java.net.SocketException：權限被拒絕android

我創建了我的android應用程序來鏈接「www.google.com」。但是，我總是得到這樣的例外：java.net.SocketException：權限被拒絕android

，我也添加權限進入的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>

整個代碼是在這裏：

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(); 
      } 

     } 
    }); 

    } 
    }

這讓我很沮喪，謝謝你的幫助。

清理項目，並建立再 – waqaslam 2012-07-20 09:18:21

@Waqas我清理它確實有效，thx很多。 – Xenos 2012-07-20 09:29:55

普萊舍檢查類的名字，因爲

類名是

公共類HttpClientTest延伸活動{

但是你在的Manifest.xml活動

機器人：name =「.HttpClient」

我認爲你的作文更改活動名稱是「HttpClientTest」。因爲我測試你的代碼完整。

是的，它帶來了另一個問題，但它並不重要。清理完項目後，它確實有效。 thx爲你的幫助。 – Xenos 2012-07-20 10:02:52

UPDATE（從評論）您必須添加

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

爲了您的清單

原始響應

添加<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>給你的清單和檢查。
