How to transfer files via hotspot?

File transfer through hotspot

This project transfers files through wifi to pc.

I want to sent the files through both wifi and hotspot.

This shares files with wifi IP.

public static String getWifiIp(@NonNull Context context) {
    WifiManager wifimanager = (WifiManager) context.getApplicationContext().getSystemService
            (Context.WIFI_SERVICE);
    if (wifimanager == null) {
        return null;
    }
    WifiInfo wifiInfo = wifimanager.getConnectionInfo();
    if (wifiInfo != null) {
        return intToIp(wifiInfo.getIpAddress());
    }
    return null;
    }

    private static String intToIp(int i) {
    return (i & 0xFF) + "." + ((i >> 8) & 0xFF) + "." + ((i >> 16) & 0xFF) + "." + ((i >> 24)
            & 0xFF);
    }

     public static NetworkInfo.State getWifiConnectState(Context context) {
     ConnectivityManager manager = (ConnectivityManager) context.getSystemService(Context
            .CONNECTIVITY_SERVICE);
    if (manager == null) {
        return NetworkInfo.State.DISCONNECTED;
    }
    NetworkInfo mWiFiNetworkInfo = manager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
    if (mWiFiNetworkInfo != null) {
        return mWiFiNetworkInfo.getState();
    }
    return NetworkInfo.State.DISCONNECTED;
   }

This code used to get the IP address of wifi. I want to share files through both wifi and hotspot. So, I replaced this code to get both wifi and hotspot IP.

public void getDeviceIpAddress() {
	try {

		for (Enumeration<NetworkInterface> enumeration = NetworkInterface
				.getNetworkInterfaces(); enumeration.hasMoreElements();) {
			NetworkInterface networkInterface = enumeration.nextElement();
			for (Enumeration<InetAddress> enumerationIpAddr = networkInterface
					.getInetAddresses(); enumerationIpAddr
					.hasMoreElements();) {
				InetAddress inetAddress = enumerationIpAddr.nextElement();
				if (!inetAddress.isLoopbackAddress()
						&& inetAddress.getAddress().length == 4) {
					tvServerIP.setText(inetAddress.getHostAddress());
				}
			}
		}
	} catch (SocketException e) {
		Log.e("ERROR:", e.toString());
	}
}

I tried with this code, but it didn't work.

How can I do this?
