Disable hotspot

Question

Android

Good afternoon!
There is a method for creating an access point:

public void createWifiAccessPoint() throws SocketException {
        if (wifiManager.isWifiEnabled()) {
            wifiManager.setWifiEnabled(false);
        }
        Log.d("Debug:getClass:", wifiManager.getClass().toString());
        Method[] wmMethods = wifiManager.getClass().getDeclaredMethods();
        boolean methodFound = false;
        for (Method method : wmMethods) {
            if (method.getName().equals("setWifiApEnabled")) {
                methodFound = true;
                WifiConfiguration netConfig = new WifiConfiguration();
                netConfig.SSID = name_ap;


                netConfig.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);

                netConfig.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
                netConfig.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
                netConfig.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
                netConfig.preSharedKey = key;
                try {
                    boolean apstatus = (Boolean) method.invoke(wifiManager, netConfig, true);
                    for (Method isWifiApEnabledmethod : wmMethods) {
                        if (isWifiApEnabledmethod.getName().equals("isWifiApEnabled")) {
                            while (!(Boolean) isWifiApEnabledmethod.invoke(wifiManager)) {
                            }
                            for (Method method1 : wmMethods) {
                                if (method1.getName().equals("getWifiApState")) {
                                    int apstate;
                                    apstate = (Integer) method1.invoke(wifiManager);
                                    Log.d("Debug:my", String.valueOf(apstate));
                                }
                            }
                        }
                    }
                    if (apstatus) {
                        Log.d("Debug:my", "Access Point created");
                    } else {
                        Log.d("Debug:my", "Access Point creation failed");
                    }
                } catch (IllegalArgumentException e) {
                    e.printStackTrace();
                } catch (IllegalAccessException e) {
                    e.printStackTrace();
                } catch (InvocationTargetException e) {
                    e.printStackTrace();
                }
            }
        }
        if (!methodFound) {
            Log.d("Debug:my", "cannot configure an access point");
        }
    }

That is, the setWifiApEnabled method of the WifiManager class is used through reflection.
The question is, how to turn off the access point ??

Answer 1

for (Method method : wmMethods)
  if (method.getName().equals("setWifiApEnabled"))
    method.invoke(wifiManager, netConfig, false);

Tried? Well, or null instead of netConfig?
