如何在Android Marshmallow中创建wifi网络共享热点？

我尝试使用以下代码在Android Marshmallow中创建wifi tethering Hotspot.

public class WifiAccessManager {

    private static final String SSID = "1234567890abcdef";

    public static boolean setWifiApState(Context context, boolean enabled) {
        //config = Preconditions.checkNotNull(config);
        try {
            WifiManager mWifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
            if (enabled) {
                mWifiManager.setWifiEnabled(false);
            }
            WifiConfiguration conf = getWifiApConfiguration();
            mWifiManager.addNetwork(conf);

            return (Boolean) mWifiManager.getClass().getMethod("setWifiApEnabled", WifiConfiguration.class, boolean.class).invoke(mWifiManager, conf, enabled);
        } catch (Exception e) {
            e.printStackTrace();
            return false;
        }
    }

    public static WifiConfiguration getWifiApConfiguration() {
        WifiConfiguration conf = new WifiConfiguration();
        conf.SSID = SSID;
        conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
        return conf;
    }
}

}

但它显示以下权限问题..

java.lang.SecurityException: googleplus.tarun.info.hotspotcreation was not granted  either of these permissions: android.permission.CHANGE_NETWORK_STATE, android.permission.WRITE_SETTINGS.

但我已经在清单上添加了那些..

我该如何解决这个问题？
