For use cases that require high-bandwidth network 113 access, such as transporting large files or streaming media, we recommend that apps: 114 115 1. Check for an active network, and if there is one, check its bandwidth. 116 2. If there isn't an active network, or its bandwidth is insufficient, request access to an 117 unmetered Wi-Fi or cellular network. 118 3. If a high-bandwidth network is still not avaiable, ask the user to connect to a new Wi-Fi 119 network. 120 121 You can use the [ConnectivityManager][1] class to check if an active network exists, if the active 122 network has sufficient bandwidth for the desired network operation, and to request an appropriate 123 high-bandwidth network. 124 125 In addition to requesting a high-bandwidth network, you should also ensure that you are releasing 126 bound networks and cancelling any ongoing network requests when they are no longer needed. 127 128 This sample demonstrates all aspects of testing, requesting, and releasing network resources to 129 ensure a high-bandwidth network is available. In addition, the sample demonstrates the ideal user 130 experience for guiding the user through the process of acquiring a high-bandwidth network. 131 132 To try all aspects of this sample, ensure that you have removed all saved Wi-Fi networks from your 133 Wear device and that it is unplugged, as Wear devices may prefer high-bandwidth networks by default 134 while plugged-in. Also, you may wish to put your phone in airplane mode or turn off Bluetooth to 135 simulate the Wear device running standalone. 136 137 [1]: https://developer.android.com/reference/android/net/ConnectivityManager.html 138 ]]> 139 </intro> 140 </metadata> 141 </sample>
