Android客戶端套接字拋出SocketException：

我想在android中實現java套接字客戶端，我的服務器是我的筆記本電腦。我希望我的android手機通過java套接字連接到筆記本電腦。但我在客戶端發生異常：「SocketException」，它看起來是因爲socket（）調用無法正確創建套接字。以下是我的Android客戶端代碼進行審查。有沒有什麼解決的決心異常：Android客戶端套接字拋出SocketException：

public class SimpleActivityExampleActivity extends Activity { 

/** Called when the activity is first created. */ 
private String usrName; 
private String vendorName; 
private String message; 
public Socket socket; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
    } 


public void submitTheForm(View view) { 

    final EditText edittext1 = (EditText) findViewById(R.id.editText1); 
    final EditText edittext2 = (EditText) findViewById(R.id.EditText01); 
    final EditText edittext3 = (EditText) findViewById(R.id.editText2); 
    usrName = edittext1.getText().toString(); 
    vendorName = edittext2.getText().toString(); 
    message = edittext3.getText().toString(); 
    message = usrName+ "," + vendorName + "," + message; 

    byte[] msg = message.getBytes(); 
    try { 
    InetAddress serverAddr = InetAddress.getByName("192.168.1.2"); 
     Log.d("ClientActivity", "C: Connecting..."); 

     socket = new Socket(serverAddr, 2200); 
    socket.getOutputStream().write(msg); 
    socket.getOutputStream().flush(); 
    } catch (UnknownHostException e) { 

     Toast.makeText(SimpleActivityExampleActivity.this, "unknownhostException", Toast.LENGTH_SHORT).show(); 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } catch (SocketException e) { 
     // TODO Auto-generated catch block 

     Toast.makeText(SimpleActivityExampleActivity.this, "Sockexception", Toast.LENGTH_SHORT).show(); 
     e.printStackTrace(); 
    }catch (IOException e) { 
     // TODO Auto-generated catch block 
     //System.out.println("in IOexception for sure"); 
     Toast.makeText(SimpleActivityExampleActivity.this, "IOexception", Toast.LENGTH_SHORT).show(); 
     e.printStackTrace(); 
    } 
    catch (Exception e){ 
     Toast.makeText(SimpleActivityExampleActivity.this, "Exception", Toast.LENGTH_SHORT).show(); 
     e.printStackTrace(); 
    }finally { 
     if(socket != null){ 
      try { 
       socket.close(); 

      } catch (IOException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } 
     } 
    } 
} 
}

submitTheForm（）函數被調用從main.xml中的文件「機器人：的onClick = 「點擊一個按鈕submitTheForm」

你可以請張貼與異常關聯的堆棧跟蹤嗎？ – slayton

你有沒有設置

<uses-permission android:name="android.permission.INTERNET" />

權限？

發現這個here

是否有可能你忘了Internet權限添加到您的清單文件？

<uses-permission android:name="android.permission.INTERNET" />
