android不同版本（支持＞10）获取当前连接的wifi名称

1、AndroidManifest.xml 配置权限

2、手动申请权限

 在登录或首页activity中添加该方法，并在onCreate()方法中调用：

protected void applyPermission() {

        String[] permissions = {

                Manifest.permission.READ_EXTERNAL_STORAGE,

                Manifest.permission.INTERNET,

                Manifest.permission.ACCESS_NETWORK_STATE,

                Manifest.permission.MODIFY_AUDIO_SETTINGS,

                Manifest.permission.WRITE_EXTERNAL_STORAGE,

                Manifest.permission.WRITE_SETTINGS,

                Manifest.permission.READ_PHONE_STATE,

                Manifest.permission.ACCESS_WIFI_STATE,

                Manifest.permission.CHANGE_WIFI_STATE,

                Manifest.permission.CHANGE_NETWORK_STATE,

                Manifest.permission.RECORD_AUDIO,

                Manifest.permission.READ_CALENDAR,

                Manifest.permission.READ_CONTACTS,

                Manifest.permission.ACCESS_COARSE_LOCATION,

                Manifest.permission.ACCESS_FINE_LOCATION,

                Manifest.permission.WAKE_LOCK,

                Manifest.permission.CAMERA,

                Manifest.permission.MODIFY_PHONE_STATE,

                Manifest.permission.CHANGE_WIFI_MULTICAST_STATE

        };

        ArrayList toApplyList = new ArrayList();

        for (String perm : permissions) {

            if (PackageManager.PERMISSION_GRANTED != ContextCompat.checkSelfPermission(this, perm)) {

                toApplyList.add(perm);

                //进入到这里代表没有权限.

            }

        }

        String[] tmpList = new String[toApplyList.size()];

        if (!toApplyList.isEmpty()) {

            ActivityCompat.requestPermissions(this, toApplyList.toArray(tmpList), 1);

        }

    }

3、获取当前连接的wifi名称的方法

private void getConnectWifiSsid2(){    WifiManager mWifiManager = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);    //这里获取的是连接的wifi名称    String connect_wifi_name = mWifiManager.getConnectionInfo().getSSID().replace("\"", "");    Log.d("getConnectWifiSsid", "connect_wifi_name：" + connect_wifi_name); //打印全部wifi信息    Log.d("getConnectWifiSsid", "SSID：" + connect_wifi_name);      //打印SSID}

提示：APP安装完成之后，重启生效
