Remarks

Request a network to satisfy a set of NetworkCapabilities.

This function behaves identically to the version that takes a NetworkCallback, but instead of NetworkCallback a PendingIntent is used. This means the request may outlive the calling application and get called back when a suitable network is found.

The operation is an Intent broadcast that goes to a broadcast receiver that you registered with Context#registerReceiver or through the <receiver> tag in an AndroidManifest.xml file

The operation Intent is delivered with two extras, a Network typed extra called #EXTRA_NETWORK and a NetworkRequest typed extra called #EXTRA_NETWORK_REQUEST containing the original requests parameters. It is important to create a new, NetworkCallback based request before completing the processing of the Intent to reserve the network or it will be released shortly after the Intent is processed.

If there is already a request for this Intent registered (with the equality of two Intents defined by Intent#filterEquals), then it will be removed and replaced by this one, effectively releasing the previous NetworkRequest.

The request may be released normally by calling #releaseNetworkRequest(android.app.PendingIntent).

It is presently unsupported to request a network with either NetworkCapabilities#NET_CAPABILITY_VALIDATED or NetworkCapabilities#NET_CAPABILITY_CAPTIVE_PORTAL as these NetworkCapabilities represent states that a particular network may never attain, and whether a network will attain these states is unknown prior to bringing up the network so the framework does not know how to go about satisfying a request with these capabilities.

To avoid performance issues due to apps leaking callbacks, the system will limit the number of outstanding requests to 100 per app (identified by their UID), shared with all variants of this method, of #registerNetworkCallback as well as ConnectivityDiagnosticsManager#registerConnectivityDiagnosticsCallback. Requesting a network with this method will count toward this limit. If this limit is exceeded, an exception will be thrown. To avoid hitting this issue and to conserve resources, make sure to unregister the callbacks with #unregisterNetworkCallback(PendingIntent) or #releaseNetworkRequest(PendingIntent).

This method requires the caller to hold either the android.Manifest.permission#CHANGE_NETWORK_STATE permission or the ability to modify system settings as determined by android.provider.Settings.System#canWrite.
