You need to go to "Settings", click on "WiFi", select the current network to which the smartphone is connected, tap on "Proxy settings". And then - deactivate the item.

Selenium WebDriver primarily supports locating elements using a variety of locator strategies such as ID, class name, tag name, name, xpath, and CSS selector. However, jQuery locators are not directly supported in Selenium WebDriver by default.

If you want to use jQuery selectors to locate elements, you have a few options

1. Execute jQuery Commands with JavaScript

You can execute JavaScript code, including jQuery, using the execute_script method in Selenium WebDriver. This allows you to leverage jQuery selectors to find elements.

from selenium import webdriver

driver = webdriver.Chrome()
driver.get("https://example.com")

# Example: Using jQuery to find an element by class name
element = driver.execute_script("return $('.your-class-name')[0];")

# Interact with the element
element.click()

driver.quit()

In this example, replace $('.your-class-name')[0]; with your actual jQuery selector.

2. Use WebDriver's Built-in Locators

In most cases, you can achieve the same result using Selenium WebDriver's built-in locator strategies without relying on jQuery. For example, to locate an element by class name:

from selenium import webdriver

driver = webdriver.Chrome()
driver.get("https://example.com")

# Example: Using WebDriver's built-in class name locator
element = driver.find_element_by_class_name("your-class-name")

# Interact with the element
element.click()

driver.quit()

Use CSS selectors, XPath, or other supported locators based on your specific needs.

Using the built-in WebDriver locators is generally recommended as it avoids the need to include jQuery and simplifies your code. However, if you have a specific reason to use jQuery, you can resort to executing JavaScript code as demonstrated in the first option.

To receive and display a video stream via UDP protocol on a C# server, you can use the UdpClient class from the System.Net.Sockets namespace. Here's a simple example of how to set up a UDP server that receives a video stream and displays it on a Windows Forms application:

1. Create a new Windows Forms Application project in Visual Studio.

2. Add a PictureBox control to the form.

3. Double-click on the PictureBox to create a new method named pictureBox1_Click.

4. Add the following code to the pictureBox1_Click method:

using System;
using System.Drawing;
using System.Net;
using System.Net.Sockets;
using System.Threading;
using System.Windows.Forms;

namespace UDP_Video_Stream
{
    public partial class Form1 : Form
    {
        private const int Port = 12345;
        private byte[] _buffer = new byte[1024 * 1024]; // 1MB buffer
        private UdpClient _udpClient;
        private Thread _receiveThread;

        public Form1()
        {
            InitializeComponent();
            InitializeUdpClient();
        }

        private void InitializeUdpClient()
        {
            _udpClient = new UdpClient(Port);
            _udpClient.EnableBroadcast = true;
            _receiveThread = new Thread(ReceiveVideoStream);
            _receiveThread.Start();
        }

        private void ReceiveVideoStream()
        {
            while (true)
            {
                try
                {
                    IPEndPoint remoteEndPoint = new IPEndPoint(IPAddress.Any, 0);
                    int receivedBytes = _udpClient.Receive(ref remoteEndPoint);

                    byte[] frame = new byte[receivedBytes];
                    Array.Copy(_buffer, frame, receivedBytes);

                    // Process the received frame (decode, display, etc.)
                    ProcessFrame(frame);
                }
                catch (Exception ex)
                {
                    Console.WriteLine(ex.Message);
                }
            }
        }

        private void ProcessFrame(byte[] frame)
        {
            // This method should be implemented to process the received frame.
            // For example, you can decode the frame using a library like FFmpeg and display it on the PictureBox.
            // Note that this is a complex task and requires additional libraries and code.
        }

        private void pictureBox1_Click(object sender, EventArgs e)
        {
            // This method is called when the PictureBox is clicked.
            // You can add any additional logic here if needed.
        }
    }
}

This code sets up a UDP server that listens on port 12345 and receives video frames. The ProcessFrame method should be implemented to process the received frame, which may involve decoding the frame

To realize receiving and transmitting UDP packets in different threads for parallel work in Java, you can use the DatagramSocket class along with the Thread class to create separate threads for receiving and transmitting. Here's an example of a simple UDP server that handles receiving and transmitting in different threads:

import java.net.*;
import java.io.*;

public class ParallelUDPServer {
    private static final int PORT = 12345;

    public static void main(String[] args) throws IOException {
        // Create a DatagramSocket for receiving UDP packets
        DatagramSocket receiveSocket = new DatagramSocket(PORT);

        // Create a thread for receiving UDP packets
        Thread receiveThread = new Thread(() -> {
            byte[] receiveBuffer = new byte[1024];
            while (true) {
                DatagramPacket receivePacket = new DatagramPacket(receiveBuffer, receiveBuffer.length);
                try {
                    receiveSocket.receive(receivePacket);
                    processReceivePacket(receivePacket);
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        });

        // Create a thread for transmitting UDP packets
        Thread transmitThread = new Thread(() -> {
            while (true) {
                // Simulate sending UDP packets to a client
                sendUDPPacket("Hello from the server!", "127.0.0.1", 6789);
                try {
                    Thread.sleep(5000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        });

        // Start the threads
        receiveThread.start();
        transmitThread.start();
    }

    private static void processReceivePacket(DatagramPacket packet) {
        byte[] data = packet.getData();
        int length = packet.getLength();
        InetAddress address = packet.getAddress();
        int port = packet.getPort();

        System.out.println("Received packet:");
        for (int i = 0; i < length; i++) {
            System.out.print(data[i] + " ");
        }
        System.out.println();
        System.out.println("From: " + address + ":" + port);
    }

    private static void sendUDPPacket(String message, String host, int port) throws IOException {
        byte[] sendData = message.getBytes();
        DatagramPacket sendPacket = new DatagramPacket(sendData, sendData.length, InetAddress.getByName(host), port);
        DatagramSocket socket = new DatagramSocket();
        socket.send(sendPacket);
        socket.close();
    }
}

In this example, the ParallelUDPServer class creates two threads: one for receiving UDP packets (receiveThread) and another for transmitting UDP packets (transmitThread).

In UDP communication, there is no built-in mechanism to confirm if the client has received data from the server. UDP is a connectionless protocol, which means it does not establish a connection between the client and server, and therefore, it does not provide any reliability guarantees.

However, there are some techniques you can use to improve the reliability of UDP communication and get an indication that the client has received data:

1. Acknowledgment packets: The server can send acknowledgment packets after sending data to the client. The client can then send acknowledgment packets back to the server after receiving the data. If the server does not receive the acknowledgment packets within a specific timeout period, it can assume that the client has not received the data.

2. Timeout and retransmission: The server can implement a timeout and retransmission mechanism. If the server does not receive an acknowledgment packet within a specific timeout period, it can resend the data and continue to do so until it receives an acknowledgment or reaches a predefined limit.

3. Checksums or hashes: The server can send data along with a checksum or hash value. The client can then calculate the checksum or hash of the received data and compare it with the value sent by the server. If the values match, the client can be confident that it has received the data correctly.
