I am using Android Studio UDP DatagramSocket. Using a generator, I collected Java files. I can not decode messages. Maybe there is a working example on Android Studio?

    private class UdpServerThread extends Thread{
        int serverPort;
        DatagramSocket socket;
        boolean running;
        public UdpServerThread(int serverPort) {
            super();
            this.serverPort = serverPort;
        }
        public void setRunning(boolean running){ this.running = running;}

        @Override
        public void run() {
            running = true;
            try {
                socket = new DatagramSocket(serverPort);
                Log.e(TAG, "UDP Server is running");

                while(running){
                    byte[] buf = new byte[256];

                    DatagramPacket packet = new DatagramPacket(buf, buf.length);
                    socket.receive(packet);
                    String modifiedSentence = new String(packet.getData());
                    InetAddress address2 = packet.getAddress();
                    int port = packet.getPort();
                    String str = new String(packet.getData(), packet.getOffset(), packet.getLength());

                    Parser parser = new Parser();
                    MAVLinkPacket MAVpacket = null;
                    MAVLinkMessage msg;

                    //for (int i = 0; i < buf.length - 1; i++) {
                    for (byte b : packet.getData()) {
                        MAVpacket = parser.mavlink_parse_char(b & 0x00ff);
                        if (MAVpacket != null) {
                            msg = MAVpacket.unpack();
                            switch (msg.msgid) {
                                case msg_gamepad_button_press_event.MAVLINK_MSG_ID_GAMEPAD_BUTTON_PRESS_EVENT:
                                    Log.d(LOG_TAG, "***Get data: " + msg.msgid + "***"  );
                                break;

                            default:

                            }
                        }
                    }

                }

                Log.e(TAG, "UDP Server ended");

            } catch (SocketException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            } finally {
                if(socket != null){
                    socket.close();
                    Log.e(TAG, "socket.close()");
                }
            }
        }
    }
