07-20 16:50:31.147: W/System.err(19007):    at dalvik.system.NativeStart.main(Native Method)

and I also add the permission into the 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>

The whole code is here :

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();
            }

        }
    });

    }
  }

It makes me gloomy , thanks for your help.

UPDATE (from comments) You must add

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

To your manifest

Original response

add <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/> this to your manifest and check.

No. He'd rather use <uses-permission android:name="android.permission.INTERNET"/>

Plese check your class name because

class name is

public class HttpClientTest extends Activity {

But your activity in Manifest.xml is

android:name=".HttpClient"

I think you essay change activity name is "HttpClientTest" . Because i'm test your code complete.

SocketException: It can happen in various situations. Either the server-side closed the connection, or the client-side closed the connection.
