Всякий раз, когда я пытаюсь отправить пакет, я получаю исключение из нелегального состояния, но я не знаю, почему это происходит, насколько мне известно, каждая переменная инициализирована, и это то, что как правило, вызывает незаконное исключение государства.Android - Java - NetworkOnMainThreadException
Здесь ошибка:

А вот код, который вызывает ошибку:
public void sendMessage(View view) {
// Send UDP message to server
Log.w("myApp", "Reached Function");
try {
InetAddress IPAddress = InetAddress.getByName("144.118.119.31");
String toSend = "1";
byte [] buf = toSend.getBytes();
Log.w("myApp", "1 converted to bytes");
DatagramPacket packet = new DatagramPacket(buf, toSend.length(), IPAddress, 5005);
Log.w("myApp", "Packet created: Send to: " + IPAddress.getHostAddress() + " Send: " + buf.toString() + " " + buf.length + " " + toSend.length());
DatagramSocket csock = new DatagramSocket(5005);
csock.send(packet);
Log.w("myApp", "Sent Packet");
} catch (SocketException e) {
e.printStackTrace();
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
Любой ключ к пониманию того, что проблема и как это исправить?
