java.net.SocketException异常权限被拒绝

大家好，我想用下面的代码java.net.SocketException异常权限被拒绝

public class Add extends MenuActivity { 

    Button submit; 
    EditText editText; 
    private WebView webView; 

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

     String contents = urlToString("http://www.vogella.com"); 

     submit = (Button) findViewById(R.id.button1); 
     editText = (EditText) findViewById(R.id.editText1); 
//  String addUrl = editText.getText().toString(); 
     submit.setOnClickListener(new OnClickListener() 
     { 
      public void onClick(View v) 
      { 
       Log.d("Submit"," Pressed"); 
       Log.d("EditText",editText.getText().toString()); 
      } 

     }); 

    } 


    private String urlToString(String address) { 
     HttpURLConnection con = null; 
     URL url; 
     InputStream is = null; 
     try { 
      url = new URL(address); 
      con = (HttpURLConnection) url.openConnection(); 
      con.setReadTimeout(10000); 
      con.setConnectTimeout(15000); 
      con.setRequestMethod("GET"); 
      con.connect(); 
      is = con.getInputStream(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 

     BufferedReader reader = null; 
     StringBuilder sb = new StringBuilder(); 
     try { 
      reader = new BufferedReader(new InputStreamReader(is)); 
      String line = ""; 
      while ((line = reader.readLine()) != null) { 
       sb.append(line); 
       Log.d("HTTP", line); 
      } 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } finally { 
      if (reader != null) { 
       try { 
        reader.close(); 
       } catch (IOException e) { 
        e.printStackTrace(); 
       } 
      } 
      if (is != null) { 
       try { 
        is.close(); 
       } catch (IOException e) { 
        e.printStackTrace(); 
       } 
      } 
     } 
     return sb.toString(); 
    } 


}

可能[错误消息'java.net.SocketException：套接字失败：EACCES（Permission denied）']（http://stackoverflow.com/quest离线/ 11273197/error-message-java-net-socketexception-socket-failed-eacces-permission-denie） – William

我认为你必须使用

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

如果任何人仍然有这个问题，即使在Android上添加此权限后清单文件。那么可能你应该清理并重建项目。 – Aryo

我想你错过了这个权限到清单文件

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

我也有在AndroidManifest.xml此行文件

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