     * Registers to receive notifications about the best matching network which satisfy the given

     * {@link NetworkRequest}.  The callbacks will continue to be called until

     * either the application exits or {@link #unregisterNetworkCallback(NetworkCallback)} is

     * called.

     *

     * <p>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

     * {@link #registerNetworkCallback} and its variants and {@link #requestNetwork} as well as

     * {@link 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

     * {@link #unregisterNetworkCallback(NetworkCallback)}.

     * @param request {@link NetworkRequest} describing this request.

     *                        networks change state.

     * @param handler {@link Handler} to specify the thread upon which the callback will be invoked.

     * @throws RuntimeException if the app already has too many callbacks registered.
