wi-Fi 123network. 124 125You can use the [ConnectivityManager][1] class to check if an active network exists, if the active 126network has sufficient bandwidth for the desired network operation, and to request an appropriate 127high-bandwidth network. 128 129In addition to requesting a high-bandwidth network, you should also ensure that you are releasing 130bound networks and cancelling any ongoing network requests when they are no longer needed. 131 132This sample demonstrates all aspects of testing, requesting, and releasing network resources to 133ensure a high-bandwidth network is available. In addition, the sample demonstrates the ideal user 134experience for guiding the user through the process of acquiring a high-bandwidth network. 135 136To try all aspects of this sample, ensure that you have removed all saved Wi-Fi networks from your 137Wear device and that it is unplugged, as Wear devices may prefer high-bandwidth networks by default 138while plugged-in. Also, you may wish to put your phone in airplane mode or turn off Bluetooth to 139simulate the Wear device running standalone. 140 141[1]: https://developer.android.com/reference/android/net/ConnectivityManager.html 142]]> 143 </intro> 144 </metadata> 145</sample>
