android - 如何以编程方式在 Oreo 中创建 wifihotspot？

Question

你好鉴于link问题只是展示如何打开/关闭 wifi 热点，但我想添加使用 SSID 和密码创建 wifi 热点。我编写了用于在 android 中创建 wifihotspot(在 NONE 和 WPA2 PSK 中)的代码，它在 android 7 之前工作正常，但在 oreo 中它返回错误值。我的代码摘要是 -

private WifiManager wifiManager;
private Method method;
private WifiConfiguration config;
config.SSID = ssid;
config.status = WifiConfiguration.Status.ENABLED;
method = wifiManager.getClass().getMethod("setWifiApEnabled",                                           
WifiConfiguration.class, Boolean.TYPE);
boolean status = (Boolean)  method.invoke(wifiManager, config, true);

所以我的问题是如何为 android oreo 创建 NONE 和 WPA2 PSK 格式的 wifihotspot？可能吗？

零不支持以编程方式创建没有密码的热点。它总是使用随机生成的唯一 ssid 和 key 创建热点。

 WifiManager manager = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);
 WifiManager.LocalOnlyHotspotReservation mReservation;
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        assert manager != null;
        manager.startLocalOnlyHotspot(new WifiManager.LocalOnlyHotspotCallback() {

            @SuppressLint("SetTextI18n")
            @Override
            public void onStarted(WifiManager.LocalOnlyHotspotReservation reservation) {
                super.onStarted(reservation);
                Timber.d("Wifi Hotspot is on now , reservation is : %s", reservation.toString());
                mReservation = reservation;
                 key = mReservation.getWifiConfiguration().preSharedKey;
                 ussid = mReservation.getWifiConfiguration().SSID;


            }

            @Override
            public void onStopped() {
                super.onStopped();
                Timber.d("onStopped: ");
            }

            @Override
            public void onFailed(int reason) {
                super.onFailed(reason);
                Timber.d("onFailed: ");
            }
        }, new Handler());
    }
