发布时间：2023-07-31作者：Topwo来源：原创点击：229

### 1、Android 8.0之前，打开wifi热点，使用反射机制
### 2、从Android 8.0开始往后，打开wifi热点，使用系统提供的api
```java
//打开
public static void openAP() {
    WifiManager wifiMgr = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
    wifiMgr.startLocalOnlyHotspot(new WifiManager.LocalOnlyHotspotCallback() {
        @Override
        public void onStarted(WifiManager.LocalOnlyHotspotReservation reservation) {
            mReservation = reservation;
            sid = reservation.getWifiConfiguration().SSID;
            pwd = reservation.getWifiConfiguration().preSharedKey;
            callbak.onConnected("", sid, pwd);
        }

@Override
        public void onStopped() {
            mReservation = null;
        }

@Override
        public void onFailed(int reason) {
            callbak.onConnected("wifi ap is failed to open", null, null);
        }
    }, new Handler());
}
//关闭
public static void closeAP() {
    if (mReservation != null) {
        mReservation.close();
        mReservation = null;
    }
}
```
