IOException: socket failed: ACCESS (Permission denied)

Я пытаюсь создать простое клиентское приложение Android, которое отправит строку на сервер.IOException: socket failed: ACCESS (Permission denied)

Клиент:

public class MainActivity extends ActionBarActivity { 

EditText et; 
Button btn; 

private Socket client; 
private PrintWriter printWriter; 
private String s; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    et = (EditText) findViewById(R.id.et); 
    btn = (Button) findViewById(R.id.btn); 

    btn.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 

      s = et.getText().toString(); 
      et.setText(""); 

      try { 
       client = new Socket("192.168.1.14", 4444); 
       printWriter = new PrintWriter(client.getOutputStream(), true); 
       printWriter.write(s); 

       printWriter.flush(); 
       printWriter.close(); 
       client.close(); 
      } catch (UnknownHostException ex) { 
       Toast.makeText(getApplicationContext(), "UnknownHostException: " + ex.getMessage(), Toast.LENGTH_LONG).show(); 
      } catch (IOException ex) { 
       Toast.makeText(getApplicationContext(), "IOException: " + ex.getMessage(), Toast.LENGTH_LONG).show(); 
      } 

     } 
    }); 
} 
}

Сервер:

public class Main { 

private static ServerSocket serverSocket; 
private static Socket socket; 
private static InputStreamReader inReader; 
private static BufferedReader bufferedReader; 
private static String s; 

public static void main(String[] args) { 
    char port = 4444; 

    try { 
     serverSocket = new ServerSocket(port); 
    } catch (IOException e) { 
     System.out.println("Could not listen on port " + port); 
    } 

    System.out.println("Server started. Listening on port" + port); 

    while (true) { 
     try { 
      socket = serverSocket.accept(); 
      inReader = new InputStreamReader(socket.getInputStream()); 
      bufferedReader = new BufferedReader(inReader); 
      s = bufferedReader.readLine(); 

      System.out.println(s); 
      inReader.close(); 
      socket.close(); 
     } catch (IOException e) { 
      System.out.println("Problen in message reading!"); 
     } 
    } 
} 

}

Я также добавил разрешение INTERNET.
Я на самом деле запускаю сервер на DrJava, это может быть проблемой?

Я получаю сообщение об ошибке: «IOException: socket failed: ACCESS (Permission denied)».

show log cat ... –

Можете ли вы разместить свой AndroidManifest.xml? –

@NoName добавил log cat – AnDrOiD

Запишите этот фрагмент ниже setContentView()

if (android.os.Build.VERSION.SDK_INT > 9) { 
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build(); 
StrictMode.setThreadPolicy(policy); 
}

или

class MyTask extends AsyncTask<Void, Void, Void> { 

@Override 
protected void onPreExecute() { 
    super.onPreExecute(); 
    } 

@Override 
protected Void doInBackground(Void... params) { 
    // Do your request 
} 

@Override 
protected void onPostExecute(Void result) { 
    super.onPostExecute(result); 

} 
}

Как насчет объяснения? – AnDrOiD

http://www.androiddesignpatterns.com/2012/06/app-force-close-honeycomb-ics.html –

отключить StrictMode совсем не очень хорошо. Попробуйте asynctask. –

Исключение NetworkOnMainThreadException будет выброшен, когда приложение пытается выполнить операцию сети на своем главном потоке ,

Таким образом, вам необходимо выполнить сетевую операцию в новом Thread or AsyncTask.

Ниже приведен пример,

public void onClick(View v) { 

    s = et.getText().toString(); 
    et.setText(""); 
    /*run socket related code in new thread*/ 
    new Thread(){ 
     public void run() { 
      try { 
       client = new Socket("192.168.1.14", 4444); 
       printWriter = new PrintWriter(client.getOutputStream(), true); 
       printWriter.write(s); 

       printWriter.flush(); 
       printWriter.close(); 
       client.close(); 
      } catch (UnknownHostException ex) { 
       ex.printStackTrace(); 
      } catch (IOException ex) { 
       ex.printStackTrace(); 
      } 
     } 
    }.start(); 


}

В примере кода printStackTrace() будет печатать журнал трассировки, если происходит ошибка.

Ну, теперь я не получил никакого исключения. Но я не вижу никаких изменений на сервере. Может быть, IP должен быть чем-то другим? – AnDrOiD

во-первых, проверьте журнал, чтобы узнать, не выбрасывает ли какое-либо исключение. – yummy

Выбрасывается «SocketException». – AnDrOiD
