Android10自动连接WiFi问题的解决

/**
   * Add a new network description to the set of configured networks.
   * The {@code networkId} field of the supplied configuration object
   * is ignored.
   * <p/>
   * The new network will be marked DISABLED by default. To enable it,
   * called {@link #enableNetwork}.
   *
   * @param config the set of variables that describe the configuration,
   *      contained in a {@link WifiConfiguration} object.
   *      If the {@link WifiConfiguration} has an Http Proxy set
   *      the calling app must be System, or be provisioned as the Profile or Device Owner.
   * @return the ID of the newly created network description. This is used in
   *     other operations to specified the network to be acted upon.
   *     Returns {@code -1} on failure.
   *
   * @deprecated
   * a) See {@link WifiNetworkSpecifier.Builder#build()} for new
   * mechanism to trigger connection to a Wi-Fi network.
   * b) See {@link #addNetworkSuggestions(List)},
   * {@link #removeNetworkSuggestions(List)} for new API to add Wi-Fi networks for consideration
   * when auto-connecting to wifi.
   * <b>Compatibility Note:</b> For applications targeting
   * {@link android.os.Build.VERSION_CODES#Q} or above, this API will always return {@code -1}.
