java.net.SocketException: Permiso denegado para Android

Question

Creo mi aplicación de Android para vincular "www.google.com". Pero siempre tengo la excepción de esa manera:

y también añado el permiso en el Manifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
package="com.xenos.study.httpclienttest" 
android:versionCode="1" 
android:versionName="1.0" > 

<uses-sdk android:minSdkVersion="10" /> 
<uses-permission android:name="android.permission.INTERNET"/> 
<application 
    android:icon="@drawable/ic_launcher" 
    android:label="@string/app_name" > 
    <activity 
     android:name=".HttpClient" 
     android:label="@string/app_name" > 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 

      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity> 
</application> 

Todo el código está aquí:

public class HttpClientTest extends Activity { 


private HttpClient httpClient ; 
private HttpGet httpGet ; 
private HttpResponse httpResponse ; 
private HttpEntity httpEntity ; 

private BufferedReader br ; 
private Button link ; 
private EditText show ; 

private String path = "http://74.125.71.104"; 

/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 


    link = (Button) findViewById(R.id.link); 
    show = (EditText) findViewById(R.id.show); 


    httpClient = new DefaultHttpClient() ; 
    httpGet = new HttpGet(path); 



    link.setOnClickListener(new OnClickListener() { 

     @Override 
     public void onClick(View v) { 
      try { 
       httpResponse = httpClient.execute(httpGet); 
       httpEntity = httpResponse.getEntity(); 
       br = new BufferedReader(new InputStreamReader(httpEntity.getContent())); 

       String str = null ; 
       while ((str = br.readLine())!=null) { 

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

     } 
    }); 

    } 
    } 

Me pone triste, gracias por tu ayuda.

Answer 1

Plese compruebe su nombre de la clase, porque

nombre de la clase es

clase pública se extiende HttpClientTest Actividad {

Sin embargo, su actividad en Manifest.xml es

androide : name = ". HttpClient"

Creo que el nombre de actividad de cambio de ensayo es "HttpClientTest". Porque estoy probando tu código completo.

Answer 2

ACTUALIZACIÓN (de comentarios) Debe añadir

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

Para el manifiesto

respuesta original

añadir <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/> esto a su manifiesto y comprobar.
